Vintage speakers like mine, the crossovers were designed with L-Pads at mid-attenuation, which allowed boosting or cutting the mids relative to the woofer and boosting or cutting the highs relative to the mids. I just used a sound meter and a pro’s ears to adjust mine very successfully. You could adjust mine to your space/ears very happily in your space I am sure.
This was actually before stereo, the great mono designs which were often subsequently doubled in spaces when stereo occurred.
They anticipated unknown spaces to range from dull to bright, and for personal taste, in your case personal needs also.
Very few modern speakers allow adjustments, a shame IMO.

You might want to think about a good graphic equalizer which would allow more specific attenuation (boost or cut) than tone controls. Perhaps a used one with return privilege’s.
Then, mess/learn how to use it with your existing speakers first, next consider what speakers you could thus have some specific control of.
Oh yeah, I found my inexpensive sound level meter and test cd with specific tracks of 1/3 octave frequencies great tools. I realized, I don’t need a pro/accurately adjusted one, just answers of relativity of each adjacent band
tripod, seated ear height, listening position
there are others, this test cd has 29 selectable frequency bands
