Why the teleposts? Can't you use double TGI's to cover the span without the need for the bracing? I am not engineering the home and don't know the load bearing issues but there is always a material solution to these things. If it adds a bit more cost you can justify it by the lack of the intrusion into the listening space and the cost savings in not correcting for them.
Audio Room Size ???
My girlfriend and I are going to be building a new home. She has carte blanc to decorate as she wishes from the main floor up. I have carte blanc for the basement which is where I will build my audio/HT room. As for width of the room I have a choice of 12'6" and no teleposts in the room or 14'8" which will put two teleposts two feet into the room on one side. I would dress them up so they wouldn't resonate or reflect too much. As to length, I can go to a maximum of around 21 or 22 feet. My question is should I build narrow and keep the teleposts out of the room or wide and not worry too much about the teleposts? Would either of these width/length combinations give bad room ratios for sound? Thanks for any help.
