I just bought a new Onkyo Receiver (TX-DS787) & wanted to know if I should use the Large or Small setting for my speaker setup. I currently have two RF-3s for the front, RC-3 for the center and two RS-3s for surround & Velodyne CT-120 for my sub. Im impressed with the sound quality in two-channel stereo but a little disappointed with full five-channel stereo. I think my sub crossover setting is not setup properly with my speaker size setting on the receiver. Any thoughts?
