"Even the companies who create acoustic pannels work by absorbing frequencies. This means less information."
Actually that’s not really true, well, it could be true if one was all thumbs and put the panels in the wrong place, but ordinarily the panels absorb *unwanted* sound, e.g., echoes or first or second reflections or standing waves. Acoustic effects that interfere with the primary signal. That means more information, not less information. Comb filter effects are not a good thing under any circumstances. Same goes for resonators like those cute tiny bowl acoustic resonators. They could hurt the sound if put in the wrong place but when used as directed there is more information, not less.
