Wow! Thanks guys. I should have checked back earlier. I do have a multi meter with an ohm setting I believe. I'm powering the speakers with a Marantz model 4140 amplifier. It says stereo 2 quadradial 4. It's older. it says it 400 watts. I'll try to include a photo. Im generally handy. I'm a carpenter and I work on vehicles, repair our appliances, but I've never been really proficient with electronics. I'll try to get back to you with those ohm readings asap. Thanks again. Fuzzy
