My girlfriend has bought a very expensive wall unit. She has a regular 32" TV and I just bought her a DVD player. The wall unit has 2 floorlevel cabinets with speaker cloth- presumably to house subs. She wants upgraded HT sound, but doesn't want to see any speakers or wire, so surrounds are not an option for her.

Two questions: would laying 22's on their sides in these sub cabinets work as L/R fronts- will the cabinet angle compensate for their unusual placement? If I add a center channel to this setup, would that help this compromised situation?
