Very well done, and thoroughly presented! Gotta love THE TRUTH 👌

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!

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.

I like the cut of this guy's jib EMF Audio just earned my money for next summer's build

Great video EMF! Definitely the #1 source for car audio knowledge

Thank you for a truthful test video, i appreciate your honesty and EMF as a top of the line quality product that will last.

So awesome to see how the audio world is all interconnected and keep the truthout there.

Its funny, nothing from rockville in the comments section. They should rate the k9's at 500rms and call it a day.

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.

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.

Rockville cares more about damage control then quality control..

Awesome, Rockville look like a bunch of scammers with those lame test vids.

As I’ve said before, I really love your no bullshit approach to speakers.

Thanks for posting this video! I think your saying what everyone else is thinking! Looking forward to seeing the next one!

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!!

Nice video, was worth the wait, keep those video’s coming

Yes yes yes!!! I’ve been waiting since your comment on the rockville videos

Wow, finally someone who is a true authority in car audio equipment. Thank you for making the video!

Thank you for explaining. I can never think another way for them to realize.

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.

Can’t wait for part 2. Great video.

They probably put a sundown dust cap on one of their own subwoofer

I guess they need to make a V3

Getting more and more interested in placing an order. Your speakers are amazing.

When I saw this video come up in my KZfaq feed, I smiled real big.

I am. So glad you stepped in on this issue.

Good video. Can’t wait to see the Rockville test.

Great vid bud keep up the great work

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

Man been waiting on this since I saw you in the Rockville comments

Spot on bro!.... now this test you done very straight, direct, and to the point.... nothing hidden... very nice... 2 thumbs up man 👍👍😎

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

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 agree with EXO test and EMF Audio test 📐🛠

Oh man Sean got eem! Can’t wait to see part 2... great job on the video

I love the ending around the work bench XD throwing some calming shade

you definitely know what your doing! i just subscribed to the channel. cant wait for your next video

Thank you for the great video. Consumers need to have the subwoofer police around to keep everyone honest.

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

Great video EMF. Hopefully all the confused people will watch this video and understand the truth. You are awesome!!! Looks like one beautiful sub

Oh hells yeah I've been waiting for this

Very professional & informative video. Addressed everything very well and in depth 👍

How about doing a dyno on the Rockville amps they used?

I am So happy you made this video to shut them up LOVE TECH STUFF TUESDAYS #EMFAUDIO 👍👍

Informative & understandable great job as always EMF audio

Looking forward to part 2. I like how you try to simplify things. kook !

Well done, this was a pretty choice opportunity to promote the Lowballer.

Awesome video! Love Tech Tuesdays!

Arriving by Tuesday lol. You flashed that fast. Anyways great video man. Never watched an entire video of this length on KZfaq. Very educational and interesting. Keep up the good work

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

Staying tuned till nxt week

So awesome. Can't wait til part 2.

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

EMF FTW! Honest and factual, with soild products worth every penny. Tons of value.

🎤Mic dropped from emf audio

Been waiting on this.

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!!!

Awesome video. Thanks for your time and experience 👍

Thank you for your time and consideration

I was already subscribed. But I get what you're putting down brother! See you next week 😁

So I have a dual 1ohm sub and when I wire it like that it’s half ohm like .7

Am ok playing America bass subs all day 😄..am a Jamaican so 8-10hr and barely warm in a sealed box with 3 15’

Got another video idea Example. I have a subwoofer rated for 800 rms Amp I have rated 1000 rms (CES rated amp) How do u dial the amp back accurately to 800 watts. What tools do u use?

Thanks for keeping it real keep bringing that bass.

This was an excellent video.

Awesome video. Can you test Rockville amplifier 5 Channel.

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 😊

I would like you to get one of the Rockville motors and build it to the specs needed to take the rms it’s supposed to or close

As always great video man :D

I can't believe they tried to make there subs look as good as a sa sub.

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.

EMF you just got me as a new customer!!!

Oh I can’t wait until next Tuesday!! 👍🏻

Is that 12k cea rated? 😁

Nice video 👌. When I watched the will it blow video the fist thing I thought was they were distorting the SA.

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 👍

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.

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.

Oh yeah Big Thumbs up. Keep up the great work

What about cea 2031 for speakers?

Killer job! Intrigued me to looking into ur products. Apparently Rockville has there own watts lol

very good vid keep up the great work

Best ending hahah 😂😂 sit down in a workshop, with a calm voice 😂😂

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.

Shots fired!! Good job man, exposing their lies with facts. The work bench part had me rolling.

That 3015 Watt spike on the Rockville's test (minute 6.09) says it all.

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.

Great video to bring some sense to this crazy mess that Rockville has gotten themselves into. Keep the truth coming.

From your experience, whats the best way to test a subwoofer to determine its power handling?

I don’t know if u can tell me what’s the best 12” subs and amps to buy

Awe man. Rockville, y'all had an opportunity to make a credible name for yourselves with this 'version 2' sub that a lot of ppl were excited about. Instead you cast shade on eXo. eXo inst some nub that has never owned a decent sub. The man can hold his own in the spl world. And damn, trying to make sundown's sa subs appear subpar to elevate your sub. Good analysis EMF, and as always good vid.

I never doubted EXO's Rockville Video but thanks to EMF Audio for backing it up! Well done!

legendary!! thankyou EMF! xx

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.

Question. Rockford Fosgate uses a CEA 2031 rating for their subwoofers RMS output. My question is what does the CEA 2031 rating mean? Could you maybe explain that in a future video?

Awesome job good test

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.)

I can't wait for next Tuesday

Thank you for making this video.
