Here are different variations with the subwoofer in the right corner without filters or eq.
Subwoofer set to THX (no volume control), then set to an 85 target and a 75 target at a -12dB FS sweep.

Subwoofer set to THX at a 85dB target at -20dB FS. This is exactly the level I would listen to similar with DVE and a 75dB target at -30dB FS.
Did it work? What could I do now?

edit: Can't I improve lower extention also by stacking them on eachother?
