I am looking to build a system using a Denon 3803 and Swans speakers. My question is whether that receiver will have any trouble running speakers where the nominal impedance is 4 ohms. I am looking at the following speakers for my theatre: Swan 6.1 BC for the front mains (8 ohms) Swan C3 BC for the center channel (8 ohms) Swan R3 BC for the surround speakers (4 ohms) I am worried that the surround speakers will be difficult for the receiver to drive and I don't want to damage the amp. I have limited knowledge of ohm ratings and the like as you can probably tell. Any help here would be greatly appreciated. Also, any general information or suggestions anyone might have regarding the above described setup would be appreciated. Thanks in advance for your time.
