MRC (Meridian Room Correction) doesn't touch mid- and high-frequency information. All of the correction is done below 250Hz, where the wavelengths are large enough to benefit multiple listening seats.

Conventional wisdom would have you believe that maintaining signal purity through the playback hardware allows you to hear what's in the recording itself. Nothing could be further from the truth. When you listen to your system, more than 50% of what you're hearing is the room, not your speakers.

Your room is an audio processor, whether you like it or not. If you want to really hear what's on the recording and what your speakers actually sound like, then you have to minimize the room's unwanted contributions to the overall sound. Otherwise, the majority of what you're hearing is neither the recording nor your speakers. That's not my idea of "purity".

I was always told the way to attack room problems is with acoutical treatments
How do you target a piece of rigid fiberglass to to address a room resonance at 41.5Hz specifically? How do you stop absorbers or diffusers from touching the mid and high frequencies that you want left alone?
