Hi, my Onkyo receiver has required service twice in the past year. The service center (recommended by Onkyo) says the center channel died during the first outage, and I should have my center speaker checked. After the receiver died again, I took in the old center channel, a 8 ohm Synergy C1, and they said the ohm reading was low, and that I should replace it. I tested it on my multimeter at home and it registered 3.8 ohms. I just bought a new 8 ohm RP-250C and it registers 3.2 ohms. Should they be registering near 8 ohms? I'm testing by touching the leads to the respective black and red terminals on the units (not opening them up).
