I was wondering if you guys could give me a piece of advice on treating a protruding (positive if you will) corner of a fireplace that is close to the first reflection of my left channel...
I have GIK Tri-Traps floor to ceiling in both front corners now (as well as a few other positive changes to the room that are of no concern at the moment), and am ready for round two of treatments before my new speakers arrive... A large portion of the fireplace hearth wall will be treated.... With new speakers, will come new speaker placement, the system will be split and moved to two racks on either side of the TV... I have done some measuring and think I am going to need to treat the corner of the fireplace closest to the left front speaker.
The fireplace is represented by the black rectangle on the left side wall... It sticks out 8" into the room.


I have though of just a regular 242 panel custom fit, or an art panel with matching brick pattern OR... ???
Will I need to treat both edges of the corner or could I get away with just doing the outward facing (front) edge of the fireplace?
Any new ideas or approach I should consider here???
Thanks so much
Jason
