For others to view as a point to compare with, here is my in-room curve of the bass response:
Test environment:
The sub is along the short wall to the left of the listening position, about a foot from the left wall, front baffle is about 6' from the front wall, and about 8' from the back wall. Both the SM65's were on and crossed at 80Hz. Audyssey dynamic EQ was enabled and volume on the AVR set to -29db. Measurement taken from RS digital SPL meter mounted on a tripod at the listening seat.
Test environment:
- RS Digital SPL Meter
- HT Shack's manual sub calibration worksheet
- HT Shack's test tones (14Hz to 111Hz, 1/6th octave)
- Denon 3312
- PB12-NSD sub
- Definitive Tech SM65 mains on 26" stands
- 16x18x9 room, with front stage centered along the long wall (~2600 cubic feet)
