    I just bought a Yamaha 5640. I was hooking it up with some old speakers I had lying around in the attic as the rear/center (from an old Fisher Pro Logic decoder). These speakers have an impedence of 4 OHM. The manual says I should use 8 OHM speakers for the rear and center. Can I do something here? Or just junk these speakers and buy new ones? The receiver cleaned up all my Home Theatre fund [​IMG]

    2 channels, I'd say it will probably be ok....

    Try it, the reciever should go into standby mode or shut off if it truly does not like it.

    Thanks John. I will try it. My Front speakers are 8 OHM. Just the rear and center are 4 OHM. Would this work?

    If you don't turn the volume way up, you can get away with 4 ohm speakers.

    If you connect two four ohm speakers in series (amp plus terminal to one speaker +, that speaker - to the other speaker +, the other speaker - back to the amp -) for each affected channel, the effective impedance will be 8 ohms and you will be fine.
