Correct. FS 35 or under Qts .5 or greater should put you in the ballpark. Have you checked specs on Dayton subs on partsexpress? I'd guess they'd model pretty well.As I look, what specs should I be looking at that indicate that it may work in 4th order. Ive heard a coupld of times, if the sub works sealed it works in 4th order? Another forum said low Fs and high QTs?
