I am not totally satified with sound of my sub.
It seems to me that it calls too much attention and that it does not melt very well with the rest of the system.
I have set the crossover for all satellites to 120Hz and the LPF of LFE to 120Hz either.
Gain is at 25% and sub level is -4,5 dB.
While it does tremendous shaking of the sofa to its left, the sound does not seem natural and too muddy.
Attached a drawing of the room and a rendering. Ceiling is 9 feet.
The rendering is somewhat old. The coffee table with the lamp on the south wall on the right of the sofa, is not there anymore. The sub is in its place.
Any suggestion is welcome.
