The HK website only shows figures for 8ohm speakers and the back of the receiver only mentions 8ohm speakers. I hear that these have a lot of power but are they only good for 8 ohm speakers?
H/K has this info in the FAQ section on their website:
quote:
All Harman Kardon Audio/Video receivers can handle most 4 and 6 ohm speakers on the market today. However, there are some manufacturers' speakers that have a minimum impedance well below the 4 and 6 ohm nominal impedance. In this situation, the receiver will protect itself by going into standby mode. This will not damage the speakers or the electronics, but it is an indication that the speaker in question is not compatible with our receiver. Note: The continued use of the receiver with speakers that cause it to shut down can result in eventual failure of the receiver which is not covered by the warranty.
