@smaarch1....Since you mentioned the thought....
Try the short 14' wall first....all it requires is the time and effort.
A small sub might do the trick in the meanwhile while you consider your next move, gear or locale-wise. A small unit ought to keep the neighbors at bay but allow you to make the B&Ws' livable yet....
Go take you ears on a tour for the next speaker pair if you opt to stay condo'd....Another space opens a whole new can of acoustics to fend with...and a whole new set of bills with new numbers to pay....and pay...and etc. ;)
And then there's the gear for a new space, which starts the whole thing all over again....don't let enthusiasm cause crazie...*G*

when you hear the full capabilities of the Bose Wave Radio."
Oh, come on, MC....no need to get rude...jez....:(
