Yamaha RX-V665
Will the Yamaha RX-V665 be compatible with my Bose speakers rated at 10-200 watts per chanel and 4-8 ohms or will they blow?
Depends on the Bose speakers you have. 201 or 301 will likely blow. Some systems have a feedback sensor that will protect the speakers from blowing by sensing too much power. If you have 901's. You have no chance of blowing them. I've had my 301's (which were originally rated for 45 watts per channel) for over 35 years and have pumped a 60 watt per channel system through them the entire time. When they can't handle the power, the systems shuts down output to the speakers until the volume is turned down. I've been very lucky. If you don't pump the entire 200 watts through them, you should be all right. What exactly do you do with 200 watts unless it's outdoors?
