It's time to expose the truth behind the popular Rockville K9 subwoofers! We all remember last year when the infamous version 1's came out, right? They ended up having lots of problems with defective voice coil enamel shedding off, then blowing smoke on rated power. So this big question is... Will the new K9 version 2's perform any better with improved glue, or will they get stinky all over again? After all, that 5,000 watt peak wattage rating makes me a little nervous! So let's find out shall we!? They supposedly improved and upgraded the 10", 12" and 15 inch woofers with bigger and better voice coils! But.... we'll be the best judge of that!!!
$100 Budget Subwoofers Tested:
W10K9D4 10" 3200w = 134.3 decibels @ 56hz (prefab box)
W12K9D4 12" 4000w = 141.9 db @ 40hz (custom ported)
W15K9D2 15" 5000w = 140.3 db @ 40hz (prefab box)

Thanks for watching, everyone!
Who wants to win a FREE 15" subwoofer!?!?
Simply leave a comment explaining why you'd like to have it... and you're GOLDEN!!! Even though it may be an overrated sub, FREE IS STILL FUN RIGHT?!?!?! :D
Hello EXO just about to get my first car and would love to have a sub in it but I can’t afford one. I’ve been watching your videos for a very long time and your very interesting and I enjoy your videos. Please pic me it would make my day and I won’t be able to thank you enough!!!
Looking for a budget 15" for girlfriends car. That wont see a whole lot of power.
Exo I would love to have this sub for a competition we are promoting at my job but hope u have great day and maybe you will come to Oklahoma soon have seen like every one of ur vids keep up good work can't wait to see ur 18's running again
Damn voice text, sorry for reposting, but I sounded an idiot, anyways my lady was involved in a pressure cooker explosion, so I had to pay both are bills, so I've been looking for a budget sub for her, she has been supportive of my bass addiction I would love to put a little bump in her trunk, without feeling too terrible if she blows it. Your channel is so awesome and your personality kicks ass, can't wait to see your next build.
I would love to have a sub becouse i am a broke teen who wants some good bass
This is one of the best, most detailed videos I've seen from EXO! The amount of time, effort, devotion and the ending result are nothing short of EPIC! Thanks for working with me on the collab, next time I'll leave the SPL stuff to the pro :-)
I loved this video...to really see what these subs are about...def way overrated ... EXO ur the man
I agree
@Williston Audio Labs are rockville v2 subs still worth the money tho? compared to other brands at 120$ range
You had a good video also
I was going to buy the destroyer, lucky I stopped myself!
Rockville life expectancy is measured in seconds. Good stuff.
EXO...MY MAN....thanks for using the SMD AMM-1!! I didn't even know you had one. :D If you need anything let me know. Great video by the way. :)
It's a great tool! Thanks for checking out the video 👍 Love what you've been doing lately!!!
my fav 2 audio guys
my two favorite guys EXOcontralto and meade916 all about BASS,REVIEW.. im from philippines
2 of my fav audio dudes are friends. The world is aligning again!
It's like watching Greek gods conversating
I truly love the basshead community bc everybody is so nice to eachother and everyone entertains eachother with their unique setups
They must have accidentally put an extra zero on the peak rating. Lol
The zero button sticks sometimes! 😆
More gain on the amp!
I was getting ready to say the last zero was actually a decimal 120.0 watts
Its amazing what a zero can do ...
Rockville. Filling our landfills one subwoofer at a time.
badlands chugs reference?
Not really. You may devise a re-cone, per say send it over to EMF Audio.
@@ruikazane5123 EMF audio are the best.
@@ruikazane5123 old cone and coil would still make it to our landfills
@@maincharacter2677 I would go PSI before EMF. Focal also has some styles of recone kits.
17:00 wtf man 12 hours? I wonder how bad is it to live with a 12 hour long earthquake in your house
That sub doesn't quake, it trimmers.
I broke in my L7s using 30hz sine wave powered to roughly 1.5 inch excursion for 24 hours...got plenty of use out of them for years loved those subs.
@@MadClowdz You don't have to break in subs. You can play them normally and they will just break in themselves naturally. No need to baby them in the beginning, not gonna hurt them.
@@BurningDownUrHouse more like quivers lol
Depends on the amplifier too, high end amplifiers like Amcron have really good damping control to better protect speakers, if you're just using a cheap car amp it's never going to control a speaker and take care of your speaker! You are right about amplifier power ratings, most pro speaker manufacturers reccomend an amplifier to be double the speaker rating so you just run the amplifier at a steady rate, dc, clipped amplifier is the biggest killer of speakers rather than over power!
The voice coil being out of the gap too long is what burns coils not clipping. The voice coil has to stay in the gap for heat dissipation. Hook a voice coil directly open air and it will instantly be smoked. Just physics that's all
So it's pretty much just a 200 Watt RMS speaker labeled as a 1,000 watt.
Yup, a fancy door stop... 😁
Its basically a cheap Chinese subwoofer claiming its able to do 12k watts and is barely able to do 50 watts without blowing out
...kit... reminds me of your mom
@@kitcat2559 sundown subwoofers are great and made in China.
I'd say not even 5:1, more like 10:1... When you name your products to ride the wave of a tried and true manufacturer like Rockford Fosgate those are the shit that happens. So stay away from those Rockville, useless as a rock in your shoe, like Dracula to the cross.
you did a great job showing what these subs can do and what they can't do. You even kept a positive attitude about the misinformation in the paperwork and let us know that they would still make a really good sub if you just dial it down some. Thank you for these honest videos. I enjoy everything you are doing
Brother, that was a very insightful video. You've really impressed me with the simple yet technically educated way you answer questions that we bass heads sometimes don't know how to ask. I recently blew a Hertz 12 HX 300 D that I'd been saving for the past 12 years...sad to say. I have 2 and only 1 blew in a shared enclosure. In South Africa these things cost an arm and a leg. I now at least have more insight as to why it may have blown. I had been playing them for about a year, when my car's electronics began to go haywire. Gonna have to look for someone to fix the fucker without demanding my entire salary. Thanks again.
Love your work, in my teenage years I was the go to guy for car audio hook up, my dad was a car electrician, so I learned a lot from him, now that I have a 17yr old driving, we started adding upgraded sound to his civic, we’ve replaced stock speakers with JBLs, and I’ve been passing on the knowledge to him and he is now helping his buddies with their sound systems with my tools and knowledge, now he’s saving up for bass with the tips his friends give him, Once again, thanks for all your content!!
2 years late, but nice story man. Did he end up getting the upgrade?
12 hour break in. Your neighbors must love you
I have always figured, cheap subs, you cut their rms in half.
For some you have to cut 10 times.
Cut rms in half then cut in half again for cheap shit an some expensive shit
yep
I like that
So they are a 500W RMS sub. Excellent testing and proving what they will actually handle, EXO. Either Rockville is trying to slip these things by to the consumer or their manufacturers screwed them over big time.
Thanks for the video! I'll never buy Rockville's now... shady marketing is a bad thing.
JL
The amps aren't bad but even on those they hook that limiter to it that shuts it off way before clipping.
@@magicyeti9256 JL don't mess around. Their subs are incredible for SQ and SPL.
Turd 🤣🤣🤣
@@donalddluckerii3147 true that but who got JL audio money to spend on subs or amps...😬
Finally my dude is back. Lol. Good to see ya bro.
Man am I so glad I decided to go with two 12" Skar Audio D2's instead of Crockville's
I'm using one of skars 10" d2. Could not be happier. Glad I chose it over Rockville
SKAR is good. Sundown, massive and SoundQubed are awesome SPL subs. I'm more of a sq guy, so I'm running the Image Dynamics IDQ12v4
Yeah I was very disappointed in rockville's 15-in woofer. I contacted the company to try to get any information from them about building the box that would work for it. They wouldn't give me any info at all. So I gave away their sub. I'm now sporting a skar evl 18 in a custom 10 cubic foot slot port enclosure in an avalanche and I couldn't be more happier. Their sub is nothing but voice coil incense stick.
That’s some sick photography / filmography you’ve got going on! What a great video.
5 times longer than 10 seconds !! 😂😂😂
Like my sex life....sigh....
Dude I fucking lmao
Lmfaooo
Never thought you'd still be making videos... Been watching your stuff since the early 2010's. Keep it bangin, brother!
So the bottom line I got from this is that Rockville is fine as long as you keep the power down. No problem. Would still sound great.
EXO just gave some one a flat tire tossing those screws out on the side of the road when he pulled that sub out the prefab box 😂
your enthusiasm makes me so happy. LOL Great video bro, I must say I would love to see how this sub would perform with some PSI soft parts.
The Exo Master Tech Lives!!! Peaple actually like watching you man!!! Welcome Back!!! 😜🤠
It’s amazing how well a shitty speaker will do in a proper built box. Thank you for your content I’ve learned so much by watching your videos
It’s been a while dude! The community missed you!
Ikr 😂
Pretty sure you should give out free KFC to anyone that likes your comment.
Do a review of the new rockville destroyer. keep up the good work exo cant wait to see your new build 👍
Should be called the destroyeD
Know the worst part of all?
People are still going to buy these.
Purchase away. They are fine subs if you double up on them and don't buy into their bullshit specs.( Which are all over the cheap audio market. ) If your on a budget they foot the bill nicely. I personally love my JL 10" with the JL 500w amp but not everyone can afford that so these are a nice cheaper alternative as long as your careful.
This man acting like jl the shit now ::: FUTURE IS NOW OLD MAN
@@qj3780 JL is still top of line even to this day.
@@qj3780 If you are looking for a bullet resistant amplifier, JL make some of the best amplifiers on the market for different price points, and they back them by a warranty. You are more likely to cook a subwoofer than you are an amplifier, so it makes more sense to spend on the amplifier and save money on decent cheap subwoofers.
My K9'S sound pretty damn good,I have them married to a Rockville db16 monoblock class d amplifier and they sound pretty badass and they do vibrate my 2002 blazer like crazy,I have no issues at all with my setup and I do pound them and still no issues.
You’ve come a long way in your video content …… great work!! For bass heads: matching the wattage output and speaker aren’t important (“just turn the gain down”), but for the best S/N ratio, matching is key.
EXO really stepped it up on this video. I haven't watched in a while but with quality like this I'll be back.
Most annoying neighbour of the year award goes to *drumroll* EXOcontralto!
Haters gonna hate
Naw mine are the worse, they’re Cuban and they only play shit with the classic reggaeton beat on legit concert equipment that seriously rattles the cul de sac lol. Sometimes for days in a row during the week, but regardless weekends are mandatorily everyday.
Just an annoying person in general lol
@@gizmo3714 I was going to say the same thing. Dude seems like a tweaker from hell.
I win this lmao I have a 1.5 acre lot and I hold monthly demo derbies in my backyard while blasting music through JBL concert Towers
Wouldn't have expected this from a speaker company in this day and age, wow.
Great job dude :)
This isnt a speaker company. Its a scam.
Disappointing.. But there are better options out there for the budget bass head. I just got a 10" from Philips for 12.49€ on eBay and as soon as I get a box of it it'll slam!
Hows peanut dude that's a cute kitty!
Your overlay music is always superb man but I bet if you put a Rockville 5000 watt amp on them then they would accept that amount of power!
I have been watching you since the beginning! I love watching the progression from the van to the battery bank projects! Love your videos :D
Crackrockville audio. #can't stop smoking
Subbed! (No pun intended). Glad I came across this channel. You're a great host/content creator!!!
i’ve had my Rockville RVB12.1A 12” for over 8 months on full hertz and output, very impressed by it
sitting in my car laughing when the truck in front of me with a Rockville sticker on it thinking about the Memphis subwoofers in my trunk running at 900watts rms eatch...
Omg youre so cool. Like damn....so cool
Exo, Could you get your hands on the Soundqubed HDS2 sub series? Would love to see a professional performance review on that budget line. UA-camrs vote with the thumbs up (or down) button. Thanks for your work!
Hey I bought a 10 inch rockville 2000 watt. Sub. Last november I had it on a 3000 watt amp but I split the power to 1500 watts and it out performed my 12 inch subs until the amp burned up on me so now I have it on a 1000 watt amp and it still pounds hacrder than my 12 inch subs and I am using it as a mid sub maybe the 10 inch subs are more better maybe you can test those out and see what you can come up with I bought it from Amazon. It is a K6 series 4ohm and I do have it wired at. 4 ohm . but keep it up with out your opinion or testing today's subs we as a consumer would lose out of a lot of money.
Mine are still bumping loud af. Rockville sent me the V2 and I installed them on my second car. both sets are bumping loud AF without issues.
I prefer terminals if they arent junk!!
same
Rockville has released a new subwoofer called the destroyer, they have 300 oz magnets and look really nice but who knows how long it will last
My massive audio hippo xl is better than the destroyer
I could probably vouch for a lot of people we really do Miss watching your videos
You claim. Watching some disheveled bum tell me about audio is nowhere near my priority list.
@@markmalasics8413hmmmm... then tell me why you clicked on this video?? seems to me that you liked what you seen but then wanted to be the dick of the day and commented hahah you can say what you say but your words are trash kinda like your christmas videos you got on your page lol!
Ok so def won't be buying anything from Rockville anytime soon 😨 thanks for all the work you put in to keep us informed EXO. 👌🏼
Who is here after the announcement of Rockvilles lawsuit? Just recanting my comments to find where i called it .
They're getting a lawsuit? Serves them right honestly.
These remind me of the cheapo Rockford Fosgates with there R on the Subs.
Renegade!
Omg lol so if you want a chance to be able to play this you should probably run at 100 Watts RMS and maybe you might hear it LOL without it blowing. Thanks for the chance EXO
Great video! I was going to pull the trigger on a 12”, and just put 500 watts on it. Hell no! I’ll keep looking!
I love the cat in the sub box. My lil guy loves subwoofer boxes as well. I really appreciate all you do for us and the community. Thank you.
Absolutely the most in-depth review/expose of a brand I have ever seen! amazing work EXO!
Saved my time and money ty guyz #1 in my sound book...😁
I just bought some Rockville subs and played them on a 8 hour car ride they have really improved since then
Who doesn't want throw a couple coils through your truck lid ! LET THE BASS BOUNCE
I need a New Boat Anchor Rockville 15in speaker Would be perfect!!!!
Haha expensive anchor but it does not have any other use
15" sub with a 3" voice coil and 30lb weight....? Good for somewhere under 1000w RMS. Not rocket science.
Indeed
18:42 That fade! I thought your garage door was closing on your car! Hahaha
I love how animated you are! You are such a gem.
Coca
Why don't you face the speaker to the back of the car instead of the front? From my experience it's better to face it to the back.
Its an SQ build.
Why don't you test the newest speaker from them Rockville Destroyers that's what I want to see
I bet it’s can get low. The 13w7 Xmax is 32mm. The destroyer is 30mm rated at 2000 watt rms. If it can withstand the abuse then it’s worth $250
After what you've seen, I don't think that crap will handle 2K continuous.

Amazing amazing channel!! Been watching you for years Got my MECP back in 01 (showing my age) always knew how to perform standard installs on my own vehicles, your box building skills are very next level....also i never could understand how to calculate the math part (ohms law) but you break everything down in every video so your audience can understand..amazing work man, I can't say enough about what you do
Thankz for the detailed video was actually looking into on of these till i watched this video .
"Can you smell what the Rock is cookin?"
Lol
Why do we bass heads love watching subs move lolll
Lol😂
i don’t have the answer for you
how can you not love this dude, he´s such a wholesome guy. what an angel ♥
lol, came across this because i was in a market for some subs. Stay away from rockville.
Shout out too Big D probably 200-300 daily...
Damn. I wonder if the destroyer can handle the rated power lol good video.
Dbuilt Series doubt it lol 😂
The basket on the destroyer looks "VERY FAMILIAR" KML
Nope it cant destroyer is just as bad
Well nice to see there still the same old subwoofer
Glad I copped a 12" SKAR instead
Much better
Nowadays you get what you pay for. even though they're not well built and they're cheap my wife would love them if I bought them for her. Can't afford expensive things but proud of what twe have
Hey exo I love your videos man keep it up
You know, I had the same doubt. Good thing I was not upset by buying it, and by the way, the music played around minute 13 is swell!!
Play some more for the bleachers... and the oldies sitting here. You don't make me feel tired like other UA-camrs, you do great young man, keep it up. Great videos.
Push terminals? Ofcourse r u kidding me. Str8 wires look bad idc if the sub is pushing 8billion watts
I use crimp terminals under the nuts of the terminals. I dont use the "terminals" themselves. Its not a big deal.
He looks like the dude from the tuna fishing show...pinwheel boat
WICKED TUNA
Except Tyler is dipshit
Always had a bad feeling about these subs.
Notice when doing extended testing that the power goes down over time? That means resistance is going up 'cause the coil is heating up. I honestly didn't think it'd be that easy to see! Neat stuff! Just cut all the ratings for these subs in half and we'll probably be fine. Really sucks when companies overrate their stuff.
I would love it to install it in my girlfriend's car without her knowing and turn on a song and watch her reaction😂😂😂
Personally I dont NEED a sub
But i just got my 1st car, and my stepdad told me how he enjoys hooking up and wiring subs and making his own boxes and personally i feel like that would be an amazing bonding experience for me and him to do. But hey, good luck to all for this giveaway! Love and positivity!
I wouldn't put more than 500W on those, what ever they say do half
and thats how you get dissatisfaction and clipping. Always have headroom and make sure your amp never comes close to clipping.
@@Jeffdachefz How can it start clipping if you set up your amplifier to use around 500 watts instead of 1000 watts? Turning gain down doesn't make your amplifier to start clipping or break your subs and listening music at low levels doesn't break your subs either (your amplifier doesn't use 1000 watts of power even if the gain is set to that if you are listening at lower volume levels).
Hats off to you for attempting breaking it in at least 🤙
I’d say there’s not really a speaker that should be running at max for too long . Blurp is kinda the max . But if you’re looking for loud and length need more subs to distribute the work load
This video overheated every part of my phone somehow, but hey, at least i know not to go with Rockville
Hello EXO just about to get my first car and would love to have a sub in it but I can’t afford one. I’ve been watching your videos for a very long time and your very interesting and I enjoy your videos. Please pic me it would make my day and I won’t be able to thank you enough!!!
Them subs only can handle 200rms 500peak
he said he lowered it down from 500 so the cops wouldnt get called,
@@any1alive The frequency, not to power. He dropped it from 40 to 20.
That's funny because the video he made just over a year before this one he had put almost 1500 watts to this sub and hit over 130 db

I have three bd1 on a 2k and wow!
i like the bd2's FS is 26hz is very strange lol. my hifonics zrx 1800 makes my bd1's a lil toasty i do admit that's why i got 2 amps and hooked one audio pipe dual 4 with 1 skar evl dual 2 to make about .6 ohm and not wallop the speakers too hard (.9 ohm and 1.8 ohm in box readings)

I like how he played that Gucci Gucci for the full song. I like this guy
Their wiring guide is laugh able and really sew able for people who dont not know any better and goes to blow their amps. Their 1ohm guide is really puts a 4ohm load on the amplifier if I'm not mistaken correct me if I'm wrong.
that blown sub sun protection hat at 1:31 is fantastic
So, you have to realize that when I was a kid, even an early teenager in the late 90s, I used to be like Bruce. I would buy the cheap no-name subwoofers from Walmart and test them just to see how the junk would sound. I used to buy the even cheaper subs and boxes from flea markets to see how they would sound and while I was never truly blown away, they were all crap, let's admit it, but I have heard a few systems with those crap Walmart and flea market subs that could pound a little. Still, I wouldn't ever have taken them seriously for a system. When I built the system for my 1994 Ford Exploder (that was lifted and built mostly for performance with a supercharged 302W swap) I started with two Cerwin Vega 12s (which seriously pounded hard), but I ended up with two JL Audio 15s on a Kenwood 1200 watt 2 channel chrome amp with dual potentiometers. That thing would bounce a full Coke can 10' in the air at full volume on some Trick Daddy songs in a box that I built on my own. I was even trespassed from a Burger King because I was picking up a friend and playing my system in the parking lot. The manager called the cops and said that I was bouncing tongs across the table...😂😂😂 Man do I really miss those good old brand name subs. I'd really love to have a good set of those Cerwin Vega 12s, or even those JLs that I had. Fact is that you can't trust too many people or companies nowadays, so it's hard to find a good deal for a good price.
Hello Exo I just got my first car actually its not new. And I love good bass pumping all the time going to work its like coffee for me my whole morning is not complete with out hearing those bass from my favorite tunes. I work as a health aide and to be honest can't afford to set up my own system. If I would be blessed to be giving the chance to have those I would be truly great-full. I love watching your channel I learn a lot from it. Good luck and more videos to post.
Would love an upgrade to my sub, that handles more power. Thanks for all the information
Yeah, I know, 4 years late to the party, but I just bought two W15K9D4 Rockville subs for $140 a piece and I'm excited to get them. I had two Sundown SA12-D2 subs on a Sundown SAI-1750D amp and even in a cheap eBay box with two 12"x6" Aeroports they sounded great, but I need more air movement. Problem is that I don't yet know if the box will even fit in the trunk of my 128i BMW...😂😂😂 Size wise it SHOULD fit, but I don't know about getting the whole thing in there through the small opening, and of course my back seat doesnt go down.
I think it should be rated for 500rms it seems to do good with that no issues, maybe 800 or 1000 peak
Appreciate your videos ,I watched several of your box builds did my first build by following your video and you really make the video fun to watch not all scientific
