Jeff - I have the 41 Pioneer speakers, previous generation, and they sound very good for Rock music. Not the last word in detail or transparency but I can't believe they sound this good for $90 delivered. The new model, the SP-BS22 is supposed to sound even better. These with decent receiver would be great for your application. My neighbor has the set with the center channel and sub and it sounds pretty good. They would be a good, inexpensive choice for a game room or HT.
I'm surprised by how loud they play and the bass output. IMO, they are in a class above the other speakers in this price range (Polk, Infinity, etc.). I even like them better than the little Paradigm Atom speakers. For the money, they are a bargain.
