Thanks Wayne. Cool, I believe ya, makes sense, as long as I'm not feeding it a big sine wave at box resonance, air speed should be fine.

I was just suprised my the amount of huffing when I played the M252's at real low in a box tuned to 32hz.

Anyway, those M252's sound pretty good, not quite as quick (read punchy) as the EV 15TRXB's they replaced (the M252's have a heavier cone and stiffer suspension), but a few Db more efficient and can take a heck of a lot more punishment.

Question, How does one filter out all below resonance information? would I have to get an active crossover? or would I have to make a real steep passive filter.

Thanks,
Danny
