So my setup is 2.2 (two subwoofers) crossed at 100Hz (LR 48dB/Oct). I'm trying to minimize seat to seat sub-bass variation in 4 seats in total (4 measurement points).
Room layout and current subwoofer locations (red rectangles are subwoofers, all of them are on the floor, blue oval shape is listening area)
Amroc simulation of the room (Link: https://amcoustics.com/tools/amroc?l=354&w=481&h=244&r60=0.60)
Frequency response showing the variation between the different seats, the mode @48Hz (0,1,0) is completely minimized as expected from the placement of the subwoofers. The mode @ 36Hz (1,0,0) still show a lot of variation although the subwoofers are placed in different poles of the mode. I expected the mode at 60Hz to be minimized as well since it's (1,1,0) but there is still ~13 dB of variation.
The biggest issue is in the 90Hz to 100Hz region (1,1,1 and 0,2,0), Is there anything I could do about that without putting the subwoofers further in the room? and why there is so much variation at (1,0,0)?
Some useful reading for those that cannot keep up with the thread.
