If you have a sub made for a 3ft^3 box in 1ft^3, it's not efficiency, it's just peaky and overdamped. haha
































































































how long will it take Bill to catch on that I'm messing with him? Call in your bets, please.

I might have you design me a box Bill. How much you charge?

Not necessarily just high sensitivity woofers but any woofer. A proper enclosure can increase the efficiency of your bass output for instance a 1cube box may produce a score of 122 db but uses 460 watts. Where as a 3 cube box could produce the same score using only 200 watts. Increasing the efficiency of the woofer but no increasing the sensitivity.

higher sensitivity subwoofers in enclosures with higher gain at or near their tuned frequencies, you mean?

:dance

Efficiency still applies when you start getting into enclosures there are a couple of companies making very high efficiency woofers Hifonics makes one in the Olympus subs and i think CV has a newer version.

I didn't mean to be too fussy about it. It's just a really common mix-up with the two terms. The (mechanical) efficiency for the typical speaker is about 5% (work produced versus power applied) whereas the sensitivity.. well, that's what he wants. It's a shame Cerwin Vega isn't still making those old subs that had a 92dB sens. rating. I liked those things. I used those in my old Festiva with great success.

The more sensitive the sub is, the more output you'll get per watt of power applied. The issue that you may run into though is that by demanding a 15" sub with a high sensitivity, it's probably going to have some weird T/S specs for Fs, BL, and so forth, depending on the motor design used to get that high of a sensitivity.
Its close enough for use simpleton's smartass! :tough
