Some updates, working on the column fronts and still deciding how to create the fabric panels. I am thinking I may add 2x2 strips to overhang from the backside of the cutouts and use either magnets or speaker grill guides to attach the panels. I will be ordering GOM FR701 for the panels but I am a bit concerned about sagging with the size of the front columns, the surround columns should be skinny enough not to sag. Also I was toying with the idea of raising up my towers in the columns to allow for Subs up front but I am thinking against this as it will as it is likely not the best acoustic approach. I am opting for running subwoofer cables to the two back corners of the room and leave the subs out of any secondary enclosure.
I have a family friend coming out to do all the trim work and surround columns (i will be cutting the front panels with the speaker cutouts and backing) in late September so will need to finish up the Front stage and start wrapping in 1x (trying to clean up the lines before trim). Very happy as this will greatly speed up the build. I will be running wainscoting with 1x and picture boxes. I will also be adding crown at both levels as the back half of the theater ceiling drops down about 8". I am having him drop the crown in the front part of the ceiling so i can run LED strip lighting. Once trim is in I will be painting all the trim, screen wall, and ceiling in flat black. The walls will likely be gray. Carpet is already sized and picked out, going with a grey twist that has a lot of white black and sliver tones, its a bit brighter to provide some good contrast with the blackness of the trim and walls. i will post a pic of my colors and carpet soon.
