I currently have a Cambridge FPS2000 setup, which would be fine, except for the fact that the rear channel appears to be fried!<br> <br> (The rear channels crackle whenever sound is played... the fronts sound fine, but the rears are horrible.. snap crackle pop! I've tried switching the cables, and the problem follows the channel... so I know the speakers are fine, and assuming the channel is fried. Any other ideas of things to check?)<br> <br> So, for $150 or less, which 4 speaker setup would you reccomend? Easy wall mounting (like the FPS 2000) is a big plus. Primarily used for games.
