I have Sony SS-MICN Center channel speaker (150 W) that I would like to use with my Sony STR-DE945 Receiver (110 W for center channel). The receiver documentation states that the rear and center speakers have to be 8 ohms or more. The SS-MICN (an ES model) turns out to be 6 ohms. Is there any way I can use this speaker in my system or did I make a big mistake obtaining it? The receiver documentation say that it has a protection system that may shut the system down. Is there any way to increase the impedance of the speaker? I understand that adding resistors will not work. Should I worry about it at all? Is there a danger to harming the system? One idea I had would be to put another speaker in series with this one to increase the impedance. The receiver is against a wall that has a garage on the other side. I could mount a raw speaker in the garage so it wouldn’t interfere with the sound in the home theater room. Would adding a 4-ohm speaker increase the impedance to an acceptable level? What wattage speaker should I get? I would really like to use this speaker and am trying to find a way. If anyone can come up with an answer, it will be in this foum.
