I am trying to calibrate an SVS PB2-ISD. This is the first sub I have ever had so I am struggling with the calibration.
I have the Avia disc, and I calibrated it to 80db at reference taking into account the required adjestment for a Radio Shack SPL meter.
I guess I just expected to get slammed in the chest.
Don't get me wrong, the sub is awesome, but I am wondering if I have misconfigured it.
I have it set to 20Hz with one port plug in. For movies I have it running 2db hot. The gain is set at about 1/3.
One thing I noticed in using the Avia disc was during test that starts at about 200Hz (or something of the like). The sub seemed to roll of at around 40Hz. I made some crossover adjustments and then was able to hear it down to about 28Hz. The volume seemed to really drop off below 30Hz. I kind of expected to feel it all the way down to 20Hz and below.
Does anyone have any suggestions?
I would really appreciate any help.
Thanks in advance.
