GM, if you might still read this (a for a second time resurrected thread):
Might I ask how could one build an aperiodic w/ an F3 around 70-80 Hz (how-to regarding volume, stuffing and resistive vent size/construction)?
Regardless, it obviously can be shrunk quite a bit using ~aperiodic loading with the trade-off of course being a higher F3, etc..

Depends on which driver specs and what the final box Qt you want once room/whatever is accounted for, IOW you basically want to design an under damped sealed cab that when ported/damped = final Qt, so a quick FWIW/YMMV what I did was empirically make a ~1.0 Qt box, then vented it with the pioneer's Av = Sd, Fb = 1.56x Fs and damped to 'taste' to get an acoustic mid-bass roll off response for corner loading, separate sub system.
edit: Av = Sd was T/S, damp/stuff the vent; earlier, a true reflex Av = Fb in area, damp/stuff the box with tuning all done using the click test.

GM, nice simulated responses... and large box, a little less than the Onken tough. I was going perhaps the opposite way to EBS, small closed/aperiodic with high f3 (80) and several small subs below that.
I'll keep those files and I appreciate you sharing them,

Please excuse the off topic request but I'd appreciate any advice with my Altec midwoofer issues.Depends on which driver specs and what the final box Qt you want once room/whatever is accounted for
