I'm not a new member, just a returning one, but I wasn't sure where to put this particular question. I don't seem to be getting as much out of my subwoofer as I should. I have an SVS PB12-Plus connected to a Pioneer SC-05. I've used the automatic set-up and rechecked everything in the manual mode as well. I've even used my sound level meter. It just doesn't seem to have the punch that it should. Now, I am using 2 cables with a connector to make the run from the receiver to the sub. At the time I did this, I wasn't able to find a single length for the run. Could that be the problem? Would a single cable of the same length be better? Maybe that has no bearing on it, but I'm at a loss right now. Any help would be appreciated.
