OK. Anyone remember Drew A. Kaplan, and his hi fi stereo catalog of gear marketed under the name D.A.K. ?
Would have been back in the eighties and nineties. He had a lot of cool looking and some cool operating stuff. His catalogs read like a used car salesman on steroids.
Of the two things I ever purchased from D.A.K. one was a graphic equalizer with built in analyzer and “reference” microphone.
The idea was to set up the mic at your primary stereo listening point, turn on the analyzer function which included a pink (I think) noise generator. Then you would set the EQ adjustments to make the room flat. It wasn’t automatic but you usually only needed to do it once.
The problem was that with my entertainment system set to compensate for the room. It sounded dull and lifeless.
I would end up setting things for a smiley face scoop on the EQ sliders to make it sound to my liking.
So constant, or even manually adjusting a bass amp to compensate for the room probably wouldn’t work out too well for being heard in the mix. You usually want to go more for a frowny face (inverted scoop) so you have mids enhanced to cut through the mix.
Oh BTW, the other D.A.K. purchase I made was a bread machine. I actually liked it much better than the EQ box.
