Axiom Home Page Forums General Discussion Home Theater EP-600 Review thread.

That reminds me of a third reason people buy multiple subs... it's hard to predict exactly what you are going to need, so one good strategy is to buy something less than a big monster sub (but still get something that will go deep into the bass) and add a second one if the first one turns out to be a bit too small but otherwise good.

Note that this only makes sense if you start with a fairly capable sub in the first place. Two cheap subs do not equal one good sub -- even 500 cheap subs will not be able to reproduce the really low notes.
