It's cool. I'm a bit of an old school PG buff so my nerd alert went off.
Essentially they still move air but just doing so by rotating (sorta like a fan) instead of moving in and out.

Well yeah, I know what I mean... but it certainly did come out incorrect.

LAwl.

I just can't see how that could produce bass lol. Do they sound good? What about box sizes and power? Sorry I know nothing about these.

Box size for these is about 3 cubic feet sealed and should handle 300 watts IIRC. They sound very good from 10-50hz. Not an SPL woofer or anything close to it but they sound very nice.

Worked well in bandpass too IIRC.

Anybody from this site remember Geolomon's quest to make his own? Extremely large, custom made one?

There transient responce is very bad and gets worse as you go higher, maybe a better HT sub? Polo..
