I was just wondering, a lot of people here seem to go to a lot of big comps, and I have one 15" sub on one amp, and I was wondering if anyone actually paid attention, or happened to notice how hard they've seen a setup like that hit, I'm topped out at 149.4 dB so far, I wanna hit 150 without a dynamat kit (which is my next step), but I just want to see what anyone else is hitting with one 15

About 140-141 with one 15 550WRMS and no dynamat.
That'll soon change. [img]smile.gif[/img]

JohnnyToronto off here was hitting about 144 on the new termlab mics with 1 15 and 2 d2's.. which is a tad over 150

I hit about 141.5 on the new termlabs with 1 L7 and 1 1500D.. which is around a 147-148

I was hitting about 146-148 DB with 2 MTX 6500D amps and one 15" Inhuman DVC, double stacked magnet sub. It was in the back of a Jimmy, with a big ported box tuned down to about 35 Hz

What's up with the incongruencies of the new mic's now that the scores seem lower?
Did we have some bad mic technology that caused inaccuracy until we had these new mics? Sounds rather funny to me.

it's all relative. you have to remember that everyone needs to make their own product identicle in any part of the country, so the more advanced they get the more precise we can get assume our score is. but then again two differnt mics is two differnt mics. We shall see if db drags idea works properly, i think only time will tell.

The new dbdrag mics can be from 4-8 db's lower than the old ones.. (depending on the score)

^ That doesn't entirely answer my question as to WHY, but that's fine. Decibels are a man made measurement, it's as fallible as we are.
