Equalization changes the speakers input into the listening space; room treatments change the output of the room to the listeners ears. They are both useful but totally different tools. Every time you move a speaker, schangecthe toe-in, raise them up or down, you are changing their input into the room. It is every bit as much equalization as turning a knob, with the added complexity of changing the speakers acoustical interaction interactions with the space. Equalization cannot fix a bad room, ever. That requires acoustical treatment.
Sound meter + equalizer = problem solved?
I think it’s true. Digital room correction is even better. Are we just spinning our wheels and wasting time trying to solve the room acoustics/Fletcher Munson problem otherwise? Could audiophile dogma ie “don’t mess with the signal, dummy” just be completely wrong in practice? What were we thinking?
