Help EQing the subwoofer

[Marcus Aseth]

Seems like you have a few options... Add some bass absorption, adjust the level/gain on the sub, try a few other house curves to flatten out the bass response a bit... Or any combination of the above... EQ/DSP alone may not get you over the room response especially in the sub bass and bass frequencies... Does that sub have its own EQ? If it does try to flatten those peaks that... Might be faster than trying several convolution filters... It might point the way to go with the filters if you choose to run you sub flat and do all the room correction with convolution...

more absorption is not an option in this room, unfortunately, but this subwoofer has a "Room Gain Compensation" setting with 4 settings, currently I have it off but this image below shows the effect of those settings.
I might try and set it to 25Hz which I assume should kill those peaks, and then match the curve to the new measured rolloff and do the convolution filter again, sounds reasonable? I'm afraid it might be too much, I might be doing more harm than good to the sound

No harm in trying all 4 settings... Give yourself a little time to let each setting settle into your ear/brain... And then, by all means match your room curve to what sounds the best to you... Its not always about what looks good on the charts, its how it sounds to you that matters...

after the convolution filter there was a dip I didn't liked so I've added a 2dB gain peak filter from Equalizer APO, is it ok to do so on top of the convolution? I have no idea how this things interact, but the measurement after looked alright

I personally don't like adding gain, only cuts... The only thing you may run into with your peak filter is some amount of pre-ringing, which you shouldn't see with the above inversion method... I couldn't say if it would be audible though... Just something you will have to try and see err listen... Again, you are trying to get to _The Sound You Like_ not a pretty graph...
