I moved all my equipment downstairs and ran all new wires for the speakers. I went from 16awg(?) to 12 awg. The subwoofer already had RG6 run through the wall and to a faceplate. I was unable to replace this section of wire because of spray foam and heater vents, so I just used a RG6 barrel connector on the one piece and extended the cable to the receiver. There was probably about 6' of rg6 already there, and about 20' of what I added. I also used compression connections at the ends of the cable I ran.
After all this, I re-ran the Audyssey setup (twice), and everything is working. The problem I am running into is that it does not seem like there's the same amount of bass after the setup, and Audyssey is saying the sw is 22'...which I read is not really the distance, but because of the circuitry, it is based on time than distance. I also checked the crossover points and raised them a little to 80hz, instead of 70hz.
In any case, should an extension like I did affect the performance of the subwoofer? Should I replace the entire length with a single run?
