assume you (at least) will reply!!
Once I finish my speakers, I will be able to get around to room treatment, and prob the easiest to do in the corners are super chunks type absorbers.
BUT, my ceiling height is about 17 feet. BTW, tri corners are out for treatment (tho I mainly mean the ceiling, could imagine getting away with the floor).
OK, 17 foot ceilings (5.4 metres), no doubt it would be best to do the full height but am a bit reluctant for mainly aesthetic reasons.
What would be a good compromise for the height?
(and just to stir the possum for funs sake, I also use digital eq for room correction. Having said that, I feel the best solution is both rather than one or the other)
Basically no other treatment, except for rugs on the wall to stop the echo that you get in a big solid room (about 9m by 5m, with a very deep and wide bay window, about 2.4m deep). My main concern would be bass traps, and then investigate diffusion behind me. I think I can get away without first reflection treatment, mainly as there is at least 1.5 m between the walls and speakers, and also I sit diagonally to the corner so the room 'falls away behind me'.
