I like this a lot Dave. I considered one with a separate subwoofer too. This one works pretty well. I think it sounds as least as good as the built in speakers did on the PA800, maybe better, and it is plenty loud ( and clean ). I like that this one has an FM radio. I have a couple of the walmart type fm transmitters and a few MP3 players so I can play MP3s through it via the FM radio as well.
