One other thing I found most amazing about the PAS is I had one situation where I had to place it... in the middle of the room. You take what you get and I was: yeah, like, ok, this is going to work... NOT.
But it did, better than I'd have bet. I was astonished at break running an iPod through that... the decay on the back of the speaker was not large at all. Behind the BACK of the speaker! LOL
