I thought it was 2 Front, 2 Side, 2 Rear, 1 Center, 1 Sub. I recently picked up a Harman Kardon AVR-525 7.1 receiver and it is great. I paid $495 for a factory reconditioned unit with a 2-year factory warranty. Check out
OneCall, that is where I got mine. I have AR speakers all around and a Harman Kardon 12" Sub
