Which sub is better for audio

buy *two* vmps larger subs for that money & have *real* bass...

Vandersteen 2Wq for sure ... very musical. Go listen for yourself.

when wouldn't you use a sub for audio? back vibrator maybe?

hi neato, i'm not into h-t, but lotsa guys are. accurate bass isn't as critical in h-t applications...

Assuming you mean a sub primarily for MUSIC (vs. home theatre), then I also highly recommend the Rel Strata III (which is a bass extender--you mains still get full range signal, and you set the sub to come in just under the mains' low range) or the Vandersteen 2Wq (traditional 80hz cut-off).
