I'd like to see this as well. I'm having trouble imagining it, though, based on things like this...

16 12's in an Astro doing 154, on almost 10k watts
1 15 on something like 5000 watts doing 147 ish
2 18's on 2500 watts at 148
2 15's on 2000 watts at 147
6 15 Treos on bunches of power at 148

These were all on my termlab, at various meets. I'm just having trouble coming to grips with the physics of a 10" woofer doing 150 db. A 15" woofer has over twice the cone area of a 10, so its Xmax would have to be huge.

Sure, Nate Munson did like 170 with a 10, but if I'm not mistaken, that was at some farily high frequency, before they changed the DBDrag rules to only allow up to 80 hz.

All that being said, I don't claim to know everything (not even close), so I'm not going to say that it can't be done. Several of you guys on here seem to be tuned in to the SPL world...what do you think it would take to get 150db out of a 10? I'm interested in specifics...box design, what 10, how much power, what car, what media (burp, tone, frequency), and how much other work would it take (electrical system, sound dampening, etc). If someone puts forth an idea that seems reasonable, maybe I'll put it together, and see what it can do.

For the sake of science, of course.
