Just got my 2 SVS powered 20-39 PC Plus_ subs after MUCH internal, and some external debate. I can only say "wow" in several ways. These things sound incredible, I was debating the 20-39 ultras, but 650.00 bucks more for 2, I went the step above the PCI's but not the ultras. I can't imagine wanting more than these plus subs. Anyhow, the problem is these things are huge!!! My girl is not home yet, she has been speaking of alergies. I told her on the phone, I have 2 "super air cleaners/purifiers" they are there, RIGHT when you enter the room! They are big, black, and round, and say SVS on them, cause I care so much about her. How long do you think I can pull that off??
