Part 3: Rockville Punisher vs EMF Audio Lowballer, what specs do you look for when choosing a sub? 

You haven't been doing 5k burps, you've been using a 5k amp. Additionally, I do 31,000 watt burps on YOLO's, that doesn't mean they'll take it for a period of time. Burp power means nothing. But in regards to claiming a certain power based on a voltage and current clamp, refer to the clamp testing of the amp used in this video. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uBYuyzB-Ku0.html You'll notice it shows voltage and amperage which give VA, the same as what you're referring to. In that particular instance it shows 9,162 VA where the actual power when taking into account phase angle is 7,999 watts. Different frequencies, different volume levels, different impedances, etc. will have a different phase angle, so it's not a set percentage it will be different either. In the case of the 7500 there is a 13% difference in those numbers where on the 4000 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-y-8k3_VoEZY.html playing the same sub in the same box at the same frequency there is a 23% difference.

Speaking of K9's.... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-9N8aqpuXldU.html

The tricky part is when bias is involved, staged failures. Rockville started doing a video series based on that and 2 or 3 subs in they quit because it backfired on them hard.

And that's why I don't care for Rockville products, companies like Rockville won't be one of the top notch companies that everyone uses or looks for that serious about car audio in the future but one of the cheaper brands that will be better than factory components they're not looking at Long term but the Newer companies like yourself will be around forever and that's what everyone wants

Part 2 comes before part 3, it's already been up.

@@EMFAudio 😂🤦‍♂️oh yeh... If i had brains I'd be dangerous

The lowballer v1's are only 150 right now on emf's store. I paid just under that for my dd audio redline 212 (300 watt) and while that sub is absolutely amazing I don't doubt you can get far more spl from the lowballer for the same price.

There is more different than that, but those have been gone for probably 5 years, maybe 6.

The specs are only as good as they're given, give the wrong specs, they mean nothing.

@@EMFAudio I hear ya. No disputes there.

Exo did a video on the destroyer

If the punisher couldnt handle it I doubt the rest of their subs would handle what they say as well.

I’ve got a destroyer on a HD3000.1 and I love the combo. 3 batteries, duel 0 gauge wiring to the amps, big 3, on a 2.7cu ft box at 34htz. 👌🏾

Remember, their website said 1 minute on a tone so it will take it all day. It didn't do that, so it won't take it all day, it failed in seconds. You're asking if it will take 1,000 watts RMS when it's rated for 2,800 watts RMS, think about that.

Meanwhile, if you watched Part 2 (this is part 3) you'd know the sub being tested is 750 watts. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--AjpgZF9dL8.html The 900 watt revision 1 that is on the website as a current model (the original is listed under discontinued) is what you're quoting. And fun fact, the original will take 900 watts, even though it's not rated for it.

Why not just start with something good to start with that costs the same money in the end?

@@EMFAudio id never buy one new

Nearly a month later I'm still waiting on them to do something with the first one....

@@EMFAudio 😳🤦‍♂️

Sound quality is EXTREMELY difficult to come across in a video.

@@EMFAudio lol! I just want to know what U think and why? I cant get watts through my laptop either but Im workn on it. P.s. id start the Wall of Shame with subs of that stature and never take them down

Regardless of which is which, the description says it will take a tone for 1 minute and will therefore take that power all day. There is more than 30 seconds in a day.

Correct parameters would help too, and correct weight on the box, and correct item descriptions.

Then watch part 1 and part 2 where you find out everything else Rockville lied about.

a rockville show car ,hahahahah thats a good one

Part 2 came before part 1, it's right on the channel.

That amp may be pushing some dirty power ? I have 2 Rockville Punishers on a Dbcomp5 and Punish them myself with no smoke or DB drops..been extremely happy with the subs. Dirty power can blow subs quickly. Not saying for sure that was your problem, but seeing you're promoting EMF products then maybe the 750 rms sub is built for or tested on that power source 🤔 Either way just wanted to clarify what experiences I have had with my Rockville Punisher 12s and amplifier.

The reason why you aren’t seeing smoke is because your using a rockville amp, they don’t put out rated majority of the time so your subs could take so much more power before they actually start to smoke

@@michael8356 thats hilarious assuming emf amp is dirty power but the rockville is clean 😂 had me in the first half not gonna lie

A lot of them stem from not designing product in house, going to a build house and getting whatever they offer and going off their specs which might be before broken in or just flat out inaccurate.

@@EMFAudio Damn that's no good! And in this case with the power ratings REALLY bad😬

XD

They're on the product page.

Your box has to be REALLY wrong to cause damage, within 10% in any direction it may just not perform as well as it could otherwise. I've also done a video on how box modeling software is wrong. It's really best to go with what the manufacturer states and the specs don't matter, if you're using it in a daily application.

@@EMFAudio yea...but in this case Rockville doesn't even know the specs for the correct box :). I saw your box software vid, been awhile tho

Double rated power? You won't see it because it won't do it. Maybe 30 seconds, not a full minute.

@@EMFAudio Boobs And Explosions Remember? Hahaha

No, that's not the way it is. Heat cycling is actually what WEAKENS glue. But yes, between every power test it was cooled.

@@EMFAudio yes, many cheap woofers have inexpensive adhesives that aren't fully cured until heated, once the coils warm up a few times it will fully cure the adhesive. Yesssss

The subs you saw perform just fine, were they playing on a big amp or playing with showing real power? There is a very big difference there.

You wouldn't be the first, won't be the last.

in your car you have impedance rise, so you probably never come to 1400 rms so they could last a bit longer,hahaha

@@trollslayer8260 it only lasts cause you under power the sub, that sub is never going to see 1000 rms more like 300 to 500

purple headed yogurt slinger with playing music you get impedance rise, so the sub gets way less power,thats why your subs last, if you want the give that sub thd rated power of 1400 rms, you need a way bigger amp and then the subs blow like you see in the video

purple headed yogurt slinger clamping only tells you how much the amp puts out, playing music the amp never puts out 2800

They can do whatever they want, I don't have to let them do anything.

When was the last time you listened to a resistor?

@@EMFAudio i wasnt meaning disrespect i was just saying that the DB comp4 and DB comp5 both put out over rated power on the dyno at 1% THD ive never encountered anything from EMF audio but i have watched a ton of reviews some good some not so good ive been doing car audio in my shop and competing for 15 plus years so im not just talking gibberish here i spend alotta free time watching bench testing of different brands and different series rockville rates thier stuff off the wall crazy but they make a few products that arent too bad just saying

Already sent it back 2 weeks ago, the cause of failure is "undetermined" still, despite seeing it fail below rated power 2 weeks ago.

EMF Audio I hope you’ll share your experience with their customer service once you get the replacement. I’d also be curious as to if the TS parameters on the replacement are closer to what they claim. I doubt they would be. In fact, I’d be curious if they were the same as the sub you tested for that matter.

We didn't point at a catalog and make a lower bid offer. We actually design our own products, and test our own products, and make sure they have accurate specs and ratings. It takes time to develop a good product. I obviously think it's not too bad of light because I showed real results regardless of what they were, because I have confidence and pride in our products. If we rushed products to market we'd sell some garbage too.

@@EMFAudio It's all good man but when I look at EMF I see the top of the line. Stuff I would have to seriously save for and would love to have, but then I see you down grading people that yes may not be 100% accurate and I get your products 100% are. I just feel like you/EMF audio should better then that. They for the most part tell you to run the CEA ratings not the RMS. Not everyone is gonna run a test tone for a certain amount of time to smoke there subs. I'm sure the sub however could handle dynamically or bass notes at 1400 rms and maybe I'm wrong but I know dynamically my K9s can take a 1000rms each which is the cea rated power. I also bought one of there amps it didnt last but they made it right and fix my problem within a week. To some maybe I sound dumb but I'm new to this and wanna learn the ends and outs but when you see people bashing someones products or what products people have, who does that help may even turn people away from the car audio seen bc it overwhelms them. My comment was dickish no doubt, but you don't see Tesla comparing there vehicles to Smart Cars. All I'm trying to say is take the high road and stop worrying about only Rockville, bc you and I both know there are plenty of Manufacturers who lie about there numbers across the board but your not talking about any of them. Have a goodnight sir and thanks for taken the time to respond. Always 2 sides and points to a topic but doesn't mean they're either was wrong.

That would be a waste of money because I could never get my money back out of it, and would still be mediocre at best.

@@EMFAudio why wouldn't that be like a fun puzzle? Trying to make a Rockville woofer better then when you get the numbers of watts it should of hit get a paintent change the name and make it your own EMF sub just to rub it in Rockville face that you know how to make better woofers then they can.

I hope so! 🙂. It was very entertaining on the k9

Remember what happened last time when they did?

EMF Audio yeah they got drunk on camera and pretty much produced a video on why you should buy the Sundown Audio sub they were testing. As I recall you were also involved in that video calling them out on errors they either made or were about to make during testing. It was a absolute shit show for them which I’m sure they regret.

@@EMFAudio Nobody fires back like Rockville! They produce LIVE CLASSICS🤣

Okay so, you just showed us a sub that is cheaper than the lowballer AND handles the SAME power than the lowballer, then proceed to tell us to buy your sub... I would be happy to buy EMF if your sub was better or cheaper, you have proven thus far, that they screwed the specs up on the box and the website (along with every other company that sells subs) and that they have over rated their subs (along with every other company that sells subs).. but also that yours is no better, but for more $... .. go figure, just another salesman...

I definitely don't want to do their R&D when they won't fix the same problem over and over.

@@EMFAudio I get it. It would be cool to see you cut the cone off and see the carnage inside, though 👍

You can see what happened. The coil went slinky right off the former.The only "fix" for this is to rate the sub honestly. There's just only so much heat you can throw into a coil before it burns up. If you need to throw more heat into it you need to get into an 8 layer or larger diameter coil... both come at the expense of more MMS and larger gap which involves trading off efficiency. I'd bet that anything you could do with that motor as far as adding """cooling""" or using a higher quality coil would do no more than 10-15% increase in continuous power handling. Lowballer for example is a 2.5" coil, compare with Sundown SA, DD25XX, or even Alpine Type R which are all honestly rated at 700W or so, that's about the limit of true continuous power for that size coil. This is getting into the difference of power ratings of "hook it up to an amp rated for this and you'll probably be OK" vs. "it will withstand a sine wave at that much clamped power for several hours". And as far as I'm concerned Sean should get as many returns as he can and break them at or below rated power and create as many videos as possible. Companies that make dishonest power handling claims deserve everything they get; if your product isn't damn near indestructible at a given power level you shouldn't be printing that number in your marketing.
