I am an original owner of the rm3000 sub sat system . I luv them so much that I just bought 4 more used rm 2000 sats and a rm2500 center channel to use in a home theater setup.

Can someone tell me the impedance of these speakers. I seem to remember that is 6 ohm. If so I need to change some settings in my amp.

Thanx for the help !!!

    Take a VOM and check the impedance at the terminals. Then multiply that by 1.3.......(rudamentary math, but its gets you close to the nominal impedance)

    VOM Reading Nominal Impedance

    3 Ohms 4 Ohms

    6 Ohms 8 Ohms

    However, I have found a specific example...such as my RT-16's that the manual says is 8 Ohms Nominal, but the reading I get is 3 Ohms on my mulitmeter.........so take it for what its worth..

    By the way, I have been questioning impedance on the forum as well. So I had to google it, and this is what I came up with....take a read....

    Thanx for the info.

    I was hoping that someone from polk could reply with the impedance that the speaker is rated for.

    Hello,
    In checking the product brochure, for the RM3000 system the impedance was given as "compatible with 8 Ohm outputs". I don't believe there any serious dips in the RM2000's impedance curve to cause concern. You should be able to leave the receiver's setting at the higher position. Most opinions seem to indicate that a receiver will sound better, less compressed, at the higher impedance setting. I suppose it depends upon what is actually happening when the selector is set at the lower position.
    As to being able to measure the DC resistance, of the satellite, I don't believe that would be possible. It has a built-in high pass filter, blocking a DC measurement.
    I hope this is helpful.
    Regards, Ken
