Krakin, are you some sort of mad scientist?

I would have replied earlier, but I was measuring the output of my amp with a yardstick . . .

What you hear is not the air pressure variation in itself

but what has drawn your attention

in the two streams of superimposed air pressure variations at your eardrums

An acoustic event has dimensions of Time, Tone, Loudness and Space

Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears,

thus no formula can achieve a definite effect for every listener.

Lmfao. Brad Schulke is hardly public anymore. He's in the doghouse.

Great testing Taylor, and we should all say thanks for taking a shit load of your time doing these test. Gives a lot to think and contemplate about the next batt purchase.

Thanks for the words, guys. And your insight, Ninja.

There were a couple of anomalies in this testing and a margin of error is difficult to predict in SPL testing like this, but if you consider the bulk of the data and assume a +/- .3dB margin of error on burps and +/- .5 on the music runs... things get put into perspective. It's difficult to eliminate ALL variables in SPL testing. But I try.

Also... a lot of people have asked me why I didn't include a brick of caps in the testing. Well, frankly it's because it would draw attention away from the results- because a brick of caps would skull drag any of these batts on burps. Including the bank used for the control. But for the sake of data, I did an amp roundup a couple years ago and I tested batts vs. caps. Batts were an Odyssey pc2150 (which is easily on par with the very best G31's) + an XS d5100 underhood. Here are those results. This is a traditional clamp NOT on peak/hold. Rise was ~ .9ohms.

AQ2200

- 2,538w @ 11.4v (batts)

- 3,365w @ 13v (caps)

DD M3a

- 3,657w @ 11.2v (batts)

- 4,088w @ 13v (caps)

RD D5

- 3,898w @ 11.1v (batts)

- 5,355w @ 13v (caps)

B2 Audio Zero5

- 4,052 @ 11.3v (batts)

- 5,355w @ 13v (caps)

About 1dB louder across the board. Batts don't want none.

i said it before and ill say it again. 3.3k out of the aq 2200?! thats plain crazy.

not to thread jack, but i'm going to have the AQ2200 on the AMM-1 within the week. i'm excited.

If you have any questions relating to nutrition, lifting, or health in general, feel free to give me a PM and I will give you straight forward advice with no BS involved.

1 ohm burps (average)...
NSB - 150.63
XS - 150.53
Juicebox - 150.43
Crescendo - 150.26
Energizer - 148.56

1 ohm music...
NSB - 148.5
XS Power - 148.4
Energizer - 148.4
Juicebox - 148.3
Crescendo - 148.0

.25 burps (average)...
NSB - 153.77
XS Power - 153.7
Energizer - 153.5
Juicebox - 153.0
Crescendo - N/A

nice test. Not sure how 153.77 is better then 153.7 - talk about splitting hairs LOL

with the exception of the one test at the top (the energizer) it seems like all the batts performed close to the same (within a few tenths of each other). Anyhow thanks for taking the time to test and post results! :)

and FYI: there is no specific "brand" that is a sore subject on this forum. I have no problem with any brand. My only problem is people trying to sell stuff or advertise (even indirectly) without permission. Any forum worth a damn will not let you do that either. Then when we politely ask you not to do it, if you want to act a fuckin' fool, then you get what you deserve. If you call all your fuck buddies to come in here and harrass the forum under the false pretense that i have a problem with "brand x" when i don't, then you will never be welcomed back. If you are a polite member who gets along with others, even if you make a mistake, you are all good....just don't be a DICK if we call you on it.

but again, that being said, thanks for the test. I know it had to take a while to do it and then upload the results.
