After most of the summer & fall, we have began to enjoy our HT system again and of course, once again, I want to calibrate, calibrate, calibrate to get the most out of everything. I've noticed that upon calibration, I find my sub, a PB2+, really doesn't give us much ooomph until it is around 15db hot over and above everything else. We typically listen to our system in the -32 to -35 range on the RX-V1 which is plenty loud and I still find myself messing around with the sub to get more low end emphasis...... and I feel I should be getting more than I am. My previous sub was a 20-39PC that was updated to the "i" driver and digital amp and it was a very solid performer. A real room shaker and you could feel it in your chest. The pb2+ is sitting in the same location, corner loaded, but I feel we are missing something as, from all reports, this should be a monster that "tears through the house and takes our breath".... and it does when I have it calibrated 15-20 db hot......... This week, I am gonna begin to move it around the room and get it away from its current location. My alternative location is about 8 feet from the corner, to the side of the entertainment center. Before I start moving this behemoth, what do some of yall think?
