Yes all speakers are spl calibrated for my seating position, all 3 speakers are using the same 12 gauge wire, and I am not using any additional power amps for any of the channels (yet).

That being said, is there any easy way of testing if I have a defective center? I mean I have done the ear test where I listen to each tweeter and driver to see if sound is coming out - but maybe I have a different issue? I mean short of ordering a second VP150 for testing/comparison?
