I'll chime in with my speakers here. I have a set of Boston Acoustics and absolutely love them! I know, big surprise to anybody who has paid attention to my posts in the past.

Anyway, I forget what the actual model number of mine are (I think they're just called Digital MultiMedia) but they don't make them any longer anyway. However the Digital BA790 appears to be a very close match. I know they aren't full range down to 20Hz or anything, but I don't look to rattle the casements with my PC. As long as they sound clean and can play loud enough to dance with my girls when a favorite song comes on or for them to be able to watch a movie, I'm happy! Besides, they'll still play too loud if I need them to.
