ok who's been on both. how much diff have u seen. was the freq the same on both?

From what Moe has told me, and what I've experienced they are about 1.5db higher. (give or take .1 for various reasons)

I've always burped at 59hz. [img]graemlins/thumb.gif[/img]

I've always seen approx a 0.5 diff between the ac and termlab.. mainly because for dbdrag street the car is off and stock the car is on..

head to head test at the same time they were off by approx 0.3..

I dunno man. When I run idbl I usually go with the car off because I don't want to kill my alternator.

I do about a 147.3 on the TL with the car off and a 148.6 with the AC.

With the car on I have hit as high as 149.4 on the AC.

chris u on drugs? i know u've seen more than 0.5 db diff. i've even seen your scores from meter to meter.

I see a 1.5 diff as well

At the kingston show, I did a 145.6 on TL, 146.9 on A/C. Both with engine on, burping at 61Hz.

i tested my AX and Cecco's TL and his was louder by .3 db

kingston was messed. that was the only show where i gained nothing from TL to A/C.

richard how the heck did Cecco's meter read LOUDER than your A/C ?

Yuli when I first ever berped my kicker L7's
on john's Term lab I hit a 148.4 then a 148.2 with the car running car off 147.9
5 minutes later at that Mosport show I hit a 148.9
then a 148.8 on the AC both berps were at 54hz. hope this will help.
