I think this might be the case. The settings for the cable box are correct (Cox doesn't let you mess with them much)
I have double checked the wiring on several occasions, found no issues. In fact I have even tried using different brands of wire (my conclusion is that you should save your money and not by designer speaker wire). I have a cousin who is a rep for an electronics wholesaler that sells monster and can get it cheap. The mark up on that stuff at retail is incredible.
As for phasing and cancellation, the subs' phasing is fine, I checked it last night. Cancellation may be an issue, but not really a fixable one for astetic reasons. I must add that my old system, which was pioneer elite and infinity ( I also has a KSW 15, wish they still made them) didn't have similar problems. The room is pretty live with wooden floors and very little upholstered furniture and no heavy drapes.
The settings on the pre-amp are OK. I play with them quite often, trying to find that "SweetSpot" in the sound. As for night mode, it does eliminate some of the lower frequency boom when you don't want it, but that's about it from my observations.
So this leads me to three possible theories......
1. Ditch Cox and change to another provider, The only other option in my area is satellite.
2. Buy the bigger RC64, that is louder. (Not sure that this will make a huge impact though)
3. and this is the most expensive and far fetched idea... I am a church musician and our drummer is a sound guy by profession for several local cover bands. He seems to think that my system is hungry for power (eletricity). He seems to think that a 20 amp cicuit is not good enough to power my home theater and that I should have a circuit for the amp alone. Now all I have on this circuit is the TV (52" Toshiba DLP), DVD, Amp, Pre Amp, The sub, and a couple of lamps. I have never triggered a breaker so I am a little suspicious of this idea. but the concept does make a little sense.
Any thoughts, I appreciate all of your input.
