I have wooden floors and live in an apartment building. I installed the Soundpath isolation feet and my floors do not vibrate anymore. My neighbors and I are happy :)
Story time: I pushed my heavy PB-16 across the carpet. The isolation rubber detached from the coupling (It fits back on, not a big deal). I saw quickly that I need a moving men carpet slide under it. Moved the PB-16 a few feet into its new home. KEPT the carpet slide underneath the rubber foot. Even better results. The smooth hard plastic on the carpet, and the foam top, under the rubber foot is quite amazing, even accidentally so. For carpet applications, this is a new level of amazing.
Not everyone would benefit from having the SoundPath Isolation System depending on the floors and room so we offer as an add-on. Plus, it adds height, which can be a negative for people with tight sized spaces.
Very pleased with the effectiveness of these feet. When I bought my first SB2000 I also bought SVS feet for it. No issues. When I added a second SB2000 I held off getting the feet to save a few bucks. My subs sit on carpet on a second floor. I just added SVS feet to the second sub. What a noticeable improvement to my bass! (And, I was very pleased with these dual subs before). Now my bass is really nicely balanced. It sounds bigger and tighter. I was apparently getting some floor stuff in my overall sound. These SVS isolation feet are well worth it!
I do like these feet and have used them on my last several subs. Huge kudos for going in to detail about what floors these do and don’t work with. Even though they don’t effect my sound, they do look really nice and make it super easy to move when needed.
I put my rel sub on some material used to reduce vibrations created by washing machines. Worked well. It's like the matting they use in children's playparks
I live in an concrete apartment with hardwood floors. My dishes were rattling even with low to moderate subwoofer volume on my crappy 100w RMS 10" sub. After installing the isolation feet no rattles whatsoever. I'm sure my neighbors appreciated it too.
1) Spikes 2) Sound transducers...ie...bass shakers + turn down the volume 3) Cut up some sorbothane squares 4) Lots of other sound-deadening options if you're creative 5) These should come free with their subwoofer purchase
Nice review thank you. My sb3000 is positioned on a stool because positioning it on the wooden floor means all the sound would go underneath the bed. My living space is too small and I'm almost in trouble with neighbours due to the sub energy. What I would like you to kindly tell me is: Would the isolation feet work well why sub is on the stool or not?
I do like these feet and i bought them for my Klipsch subs and it works excellent & it's stopped vibrating the floor windows and door & the sube sound more cleaner.
My window had a rattle, now with these feet the rattle is gone.....better low end bass,,, worth the money...the haters should shut up...don’t try ,don’t buy...highly recommendable product.!
I personally love being able to feel the bass in our house as we have wood floors foundation. I of course had to de-rattle some pictures,doors etc... but there is nothing better than actually feeling the bass in our seats and feet. You get a genuine feeling of being there. The house we had prior had a concrete foundation and you just didnt get the same feeling. I do find it odd though that some people don't want it. I get not wanting rattles but dialing down the "boom" just doesnt appeal to me. I wonder if the people who dont like it have ever considered just getting a smaller sub?
Hell yes! Nothing like that incredible tactile effect. But keep in mind, just because you physically isolated the sub from the structure/flooring, you wouldn't necessarily diminish the tactile effect of your sub system. It might remove something that you like, but subjectively it could easily sound cleaner, tighter, and with more impact. A few years ago an audio enthusiast group (Physicists to Physicians) really went deep down the tactility rabbit hole. So much was explored both individually and collectively, much was learned and shared throughout the enthusiast community. The tactile component of sound, ... fascinating stuff. Feeling the energy in your seats and in your feet is great. The mechanical energy directly transmitted to the floor from the bottom of the box is essentially like another sub. You've got energy coming from the floor via the sub's feet, and acoustic energy coming from the cone. The problem is time alignment. The differences in arrival times can blurr the transient in time ... thus muddying and softening it's impact. It's distortion. Compared to air, the floor transmits the signal faster and introduces distortions/resonances. Whether home, live sound, or in the studio, any system with multiple LF sources, one goes to great lengths to assure each LF source sums ADDITIVELY at the listening position, with ideal time alignment for maximum impact. That mechanical energy generated from the sub's feet you can't properly control and align for summation at the listener. A trend over the last 10yrs or so is utilizing approaches like nearfield subs to heighten that tactility. Another approach is tactile transducers such as the superb Crowsons (butt kickers, just high quality). But these additional sources are all adjustable in alignment in the time domain relative to both the LCR mains, and the subs. Sorry, waaay too deep into the weeds, being I'm all C-19 quarantined and locked down, ... point being that killer tactile effect may get even better if you isolate your subs. The acoustic output alone may create much of the same. Thanks and best of luck (Fwiw, in my primary media system, I've got 6x12"s in the two octaves between 60-240hz, from there down I'm rockin' 4x15"s, 4x18"s. The 4x15"s are dual-opposed Seaton Submersives, so by design they don't generate any energy via their feet. You can stand a nickle on end and pump full tilt kick drum thru the thing and the cabinet will not knock the coin over! The 4x18"s are an Infinite Baffle sub manifold mounted in my attic outputting into my listening room. Via eight channels of Ashley Protea DSP adjustment I time align and blend the six LF sources so they all sum properly and smoothly across the sofa seating. It's not a dedicated Home Theater, simply a modest system in a rectangular family room with attached kitchen, approx 29'x13'x8'). *it's funny btw, this video wasn't really about "Room Rattle and Bass Bleed", it was merely a 7:43 advertisement for their product. I've got nothing against SVS, I dig what they do, just saying.
@@FOH3663 so you recommend isolation with multiple subs? I tend to like the rumble and am thinking about enhancing it with spikes (I'm on carpet). I've tried nearfield and I did not like the sound.
@@matsudakodo The isolation simply eliminates physical energy from the subwoofer transferring to you via the floor. Yes, strongly recommended. That cleans up any transient blurring via differing time arrivals. Ideally just the wave-launch propagating from the driver is the only source you want to experience. That energy can set the floor and everything else in motion. The other undesirable scenario is this; As the woofer strokes, the woofer frame/magnet assembly is held still by the box. But the equal and opposite reactionary forces are transferred to the cabinet. The cabinet transfers those forces to the flooring. The flooring transfers this energy to the seating and most likely the feet of the listener. So this vibrational energy is straight up distortion. It's out of phase, and mis-aligned with the wave-launch bass from the sub... and this vibrational distortion signal gets to the listener first. The speed of sound propagating via the air is slower than the well coupled speed transfer through the floor. Thus the potential blurring of transients. They do a terrible job of explaining this in the video.
I just installed a set on my really old Advent 15" powered down firing subwoofer (modded). I could of went the hockey puck route like some people, but the SVS Subwoofer Isolation System looks much nicer, and give my subwoofer a cleaner look. Now my old neighbor stopped knocking on my door asking me did I felt an earthquake. That means now I can push my sub just a little more... Just a little. LOL!
I have two identical subs mid wall Placement.A pro told me that nowadays it pretty common two have Them 180° and 0° phase. I use Dirac Bass Control and did a new measurment with different Phase settings.Whats your opinion?😊.
I purchased the SVS SoundPath Isolation System w/my HT subwoofer b/c I lived in a second-floor apartment. Got them for better sound quality and out of respect & consideration of disturbing neighbors. No regrets. It’s working fine, and I wouldn’t run a sub w/o them now. Consider it a part of sub. It’s also a reasonable price, not ridiculous. I use floor isolation pads for two smaller down-firing subs in a stereo rig in other room. In comparison, I like the SoundPath Isolation Feet better.
gotta say the sound path isolation system was the best $100 I ever spend, I live in a town house and have duel 12" Klipsch THX Ultra2 subs, and my neighbors use to pound on my walls when ever i'd watch a movie or play a game, they stopped doing that as soon as I put these feet on, Don't get me wrong I can't crank my system to reference levels or anything, but at least I can have my subs turned on now and actually use them at reasonable levels.
No kidding, I don't have that problem since I am in a house but my Klipsch sits directly on tile and was wondering how to stop the vibrating and rattling on walls.
The spikes won't decouple the subwoofer from the floor. That said, if you're not experiencing any room rattle or resonances with them installed, there's no reason to upgrade to the SoundPath Isolation System.
@@SVS_Sound 90lbs+? My loudspeakers have 15's, and the house has hardwood floors throughout, so I'm quite interested is seeing how much vibration it would eliminate.
If you're noticing rattles in other pats of the room like fixtures and windows, then yes. Concrete floors are inert so the floor vibrations shouldn't be an issue.
I ordered the isolation system with my pb2000 last year from the outlet on your site. I haven't tried it without those and don't plan to, lol. I found a sweet spot for the apartment I'm in using Put On by Young Jeezy. It's more of a middle ground spot. You hear and feel the low intro tone. Which I what I wanted. If I rearrange everything I'll lose everything above 50hz. I'm content with the middle ground. Every frequency is satisfactory. Can't even think of upgrading yet because I haven't had a chance to open this baby up due to living circumstances.
I want to buy them but it costs more than my subwoofer cost. What to do? My neighbour is complaining about my bass thumping. But i want to enjoy it, instead of these isolation pads can i buy washing machine vibration pads? Will they work for it.?
There are hockey puck sized rubber vibration reducing devices designed for washing machines that work well for a fraction of the cost, like $20 -30 for a package of 4.
hahah thank you for this comment, i ordered isoacoustics puck and then these washing machine anti vibration pads, both gave same results so i returned the isoacoustics which were $$$ as compared to $
I have a sub in front of my fireplace and it makes my fireplace boomy and sometimes rattle. How can I prevent this from booming and this is the only spot I can place the subwoofer?
Add these svs isolation feet to your sub and it will reduce floor boom which is what's causing your fireplace to rattle. That's the whole point of these.
I’m about to purchase a Pangea Audio Vulcan Turntable Stand (holding about 100 vinyl LPs, a Sony 400-CD changer, and a Fluance RT85 turntable) and will place the stand on a hard wood (Hickory) floor, but I’m not too keen on using Pangea’s spikes on their tiny discs. Would it be possible to replace the spikes entirely with these acoustic isolators? Or can the spikes be secured into the small isolator holes? Or can you recommend another SVS product that will work for this application? Thanks in advance!
Yes, it is possible. You can also use double sided tape or sticky foam to adhere the Isolation System to the turntable stand if you prefer over the spikes.
Unless it's on a brick wall or a reinforced steel beam then no.. i wouldn't recommend having it drywall anchored nor stub wall mounted at all. The vibrations alone cause it to be a hazard no matter the clamping force you put.
Do not work for Polk subwoofers like PSW111, unfortunately. Those have glued feet held down by a simple wood screw. Not sure whether I can remove them without pulling vinyl off MDF.
I run these on my NHT 2.5 towers. They have built in side firing 8” subs and the sound was noticeably cleaner after installation. Great product at a reasonable price. I needed two sets of 4, but the cost was well worth it. Don’t hesitate.
I have the pb2000 on the second floor, wooden floor boards with carpet. Do you think the isolation feet will work well with providing a cleaner, tighter bass?
@@SVS_Sound I would love that, however, as a UK customer this will not be possible. But, I do trust your products so I know I can buy them anywhere and not be disappointed 😁
These guys are great. Ed drafted an order to add the SoundPath isolation feet for my new SB-4000 that should get some setup love later today. Love SVS ❤️ 🔊
These feet help, but my PB-1000 Pro still shakes our room (and the neighbors) when I go to -10 dB or above watching bass-heavy action movies. Are there room treatments I could add to help?
Bass traps can help with in-room response. An additional isolation platform could also help with the vibrations but hard to eliminate alltogether, especially with ported subwoofers.
Room gain compensation is very useful if you want to crank your subs up more while being able to hear the low end without the energy. Very useful feature!
im using the prehistoric relq100e and never knew about floor boom.........i have wooden floors and when i ran the thx deep note test at the end of the avatar blu ray the final part of the test i thought my sub was having a heart attack it sounded awfull........thank god i live in a detached propety...perhaps the supplied spikes are doing it any good?
The spikes keep it off the floor but generally don't decouple it from the room. Many people find adding the Isolation System eliminates the floor boom and room rattle, especially with wood floors.
Nice video trying to solve this problem with my home theater that’s in my basement walls are made of acoustic fiberglass from Owens Corning... the walls I do not think are transferring really much energy to the rest of the house but the ceiling is... more specifically the floor above is... the ceiling is a drop fiberglass ceiling which the bass waves pass directly through for the most part... I know adding fiber glass insulation in the ceiling can only do so much with bass waves but I think if I put in denser ceiling tiles overhead instead of the fiber glass ones I currently have the combination should help me correct the problem? Right? My logic is that a drop ceiling for the most part is decoupled from the floor above as it is suspended, I’d prefer that to take on more of the bass wave impact first. Then the fiber glass insulation can help reduce whatever is left over. I’m also going to try and rap duct work with insulation to cut down on resonance through there... is there any thing you suggest I do to my ceiling that’s relatively affordable? Am I headed in the right direction? I’d prefer to stick with a drop ceiling as I love the quick and easy access for wiring.
Adding some insulation above the drop ceiling tiles will greatly reduce their potential to buzz/rattle and will also provide some sound dampening and bass trapping.
U used these on an Elac 3010, passive radiator , the whole sub is almost jumping at low frequency it doesn't happen with spikes, I'm not sure why, but at other normal range it does sounds cleaner.
The video mentions that the height was optimized as well in testing. I'm putting these on some custom subwoofers but I need to add a 3/4 inch "spacer" (for lack of a better word) between the feet and the base of the subwoofer because my cable connection will be at the bottom of the sub. Does adding that spacer (3/4 inch mdf "puck" the diameter of the soundpath feet) negatively affect the ability of the soundpath feet from doing its job?
Will these make much difference on a floor with carpet? Received my SB-3000 this week and running it with my Yamaha YSP-5600 sound bar. It’s unbelievable!!
It really depends on how your room is interacting with the subwoofer output. If you hear windows and other things rattling , or it's bothering neighbors roommates, it will help. You can also return at no cost within 45 days if there's no improvement.
You should not be hearing a buzzing coming directly from the subwoofer though it is not uncommon for subwoofer output to cause things in the room to buzz at certain frequencies. If it's an SVS subwoofer, please contact our support team to dive deeper into the issue custservice@svsound.com.
FYI Isoacoustics offer a similar product which I can wholeheartedly recommend. The have the Gaia or Orea which seek to decouple as well, but use calibrated a weight based loading system, which would be more effective than using this SVS system on other branded products (since the weight loading factor would change).
Not sure how well these will work for down firing subs maybe need an extra platform perhaps a granite slab with a couple of sets of these one to isolate slab from floor and one to isolate sub from slab .
Not worried so much about things vibrating except the sub itself. My Dynamo 700 subs tend to "dance around" on the hardwood floor sometimes and I' keep having to put them back in place. They sound great... just a PITA.
@@HeretixAevum True that. These things cost $50 for some rubber feet too. You can achieve the same effect with a pad of high density closed cell foam for about $2 ... Unless you have a downfiring sub of course. I have my sub on a concrete floor covered with linoleum tiles. The room has rattles and buzzes so I watched this to see what I could do about that, as per the clickbait title. This information was useless to me, those neat little shoes for my sub would not help and they really didn't cover anything else that my system can do to remedy this problem.
Hi SVS!😊 I'm currently on the market for purchasing a small compact subwoofer for my apartment. I've considered many brands, but landed on SVS. I'm currently looking at the SVS SB-1000, but my question is. Are you guys planing on making a similar sub, but with a 10" driver, to make the cabinet even smaller? Cheers,
Technically speaking that I don't think so that every one should need a extra pair of rubber pads to decouple the subwoofer and its low frequencies from the ground especially floors with carpets on it and on cemented floors. Because in my experience I already listened different types of subs some with bass reflex, some with passive radiator, and some build with the tech of air suspension which you also called them as sealed for a long enough. These types of floors doesn't digest enough frequencies which have been reproduce by the subwoofer itself so in this case you will still get a decent amount of power driven out to you as deep as the subwoofer can handle the acoustics upto. ("MAY BE RECOMMENDED FOR HARD WOOD SURFACES AS THEY RESIST SOME LEVEL OF FREQUENCIES")
All down-firing SVS subwoofers come standard with the SoundPath Subwoofer Isolation System. They will also work with other brand models as long as there is enough clearance for full excursion and the screw thread size works.
Should try this with my desktop's sound system. There's literally a joist under the floor right where my desk setup is and a double joist under the wall the desk is in front of... The bass vibrations basically go though the floor into the joints and into the center beam of the house much to my mother's announce.
It should definitely help with the energy transference in your scenario. There is a 45 day risk free trial so you could test and return at no cost if there is no noticeable difference.
@@SVS_Sound I tried it with a scrap peace of hard foam it definitely makes a difference in both the thump of the bass traveling though the beams and less revirb resulting in cleaner bass. So I'll definitely be doing something more permanent.
❤️❤️❤️❤️ Been doing this since my first home theater I setup for my Mom in 9th grade!!!! Harry Potter, Lord of the Rings, and Star Wars were my motivations! I feel blessed to have been a nerd in that wonderful era!
hello can someone please help me my neighbor is some how playing sonic sounds all over my house my 89 granmother scaird cant sleep please tell me how i can stop pit
There are many solutions so they dont dig into your wooden or marble floors. I was thinking since the tip of spike makes minimal contact with floor it's a positive thing. I honestly dont know much about It though. And am learning by hearing y'alls input. Thanks!
@@HermesTrismegistes369 I would think that would couple the sub to the floor and increase the transmission. Good for those of us who have a room where we like the effect.
A $1000 sub should come with them. Then you pay $100 for 8. Im glad i got carpet and all klipsch speakers with 2 12inch subwoofers. Sounds amazing. No rattling or nothing.
I got a dual setup with pb2000s coupled with the sound patch. Still got threats from neighbours that they would call the cops on me. They live three floors down under me. 😂 I stopped the party right then and there. 😂
I have 3 SVS subs, 2 PC-13 ultras, and 1 PB-12 NSD. What I did was use the shipping foam and then cut plywood to cover the foam and put the subs on top of those. The PB-12 NSD has a mechanics dolly under it. Do you think these pads would work better than what I did? I live in a manufactured home and you know what kind of rumble that is, hole house, neighboorhood, I also have bass traps and acoustic foam all around the room. I'd be glad to try them out if you think it would be better than what I have now. Fantastic Subs I must say...
Thanks! Given the research we put into the materials and testing, it would almost certainly have a positive impact on reducing rumble and rattle you have vs. the current solutions. My recommendation would be to take advantage of the SVS 45-Day trial and install on 1 of the subwoofers to see the effects and then return at no cost or add to the other 2 subwoofers if you notice major improvement.
@@SVS_Sound Yeah, I don't think I'd be able to notice anything with only 1 set of pads. I wouldn't want to turn the other two off because it wouldn't be the same sound I know, and love. I like my music at concert levels, lol... Thank you SVS Keep up the Damn good work!
I built a pair of subwoofer platforms with four tennis balls each sandwiched between 1-inch thick boards. I used a door hole saw to recess the tennis balls and hold them in place. This greatly reduced the mechanical transfer from my subs to the floor and seems to tighten the bass sound considerably.
My neighbors were not happy about my lows vibrating their lady parts each time I played music. Finally they can sleep and no more wet dreams. I took the concept and design my own pads, but thanks for sharing
My subs (dual pb3000's) are in my basement on Cement. I still get lots of vibration and rattle. Bass throughout the upstairs. I have figured there's not much I can about it. Yes?
You may want to try the SoundPath Isolation System with the 45-Day trial, and if they don't help mitigate some of the vibrations, send them back at no cost. Beyond that, there are things you can do to soundproof the basement, like insulation between the floors or installing other dampening materials,
I have/had this problem on both my windows in my listening. Older windows that rattled like crazy. Of course not everyone can do what I did. I drove in 2 machine screw inserts into my window frames on the left and right side. Then I took a oak 1X2 and made clearance holes for a threaded knob and a stud on each end for the inserts. Now I have a cross member running across my window. Then I made a wedge from a of a block of wood to press against the glass in the center of the window and this temporary cross member and that puts the glass under pressure and prevents rattles. I can put both up in a few minutes for a longer and/or higher volume listening session. I figured when it is time to sell it, I'll fill the holes with a wood plug and stain to match. You may be to able to the inserts next to the window but under pressure did not want the drywall anchors to pulling out. I find I need quite a bit of pressure against the window glass. Volume/frequency dependent of course. You can test this by just by putting pressure on the glass in the center with your thumb.
@@briansimmons5363 yeah I have the same problem as soon I push aganist the window the rattling stops. So I might have to do some mechanical work as well or just invest into better sealed windows
Hi, I have the isolation feet and I'm still getting vibrations in my walls, doors and ceiling. My sub is in my basement which has a concrete floor with vinyl floating flooring on top. What can I do to reduce vibrations?
There are some updates you can make within the DSP that can help attenuate. Please send our support team a note at custservice@svsound.com and they can walk you through the options.
I have the same sub but in my bedroom lower notes like 20hz can still be heared and it's shaking a lot my rear wall and door even at a normal level. Which is not the case with my preview subwoofer in the same room even at a very high volume. It's the proof that even the smallest svs sub provide a lot of energy even under 24 hz
I have wooden floors and live in an apartment building. I installed the Soundpath isolation feet and my floors do not vibrate anymore. My neighbors and I are happy :)
Story time: I pushed my heavy PB-16 across the carpet. The isolation rubber detached from the coupling (It fits back on, not a big deal). I saw quickly that I need a moving men carpet slide under it.

The smooth hard plastic on the carpet, and the foam top, under the rubber foot is quite amazing, even accidentally so. For carpet applications, this is a new level of amazing.
For how much we are already paying for the subs why don’t the isolation pads come with the subwoofer along with the tiny ones?
correct
Agreed. I don't think including a set of $50 feet would've been unreasonable considering the $1400 my PB3000 cost.

Yes, the Isolation System will decouple the subwoofer so it will add additional vibration dampening that will help with the neighbor issues.

*it's funny btw, this video wasn't really about "Room Rattle and Bass Bleed", it was merely a 7:43 advertisement for their product. I've got nothing against SVS, I dig what they do, just saying.
@@FOH3663 so you recommend isolation with multiple subs? I tend to like the rumble and am thinking about enhancing it with spikes (I'm on carpet). I've tried nearfield and I did not like the sound.
@@matsudakodo
The isolation simply eliminates physical energy from the subwoofer transferring to you via the floor.
Yes, strongly recommended.
That cleans up any transient blurring via differing time arrivals.
Ideally just the wave-launch propagating from the driver is the only source you want to experience. That energy can set the floor and everything else in motion.
The other undesirable scenario is this;
As the woofer strokes, the woofer frame/magnet assembly is held still by the box. But the equal and opposite reactionary forces are transferred to the cabinet. The cabinet transfers those forces to the flooring. The flooring transfers this energy to the seating and most likely the feet of the listener.
So this vibrational energy is straight up distortion. It's out of phase, and mis-aligned with the wave-launch bass from the sub... and this vibrational distortion signal gets to the listener first.
The speed of sound propagating via the air is slower than the well coupled speed transfer through the floor. Thus the potential blurring of transients.
They do a terrible job of explaining this in the video.
Thank you for breaking down how the isolation system helps. Much appreciated!
I just installed a set on my really old Advent 15" powered down firing subwoofer (modded). I could of went the hockey puck route like some people, but the SVS Subwoofer Isolation System looks much nicer, and give my subwoofer a cleaner look. Now my old neighbor stopped knocking on my door asking me did I felt an earthquake. That means now I can push my sub just a little more... Just a little. LOL!
I have two identical subs mid wall Placement.A pro told me that nowadays it pretty common two have Them 180° and 0° phase.
I use Dirac Bass Control and did a new measurment with different Phase settings.Whats your opinion?😊.
Where can I download the SVS desktop wallpaper as shown in the display in the background.
I purchased the SVS SoundPath Isolation System w/my HT subwoofer b/c I lived in a second-floor apartment. Got them for better sound quality and out of respect & consideration of disturbing neighbors. No regrets. It’s working fine, and I wouldn’t run a sub w/o them now. Consider it a part of sub. It’s also a reasonable price, not ridiculous. I use floor isolation pads for two smaller down-firing subs in a stereo rig in other room. In comparison, I like the SoundPath Isolation Feet better.
Thanks for sharing your feedback!
gotta say the sound path isolation system was the best $100 I ever spend, I live in a town house and have duel 12" Klipsch THX Ultra2 subs, and my neighbors use to pound on my walls when ever i'd watch a movie or play a game, they stopped doing that as soon as I put these feet on, Don't get me wrong I can't crank my system to reference levels or anything, but at least I can have my subs turned on now and actually use them at reasonable levels.
No kidding, I don't have that problem since I am in a house but my Klipsch sits directly on tile and was wondering how to stop the vibrating and rattling on walls.
So for carpet the spikes that seem to come standard on the sub in the video would be just fine then?
The spikes won't decouple the subwoofer from the floor. That said, if you're not experiencing any room rattle or resonances with them installed, there's no reason to upgrade to the SoundPath Isolation System.
@@SVS_Sound is there a better way to decouple the sub if it's on carpet? Im assuming that this soundpath product isn't meant for carpets?
Joost Geurts Van Kessel it even helps on carpet.
I think spikes would couple the sub to the floor, increasing transmission of rumble.
I have a question if I may ask. What would be considered the weight limit of the isolation feet?
If using correctly with the proper number of feet replacing existing subwoofer feet, there's no official weight limit.
@@SVS_Sound 90lbs+? My loudspeakers have 15's, and the house has hardwood floors throughout, so I'm quite interested is seeing how much vibration it would eliminate.
do you sell the support for the central channel showed on 06:40? love it
How about vinyl flooring on top of a concrete slab? Will the pads make any difference?
If you're noticing rattles in other pats of the room like fixtures and windows, then yes. Concrete floors are inert so the floor vibrations shouldn't be an issue.
Do they work on any subwoofer like 18 inch
$50 for a product that takes under $5 to make. Why not just include them with the subwoofers that are being sold?
Simple because they can sell it and make $50.
thepiecesfit makes you think if their subs a priced reasonably aswell.
😃😄
@@youssefhamidi8152thats when I look to China 😂
I think we can add a foam instead
I ordered the isolation system with my pb2000 last year from the outlet on your site. I haven't tried it without those and don't plan to, lol. I found a sweet spot for the apartment I'm in using Put On by Young Jeezy. It's more of a middle ground spot. You hear and feel the low intro tone. Which I what I wanted. If I rearrange everything I'll lose everything above 50hz. I'm content with the middle ground. Every frequency is satisfactory. Can't even think of upgrading yet because I haven't had a chance to open this baby up due to living circumstances.
What about a floor with tiles ( vitrified ) ?
I want to buy them but it costs more than my subwoofer cost. What to do? My neighbour is complaining about my bass thumping. But i want to enjoy it, instead of these isolation pads can i buy washing machine vibration pads? Will they work for it.?
Would these help on carpet in a flat?
Yes. They will help any time you are experiencing vibrations or noise artifacts from the subwoofer's output.
There are hockey puck sized rubber vibration reducing devices designed for washing machines that work well for a fraction of the cost, like $20 -30 for a package of 4.
hahah thank you for this comment, i ordered isoacoustics puck and then these washing machine anti vibration pads, both gave same results so i returned the isoacoustics which were $$$ as compared to $
hi thank you for this video, also love the way you guys sit on that couch, very symmetrical
My PC 13 ultra has been kickin ass for the past 7 years. The feet have been golden.
I have a sub in front of my fireplace and it makes my fireplace boomy and sometimes rattle. How can I prevent this from booming and this is the only spot I can place the subwoofer?
Add these svs isolation feet to your sub and it will reduce floor boom which is what's causing your fireplace to rattle. That's the whole point of these.
Great video, For the floor I use washing machine rubber dumper it cost 5$ the 4 pieces it's ugly but it works
I’m about to purchase a Pangea Audio Vulcan Turntable Stand (holding about 100 vinyl LPs, a Sony 400-CD changer, and a Fluance RT85 turntable) and will place the stand on a hard wood (Hickory) floor, but I’m not too keen on using Pangea’s spikes on their tiny discs. Would it be possible to replace the spikes entirely with these acoustic isolators? Or can the spikes be secured into the small isolator holes? Or can you recommend another SVS product that will work for this application? Thanks in advance!
Yes, it is possible. You can also use double sided tape or sticky foam to adhere the Isolation System to the turntable stand if you prefer over the spikes.
Overpriced feet, you can buy anything with the same effect for around 10$ no need to pay 50$.
What do you recommend?
Is it applicable only for down firing subwoofer ?
No, any subwoofer will benefit if it's creating sonic artifacts in the room.
Opinions on having a subwoofer wall mounted? Assuming it’s secure. My concern is with the wall/house.
Unless it's on a brick wall or a reinforced steel beam then no.. i wouldn't recommend having it drywall anchored nor stub wall mounted at all. The vibrations alone cause it to be a hazard no matter the clamping force you put.
Do not work for Polk subwoofers like PSW111, unfortunately. Those have glued feet held down by a simple wood screw. Not sure whether I can remove them without pulling vinyl off MDF.
I run these on my NHT 2.5 towers. They have built in side firing 8” subs and the sound was noticeably cleaner after installation. Great product at a reasonable price. I needed two sets of 4, but the cost was well worth it. Don’t hesitate.
I have the pb2000 on the second floor, wooden floor boards with carpet. Do you think the isolation feet will work well with providing a cleaner, tighter bass?
Yes, that is a scenario where it would be effective, If you don't notice a difference, you can return within 45 days and we'll pay shipping.
@@SVS_Sound I would love that, however, as a UK customer this will not be possible. But, I do trust your products so I know I can buy them anywhere and not be disappointed 😁
These guys are great. Ed drafted an order to add the SoundPath isolation feet for my new SB-4000 that should get some setup love later today. Love SVS ❤️ 🔊
am having sony iv300 dth home theater. am not happy with subwoofer. Please Suggest an replacement for that subwoofer.
The SB-1000 Pro would be a great alternative with deeper, more powerful bass if you're system has speaker level or RCA outputs.
Will this work for a downfiring 10 inch sub like the one on the JBL Bar 9.1?
Yes/ In fact our PC series cylinders are down-firing and come standard with the SoundPath Isolation System.
Could I use these under B&W 804 D3 speakers instead of spikes? Thanks.
Yes, they can be used on speakers, turntables, and other components.
I’m getting it for my SB2000 on concrete ceramic tile floor. Not for floor boom but to raise the sub off the floor when we mop. It looks cool too
Can these work for floor standing towers?? And how much weight can they handle??
Yes, they can be used on speakers, turntables and other components and can handle 500+lbs.
DOES IT MAKE A DIFFERENCE IF THE SUBWOOFER SITTING ON A CARPET RATHER THAN FLOOR FOR THE RATTLING?
Of course it does thick carpets absorb sound
If my sub is on carpet do I need to use these or not?
If you are experiencing room resonances, they can still help reduce noise artifacts on carpet.
These feet help, but my PB-1000 Pro still shakes our room (and the neighbors) when I go to -10 dB or above watching bass-heavy action movies. Are there room treatments I could add to help?
Bass traps can help with in-room response. An additional isolation platform could also help with the vibrations but hard to eliminate alltogether, especially with ported subwoofers.
Room gain compensation is very useful if you want to crank your subs up more while being able to hear the low end without the energy. Very useful feature!
im using the prehistoric relq100e and never knew about floor boom.........i have wooden floors and when i ran the thx deep note test at the end of the avatar blu ray the final part of the test i thought my sub was having a heart attack it sounded awfull........thank god i live in a detached propety...perhaps the supplied spikes are doing it any good?
The spikes keep it off the floor but generally don't decouple it from the room. Many people find adding the Isolation System eliminates the floor boom and room rattle, especially with wood floors.
What is the maximum weight that can be installed on top of a six pack?
We tested and approved up to 500lbs. May actually be more.
Can I use them on regular speakers to help reduce vibration so that I don’t upset my neighbours?
Yes, many owners use them on speakers, turntables, and other components to reduce vibrations.
Nice video trying to solve this problem with my home theater that’s in my basement walls are made of acoustic fiberglass from Owens Corning... the walls I do not think are transferring really much energy to the rest of the house but the ceiling is... more specifically the floor above is... the ceiling is a drop fiberglass ceiling which the bass waves pass directly through for the most part... I know adding fiber glass insulation in the ceiling can only do so much with bass waves but I think if I put in denser ceiling tiles overhead instead of the fiber glass ones I currently have the combination should help me correct the problem? Right?
My logic is that a drop ceiling for the most part is decoupled from the floor above as it is suspended, I’d prefer that to take on more of the bass wave impact first. Then the fiber glass insulation can help reduce whatever is left over. I’m also going to try and rap duct work with insulation to cut down on resonance through there... is there any thing you suggest I do to my ceiling that’s relatively affordable? Am I headed in the right direction? I’d prefer to stick with a drop ceiling as I love the quick and easy access for wiring.
Adding some insulation above the drop ceiling tiles will greatly reduce their potential to buzz/rattle and will also provide some sound dampening and bass trapping.
I have 2) sundown audio SA8V3's bridged on a crown xls 2500 . I'm listening. Thanks for the video
Good choice!
U used these on an Elac 3010, passive radiator , the whole sub is almost jumping at low frequency it doesn't happen with spikes, I'm not sure why, but at other normal range it does sounds cleaner.
The video mentions that the height was optimized as well in testing. I'm putting these on some custom subwoofers but I need to add a 3/4 inch "spacer" (for lack of a better word) between the feet and the base of the subwoofer because my cable connection will be at the bottom of the sub. Does adding that spacer (3/4 inch mdf "puck" the diameter of the soundpath feet) negatively affect the ability of the soundpath feet from doing its job?
It shouldn't have a negative effect as long as the SoundPath Isolation System is still between the subwoofer and the floor.
Will these make much difference on a floor with carpet? Received my SB-3000 this week and running it with my Yamaha YSP-5600 sound bar. It’s unbelievable!!
It really depends on how your room is interacting with the subwoofer output. If you hear windows and other things rattling , or it's bothering neighbors roommates, it will help. You can also return at no cost within 45 days if there's no improvement.
@@SVS_Sound Thanks. Will try them out. The SB-3000 sounds amazing! Can really feel the bass!👍
My subwoofer is on concrete. But I still get some rattles on the opposite side of the room. ???
My subwoofer makes a rattling sound at 35hz is there faulty in subwoofer or all subwoofers rattles at 35hz?
You should not be hearing a buzzing coming directly from the subwoofer though it is not uncommon for subwoofer output to cause things in the room to buzz at certain frequencies. If it's an SVS subwoofer, please contact our support team to dive deeper into the issue custservice@svsound.com.
@@SVS_Sound thanks but it's not am svs subwoofer its am edifier t5 sub
FYI Isoacoustics offer a similar product which I can wholeheartedly recommend. The have the Gaia or Orea which seek to decouple as well, but use calibrated a weight based loading system, which would be more effective than using this SVS system on other branded products (since the weight loading factor would change).
I actually like the floor shaking effect, this is why I love down firing subwoofers.
Exactly, my subs shake the staples outta my 1973 trailer. It adds a whole lotta excitement to the experience
My subwoofer Actually fires down word
Make a mesh cradle and suspend it with bungie chords?
Though the elastic chords might deteriorate over time
Not sure how well these will work for down firing subs maybe need an extra platform perhaps a granite slab with a couple of sets of these one to isolate slab from floor and one to isolate sub from slab .
Just bought these and they work like a dream. Thanks
Thanks for the feedback!
Not worried so much about things vibrating except the sub itself. My Dynamo 700 subs tend to "dance around" on the hardwood floor sometimes and I' keep having to put them back in place. They sound great... just a PITA.
This video is basically just an advertisement for rubber subwoofer/LFE feet.
And not to mention, they're absolutely useless if you have a downfiring sub.
@@HeretixAevum True that. These things cost $50 for some rubber feet too. You can achieve the same effect with a pad of high density closed cell foam for about $2 ... Unless you have a downfiring sub of course. I have my sub on a concrete floor covered with linoleum tiles. The room has rattles and buzzes so I watched this to see what I could do about that, as per the clickbait title. This information was useless to me, those neat little shoes for my sub would not help and they really didn't cover anything else that my system can do to remedy this problem.
This is an infomercial.
informative/ commercial yes
my washing machine vibrates if my sybwoofer plays.
i got some yesterday and i like them
Hi SVS!😊 I'm currently on the market for purchasing a small compact subwoofer for my apartment. I've considered many brands, but landed on SVS. I'm currently looking at the SVS SB-1000, but my question is. Are you guys planing on making a similar sub, but with a 10" driver, to make the cabinet even smaller? Cheers,
Hi Kristoffer - No immediate plans for a smaller 10-inch driver subwoofer. SB-1000 will remain our most compact model for the near future.
So the rattled on the walls and ceilings are from the energy of the sub bouncing the audio waves around causing unwanted noise. Interesting
Technically speaking that I don't think so that every one should need a extra pair of rubber pads to decouple the subwoofer and its low frequencies from the ground especially floors with carpets on it and on cemented floors. Because in my experience I already listened different types of subs some with bass reflex, some with passive radiator, and some build with the tech of air suspension which you also called them as sealed for a long enough. These types of floors doesn't digest enough frequencies which have been reproduce by the subwoofer itself so in this case you will still get a decent amount of power driven out to you as deep as the subwoofer can handle the acoustics upto.
("MAY BE RECOMMENDED FOR HARD WOOD SURFACES AS THEY RESIST SOME LEVEL OF FREQUENCIES")
Lol imagine complaing about your expensive speakers being too loud.
So what can I do about a down firing Subwoofer?
All down-firing SVS subwoofers come standard with the SoundPath Subwoofer Isolation System. They will also work with other brand models as long as there is enough clearance for full excursion and the screw thread size works.
Legendary? I've never heard of or seen either of you before.
Fair enough, it was a bad joke.
Should try this with my desktop's sound system. There's literally a joist under the floor right where my desk setup is and a double joist under the wall the desk is in front of... The bass vibrations basically go though the floor into the joints and into the center beam of the house much to my mother's announce.
It should definitely help with the energy transference in your scenario. There is a 45 day risk free trial so you could test and return at no cost if there is no noticeable difference.
@@SVS_Sound I tried it with a scrap peace of hard foam it definitely makes a difference in both the thump of the bass traveling though the beams and less revirb resulting in cleaner bass. So I'll definitely be doing something more permanent.
Put poster putty under every picture frame, lamp and decoration that rattles!
Great tip, that definitely helps!
❤️❤️❤️❤️
Been doing this since my first home theater I setup for my Mom in 9th grade!!!!

They need they ass beat
Tried the feet. The sub walked two feet during one movie. Using thick Velcro on solid feet now.
Spikes seem to work great.
There are many solutions so they dont dig into your wooden or marble floors. I was thinking since the tip of spike makes minimal contact with floor it's a positive thing. I honestly dont know much about It though. And am learning by hearing y'alls input. Thanks!
@@HermesTrismegistes369 I would think that would couple the sub to the floor and increase the transmission. Good for those of us who have a room where we like the effect.
A $1000 sub should come with them. Then you pay $100 for 8. Im glad i got carpet and all klipsch speakers with 2 12inch subwoofers. Sounds amazing. No rattling or nothing.
I got a dual setup with pb2000s coupled with the sound patch. Still got threats from neighbours that they would call the cops on me. They live three floors down under me. 😂 I stopped the party right then and there. 😂
I have 3 SVS subs, 2 PC-13 ultras, and 1 PB-12 NSD. What I did was use the shipping foam and then cut plywood to cover the foam and put the subs on top of those. The PB-12 NSD has a mechanics dolly under it. Do you think these pads would work better than what I did? I live in a manufactured home and you know what kind of rumble that is, hole house, neighboorhood, I also have bass traps and acoustic foam all around the room. I'd be glad to try them out if you think it would be better than what I have now. Fantastic Subs I must say...
Thanks! Given the research we put into the materials and testing, it would almost certainly have a positive impact on reducing rumble and rattle you have vs. the current solutions. My recommendation would be to take advantage of the SVS 45-Day trial and install on 1 of the subwoofers to see the effects and then return at no cost or add to the other 2 subwoofers if you notice major improvement.
@@SVS_Sound Yeah, I don't think I'd be able to notice anything with only 1 set of pads. I wouldn't want to turn the other two off because it wouldn't be the same sound I know, and love. I like my music at concert levels, lol... Thank you SVS Keep up the Damn good work!
These sound path feet do sweet F all to stop room rattle
I built a pair of subwoofer platforms with four tennis balls each sandwiched between 1-inch thick boards. I used a door hole saw to recess the tennis balls and hold them in place. This greatly reduced the mechanical transfer from my subs to the floor and seems to tighten the bass sound considerably.
My neighbors were not happy about my lows vibrating their lady parts each time I played music. Finally they can sleep and no more wet dreams. I took the concept and design my own pads, but thanks for sharing
Happy to help reduce your neighbor's lady parts vibrations. lol
My subs (dual pb3000's) are in my basement on Cement. I still get lots of vibration and rattle. Bass throughout the upstairs. I have figured there's not much I can about it. Yes?
You may want to try the SoundPath Isolation System with the 45-Day trial, and if they don't help mitigate some of the vibrations, send them back at no cost. Beyond that, there are things you can do to soundproof the basement, like insulation between the floors or installing other dampening materials,
I have these on carpet/concrete and it definitely helps reduce the vibrations and rattles.
How do I keep my windows from rattling?
I have/had this problem on both my windows in my listening. Older windows that rattled like crazy. Of course not everyone can do what I did. I drove in 2 machine screw inserts into my window frames on the left and right side. Then I took a oak 1X2 and made clearance holes for a threaded knob and a stud on each end for the inserts. Now I have a cross member running across my window. Then I made a wedge from a of a block of wood to press against the glass in the center of the window and this temporary cross member and that puts the glass under pressure and prevents rattles. I can put both up in a few minutes for a longer and/or higher volume listening session. I figured when it is time to sell it, I'll fill the holes with a wood plug and stain to match. You may be to able to the inserts next to the window but under pressure did not want the drywall anchors to pulling out. I find I need quite a bit of pressure against the window glass. Volume/frequency dependent of course. You can test this by just by putting pressure on the glass in the center with your thumb.
@@briansimmons5363 yeah I have the same problem as soon I push aganist the window the rattling stops. So I might have to do some mechanical work as well or just invest into better sealed windows
