My test: Group 31 battery roundup *round 1*

[TaylorFade 671]

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.

And that was 12 total caps right, you call a brick 2 banks of six? Blue or black? I don't want to draw attention from the thread topic, but do want to clarify.

[TaylorFade 671]

Yeah, a brick is (12) total. So, (2) banks.

And actually... that testing was done on two banks of (7) so reserve was lower. I had them bussed in 7's so we could do 17.5v testing on the D5 and Zero.

Thanks taylorfade now I know what I need to do,and thanks for the demo a STC am the black guy that walk up to you and shook your hand.

Man that is one loud ass truck you got now I know how 155+ on music feels like.You know I won 1st place in my class 751-1500 stock 152.3.

[TeamHT 1975]

LOL @ 2,000 watt amps

Those JB's were a nice surprise. A little disappointed in the Nendo but what can you say, lol

[Bass520 63]

This one should be part of the test reikken high output 3209 group 31.

[TeamHT 1975]

Mail it to Taylor then
