Very well done, and thoroughly presented! Gotta love THE TRUTH 👌
Hey exo im from south Africa and you inspired me to become a bass head even started my own channel would mean the world to me if you can check it out
It's funny of course I'm going to pick sides doesn't matter that I've been a fan of yours for years it's the matter of who's right and who's wrong and you're right and they're wrong keep pounding brother
Shout him out on your next video please! This guy needs the recognition.
Hell yes exo I had your back the whole time if you go to blowville videos you see I had your back
Hey EXO great videos man. Your very inspiring and honest which is what us fans love about you. Glad you have good friends to back you up. Forget these guys, remember you got an army of true bsaaheads behind you. Just keep up the good work and stay strong buddy.
i said it in Rockvilles comments and ill say it again. Exo and Bid d wiz are both honest and very capable in car audio!
So instead of Rockville admitting their bs they make up crap and try to discredit EXO and Big D!!Nice job..Smfh!!RATE YOUR PRODUCTS CORRECTLY ROCKVILLE!
Wrong. Make them products correctly!
Ancieto Maldonado Jr Then they better stop it until a serious person will get them at court, which won't be good
EXO is a bit off the wall.
Outstanding video sir. Put a nail in the coffin, this debate is finished. Rockville had an opportunity to step up and fix the issues and come back as a good affordable option, but just killed their own brand.. well said, sir. I'm a new fan.
Thank you for a truthful test video, i appreciate your honesty and EMF as a top of the line quality product that will last.
Great video EMF! Definitely the #1 source for car audio knowledge
Its funny, nothing from rockville in the comments section. They should rate the k9's at 500rms and call it a day.
right. all of the "off brand audio" should quit misleading people that don't know any better!
it should be rated as an entry level sub
So awesome to see how the audio world is all interconnected and keep the truthout there.
I like the cut of this guy's jib
EMF Audio just earned my money for next summer's build
I am so glad you stood up for EXO, he is such an amazing dude and does not deserve to be trashed. I have seen almost all his videos and know for a fact he knows what he is doing. I have been into speakers for almost 15 years now so i know thing or two but also learning and gaining more knowledge.
Yes yes yes!!! I’ve been waiting since your comment on the rockville videos
As I’ve said before, I really love your no bullshit approach to speakers.
Awesome, Rockville look like a bunch of scammers with those lame test vids.
They are look at their monitor speakers and the tube amplifier
Hey, we have the 8" K9 model on the mail, as soon as it arrives we will put it through our AES standardized test.
I have a feeling it won't pass.
Did you end up testing it? I don't see the video posted.
The thing that gets me is that rating their gear appropriately wouldn't cost them any sales. These are 15's for 110 shipped. Rating them at 500w or whatever they should be rated would not stop people at that price point.
Yeah that's all they have to do they don't need to lie to us.they dropped the wattage they would probably sell a whole bunch of subs.
I bet it would cost more sales than you think. Why not spend a little bit more for a Sundown E15 from www.emfcaraudio.com with a 2 year warranty? That's a similar class at that point, and it's got a 2" coil at that.
Well now that everyone has seen that the Rockville k9 isn’t what it is said to be I don’t think as many people will be interested in the entire Rockville products as much as they once used to be. See when they trick their customers that leaves a bad reputation on the whole brand and many people will end up moving on to quality brands that are true to what they say. Thanks EMF for your video on this!
Yes it would look at all the most sold amps on Amazon. Those 5000w MAXX ratings get more sales from noobs them honestly would get them from us.
They're rating it higher in my opinion so they can show up in more "narrow down" searches. Many people wouldn't expect a low end 500w sub to handle double it's rating for any length of time worth your money..... But they rated it higher, and it LOOKS durable with the basket and spider support bracket so it gets people to change their mind based on price.
Thank you for explaining. I can never think another way for them to realize.
Can’t wait for part 2. Great video.
nick newman nice profile pic. 12 all day!
Annon Omis you know it.. SEAHAWKS!!!
nick newman you live in WA/Seattle area? Looking for local bassheads lol
Annon Omis yeah, I am south of Seattle. I don’t currently have anything doing big numbers. I may be building something again soon. I just love watching what everyone is doing right now. Crazy.
nick newman I’m in the same boat man! I’m in Tacoma. Have a single Deaf Bonce apocalypse 12 on a Skar 1500 and a few other misc subs and Amps laying around
I love this video I have 2 Rockville k9 15s and I have to say this is the most understandable video of all the k9 videos. When you get your hands on the k9 PLEASE give us the real parameters. I don't want to destroy lol my k9s.
The K9 will probably blow while shipping.
@@81edition -🤣🤣🤣🤣🤣🤣🤣🤣🤣
Great video EMF. Hopefully all the confused people will watch this video and understand the truth. You are awesome!!! Looks like one beautiful sub
Lets see Rockville try to call you outour bigdwiz the way they have EXO...why they are going in on him is ridiculous and will hurt them in the long run... so glad to see someone of your caliber putting a stop to the confusion
Thanks for posting this video! I think your saying what everyone else is thinking! Looking forward to seeing the next one!
CEA 2006 is for amplifiers, but CEA 2031 is a measurement standard for drivers. I believe using a 6db crest factor pink noise. So you would approximately half the wattage for a continuous tone. Power is also just calculated as v^2 divided by nominal impedance.
Thank you for the great video. Consumers need to have the subwoofer police around to keep everyone honest.
Wow, finally someone who is a true authority in car audio equipment. Thank you for making the video!
Rockville cares more about damage control then quality control..
"than"
Shout out to EMF for keeping it real providing "true" real world information. Real numbers, real power handling, in real wold applications and just an honest no b.s video. The way it should be. Thanks for another great video EMF!!
Wouldnt be surprised at all if Rockville didnt respond to this video as they know they are caught. You would think any company that doesnt know exactly what they are talking would post a video lieing,misinforming the whole world,and more importantly the car audio community. They bit their own tongue and will not be able to come back from this unless they stop their cheap products saying they are something they are clearly not. Thankfully i have never bought nor would i ever want to be given any of their products,and never will including recommending them to anyone. Thanks for all the Tech Stuff Tuesday videos that properly inform all of us,keep them coming!!!
I suspect they will in fact have a response, possibly in the form of buying a Lowballer for "will it blow" trying to say we rigged it.
@@EMFAudio I think the bottom line is you just cant trust them at all,i didnt like any part of their videos as they seem to just side track from questions asked as i noticed they did to you as well. Ive Looked at alot of other companies that have CEA rated products and haven't found any that do shady ratings and comparisons like Rockville does. They may even come out and apologize for some of the things they said,and say they made a mistake,NOT. Who is gonna believe anything they say now???
I agree with EXO test and EMF Audio test 📐🛠
I love this guy he knows his shit calling out bullshit on all car audio pirate brands saving the hard working consumer lots of money on car audio purchases keep it up EMF your the best.
I hope you're going to be like Big D Wiz or Budget gems for woofers, calling out the posers. Be a good line of vids, fits your style of educational vids
Has he thought about it yet?
If it looks like a duck. Sounds like a duck. It must be clipped! This has got to be one of the best car audio videos I have ever seen
I second that. Best ever
They probably put a sundown dust cap on one of their own subwoofer
That would improve it how? Sundown melts down like a Rockville.
@@misterhat5823 what the hell you smoking lol
@@RTM459 The fumes from a melted Sundown.
@@misterhat5823 I've never owned one. But everything I've seen looks like they can take a beating. But I think they are definitely overhyped. They don't sound good at all. Used to for a sub to be good it had to eather hit really hard like a solobaric or solo x or get low but still sound good like an W7 . It seems like now people only care about the lowest pressure waves. Honestly I would rather own a rocksord fosgate t2 or mtx 9500 or w7 or if I wanted low a orian hcca.
@Code Ultimate LOL
Am ok playing America bass subs all day 😄..am a Jamaican so 8-10hr and barely warm in a sealed box with 3 15’
🎤Mic dropped from emf audio
Thanks for setting the truth free. I love EXOs videos and I also didn't see anything wrong with the test's preformed. I can't believe rockville would rather be" nicely " bashing other companies rather than fix obvious issues or just change the ratings on their products.
I can believe it, I think they went the wrong way about it. The best (but still bad) thing they could have done is shown how theirs doesn't fail under the same test. Obviously, that couldn't happen because it would fail.
Spot on bro!.... now this test you done very straight, direct, and to the point.... nothing hidden... very nice... 2 thumbs up man 👍👍😎
Cant wait to see part 2 lol...
Well done, this was a pretty choice opportunity to promote the Lowballer.
Best ending hahah 😂😂 sit down in a workshop, with a calm voice 😂😂
I have 2 sundown SA-12's that I've had for at least 5 years. For a couple years I had 2 of them being fed about 2500W RMS (67% over rated power) in my custom ported box tuned at 35hz and yet I never blew one. I have one now in a 1.1 cuft sealed enclosure and have been abusing the hell out of it, bottoming out the suspension with most of my tracks, i also accidentally gouged the foam surround in several spots and yet once I readjusted my amp for 750W RMS it still sounds great. I've run a -10db 40hz test tone for awhile with 500W+ RMS with no issues. I know I've clipped my subs for extended periods, pushed significantly more than rated power, but they keep on going. My SA-12'S are the original with dual 2ohm coils. I've always had them wired in parallel for 1ohm each, and 0.5 ohm when 2 were in my custom box. I have 2 APSM-1500 amps, nowadays I use 1 sub in the house for home theater and 1 in my car. Still going strong after these years.
The only other CEA/ANSI/CTA document pertaining to car audio speakers is this:
'Testing and Measurement Methods for Mobile Loudspeaker Systems (ANSI/CTA-2031 R-2014)
Audio Systems Standard/Bulletins
Defines test procedures for rating the performance and physical size of mobile loudspeakers, and requirements for reporting these characteristics'.
A big thumbs up 👍
Man been waiting on this since I saw you in the Rockville comments
Nice video, was worth the wait, keep those video’s coming
This is the difference in an honest company that uses actual rms ratings, and a company that wants to shit their consumers by highly over rating their products!! Awesome video, but I think we all knew exactly how it was going to go!! 😂
But in the Rockville video he specifically says they UNDERrate their subs because they know it can handle a little more.
Oh really!! 😂Im just getting back into the car audio world and just recently found out about your channel and products...kinda on a budget and went with 2 of their shallow mounts for a under seat box in my avalanche...1200 peak, 600 program, 300 rms...all these ratings I felt for sure it could handle a pioneer amp at 480 rms...1 lasted a total of 1min and only at 3/4 way to my max unclipped volume! I played the other sub for about a week before I decided that they needed to be returned! Label printed just got to find a UPS store nearby..Lesson learned!! When my money is right I will be hollering at you for a quality subwoofer that can handle what it says it can!
Thanks for this I watched there crap yesterday and thought the same thing as your saying. I've got 2 sundown e10s on double the power clean and they take it all day.
I bet , I had a zv3 15 on a shark 3500 , the amp does pretty much 3k , and the subs only rated for 1500rms , it acted like it wanted more power and murdered the trunk of my deville while doing so
Good video. Can’t wait to see the Rockville test.
Part 2 might be a rude awakening.
This video made me subscribe. Love it when people show the real truth That's the reason why we need people like exo and you real honest reviews no BS or jive talking just straight facts
EMF FTW! Honest and factual, with soild products worth every penny. Tons of value.
I guess they need to make a V3
That 3015 Watt spike on the Rockville's test (minute 6.09) says it all.
I bought 4 X15 Rockville K9, blew all 4 on day 1... so I went to LordOfBass and got all new soft parts to rebuild it and now it ACTUALLY does 1K RMS. I highly recommend just buying the subs for the motors and investing another $120 per sub in upgraded soft parts and you will get a very good sub at a decent price. My K9s are now just as loud if not louder than a Skar ZVX 15 for about $90 less. Which isn’t that much of a savings but I had the blown subs and figured I’d try to save them....
When I saw this video come up in my UA-cam feed, I smiled real big.
I am. So glad you stepped in on this issue.
I love the ending around the work bench XD throwing some calming shade
You’re spot on man. Rockville’s tests were bogus and even worse for the SA sub test. Plus if a company does make a quality product they certainly wouldn’t stoop as low as bagging on another companies product. This video was very enlightening.
Well, the method in which you talk about another product is key. If it's "it's just as bad as ours, so ours is just as good" is the wrong way. Physically showing differences like in the case of a genuine and knock-off is very different.
Thank you to you guys exposing these garbage audio companies. They look one way but perform another. I’ll spend my 199 and last for years.
I got to admit I hit the like button before I even watch the video because I've been following this for a while now and I'm just glad you made a response video can't wait to watch
I'm glad someone finally chimed in on this. Really liked the video. I'd like to see more people chime in on this just to prove that not EVERY sub will have the same problem as Rockvilles and that they have something shady going on
I don't know why some of these companies think audio customers are stupid haven't we got together to expose enough of them yet just give true ratings and they won't have problems even underrated is a wayyy better strategy... GREAT VIDEO (1 new subscriber)
Staying tuned till nxt week
Maan,look. EXO tested Rockville's subs and found that they are garbage, Big D Whiz did the same but got upset at viewers for saying that Rockville is trash and that nobody should ever buy them. If Rockville doesn't want the bad press then maybe they shouldn't make a bad product!
Getting more and more interested in placing an order. Your speakers are amazing.
Oh man Sean got eem! Can’t wait to see part 2... great job on the video
I never doubted EXO's Rockville Video but thanks to EMF Audio for backing it up! Well done!
8:10 - LOLOLOLOL!!!! That was awesome! That look on your face! I almost spit on my display hehehe...LOVED IT!
"So I guess you know what has to happen next" XD
PS:
Weird thing...The AC in my house is going out as well...AC guy should be here tomorrow though :P
Oh hells yeah I've been waiting for this
I am So happy you made this video to shut them up
LOVE TECH STUFF TUESDAYS #EMFAUDIO 👍👍
Arriving by Tuesday lol. You flashed that fast. Anyways great video man. Never watched an entire video of this length on UA-cam. Very educational and interesting. Keep up the good work
Thanks emf audio exo and everyone who taking the time to put out the truth. As a consumer I feel like we have a right to know. At first glance this is a killer looking sub. Oh well what could have been I guess
Glad someone set them straight it was so obvious to me I mean it was showing rms power on the screen that sub barely seen 600 more than a split second mainly 3 to 400 watts
Great video to bring some sense to this crazy mess that Rockville has gotten themselves into. Keep the truth coming.
I can't believe they tried to make there subs look as good as a sa sub.
I bought the k6 cuz I kept seeing negative comments on the k9s. I got 2 k6 12s on a audiopipe 1500.1. I've had em for about 4 months and they're still going strong
It's a 900 watt amp so.......
Yes at 2 ohms. And that enough. You're not gonna get a 1200 rms sub for 75 bucks. That's just crazy
@@josephsmith3195 It's a 900 watt amp in real life, that's the most you'll see clean out of it. I've tested one.
Dude your Sub woofers quality are way beyond for what you can get in the mainstream same price range. If I wanted to go big with quality I would buy you woofers hands down...until mine break I will upgrade when mine kick it, my damn kickers lol.
Greet video well made. Proof is full disclosure.
Been waiting on this.
Looking forward to part 2. I like how you try to simplify things. kook !
Great video. This also shows what thermal compression is, and that it is real. Playing loud and long will cause heat build-up, impedance will rise and SPL will decrease. A common mistake is to turn up the volume more to compensate, which will just dump more heat into the subwoofer and cause thermal damage.
Ricci does some great testing, here is an example where you can see how many dB's are lost due to thermal compression in an older SA-15D2
from 2012 (v1?): data-bass.com/#/systems/5b11db35a201f10004e39d79?_k=y1l0hq "Long Term Output Compression Magnitude Voltage Sweeps".
Shots fired!! Good job man, exposing their lies with facts. The work bench part had me rolling.
So awesome. Can't wait til part 2.
Oh I can’t wait until next Tuesday!! 👍🏻
700 watts rms sub only, it's still a good sub IF they would rate it CORRECTLY! come on Rockville, don't try pulling a power acoustic on us
Is it a 700 watt RMS sub? Or is it a 500 RMS sub? Man part 2 is going to be fun to record.
@@EMFAudio oh that'll be a good video lol
Even then how do I know it was designed with any care?
If a lowballer outpeforms it with a smaller coil...
Jacob Fuller is obsessive with his designing sending back tons of prototypes trying to get a perfect product. Many people consider the SA a perfect driver.
Sean seems to be similar taking the time to think out a cohesive product instead of trying to force a high RMS low cost product that doesn't even do that
@@Str8GasGenetics That's one of those things that comes out from experience and transparency. Both Jacob and I are very open about what we're doing, what's coming, and the thought behind it all. Giant companies aren't like that but that doesn't mean they don't make an honest product. Basically, if it's "too good to be true", you can pretty much ensure it's not.
@@EMFAudio absolutely true
That pisses me off trying to drag another company down because they make shit subwoofers. Good catch on them switching amps, I 've been running my ZV-5 on a 4000D for months and running hard not one issue. Screw Rockville aka crapville
I have never blown a sub running to much clean power
I normally don't like, subscribe and hit the notifications bell just because Im told to on the video BUT I just couldn't resist due to your calm all knowing voice at the end. On another note when I first heard of Rockville my immediate thought was, That shit must be junk. I didn't have proof then but now I see I was right.
Even their Rockville Destroyer has nothing on EMF Lowballers 😂
Informative & understandable great job as always EMF audio
You completely changed my opinion on the k9. That was done with facts honesty and proof thank you. I own three k610s I have no idea how or why but these three have outlasted two Alpine type r 15 s????? All subs parallel all dual 4 didn't touch settings same car blah blah blah ran with a soundstream dtr3400.1 250amp alt 0ga. All I'm saying is the k6 10 blows my mind even trund open the excursion in sealed box is honestly something to check out. Try one there 55 bucks I bought them to blow them up until they sounded amazing n keep taking the beating. Why didn't you buy a k9 and show us or a sundown?????
Damnit u got me part 2 sob lol nice one your gonna get me thinking about ordering some emfs to compare what's that coupon code for the impatient idiot?????
Lowballer 15's are on sale right now, no coupon codes.
I would love for u to get a k9 and see why it is so bad seems like a descent woofer from the outside looking in
Pay close attention to the calm talking at the end, don't just listen, watch closely.
Looks can be very deceiving.
I can't tell from the small picture but is that a 1911?
Recone a Rockville with an EMF and blow the magnet off the basket
Nice video 👌. When I watched the will it blow video the fist thing I thought was they were distorting the SA.
Thanks for the video, im looking fwd to a fair test to put this to bed. If Big D tests it i value his info, just a bonus to have exo and you confirm all this hype. Love the channel keep up the integrity.
that bit rate is gnarly at 32 bits - i presume because of db in relation to dynamics. i am not a bass head car audio guy, but loved the vid!
I have a pair of k6 Rockville subs;12 inch... And it is playing good for me.
Very professional & informative video. Addressed everything very well and in depth 👍
We dont mine if the wave file is clipping because the only thing that affect is that will sound distorted.When we play it in low volume sounds distorted but will not damage our sound signal.If we manage this clip wave not pass zero db line then its not a clipping sound as it sounds distorted because of the clipping wave line.(The shape of the wave is square.)
Exactly cea rated ha give me a real rms rating and sub should not blow great video 👍👍👍👍👍
Yup, they should have marketed it as a 500w RMS sub and everyone would be happy and it wouldn't be a surprise if you smoked one. (Don't tell me they blow at 500rms?) By duping people into sales with fake numbers they've screwed themselves, and screwed others who could have spent more and gotten a lasting product. Nothing wrong with cheap subs, but these guys totally over rated theirs by quite a bit and that's just not cool.
CEA rated their ass. Crap Estimated Ass
I think every brand should make a video showing THEIR SUBS taking the rated power, just to see who is true to the game!!!😎
From what I've seen, Rockville subs are just cheap rubbish and should be avoided.
look the K9 is loud 142 & 140Db is great actually for budget burps at SPL shows BUT on music they are 200-300watt rms subs max and yeah i'd say get a rockville destroyer on 600watts MAX if your into budget subs alby in my country Targa Audio has $135 15 inch sub of which has run 153DB off a single sub at 900watts Rms they also have the competition series of which a single 15 has done 158DB & 176.7DB best part these subs cost $175 meaning they are beasts for their price a opel corsa in our country is running 2x Targa comp 15's doing 162.5DB in a non walled setup.
here is 8 x 15's on only 4000 watts total cream pie-ing a windshield-> ua-cam.com/video/7OIWAIKQXtc/v-deo.html
Ahh man you're killing me ...I've gotta wait a whole week before we get to see part 2 ...it's gonna be a looonng week man !!!!😓😓😓😨😂...but I do feel a great sense of happiness knowing that the test will be performed properly with no bias ...I can't stop laughing because I know what's coming😂😀😀😂😃 roll on tech stuff Tuesday part 2 ... keep up the great work I love your vids big time and your brand is brilliant I can't wait to get my hands on some of it 👍👍👍👍👍God bless from across the pond here in the UK 😊
Thanks for keeping it real keep bringing that bass.
Great vid bud keep up the great work
