Budget musical sub: sealed or vented design....

Dear Phasecorrect; ANY sub in an apt. is just begging to piss off those near your unit.(Above/ below / beside) BASS is the only thing they will hear,most likely. If you can hear it; they can hear it. Like the subs in those mini trucks; It is louder outside the truck than it is inside the truck.(Same for an apt--it excites the 2x4's ect.) Otherwise all those guys would be deaf.

SVS really makes some high quality subs.But as George said they maybe to much for your neighbors.Good luck!

I read an article recently that said masonry is a terrific sound insulator for subwoofers. So if your floors/walls are concrete, it may not be as bad as you think. The article also mentioned that subs that fire forward are more neighbor friendly (to those below you) than those that fire down.

Have you seen the Earthquake supernova 10"? Also, I've heard good things about the ACI Force.

REL Strata III...if that's no enough bass for you, buy two of them and run them as a stereo pair.

I realise apt living is not ideal for an audiophile...but hey...what are u gonna do?...at any rate...consenus is front firing is better suited?
