Correcting LF response using eq on subs only?

Trying to find a good solution for my problematic square bedroom system. Audyssey does a good job fixing the 10dB 50hz peak, but it also requires full range eq, which I’m not exactly a fan of, since it changes the timbre of my speakers.

Using eq on the sub only with an 80hz xover does not entirely eliminate the issue, since the high pass on the speakers is only 12dB/octave. To fully solve the issue via subwoofer eq only requires a 120hz xover. Obviously this doesn’t blend well, since I can almost localize a sub with an 80hz xover, and a 120hz xover is obviously worse. Has anyone had success with blending multiple subs and high xovers at 120hz or greater? What I’m considering is 3-4 subs around the room crossed at 120-140hz, and just using a mini DSP to eq them.

The other option is to simply run external amplification and a minidsp for each speaker, but that can get really expensive quickly. A nanoavr could solve the problem, but would cause me to lose atmos unfortunately.

Not getting why 12 dB/octave filtering has any effect on equalizing a 50 Hz peak… ?

What kind of EQ does the sub have? Parametric EQ should have no problem taking out a peak like that.
