I have a question regarding HVAC. My HVAC is very close to the theater 5 feet from the back wall. The ducts run between ceiling joists. which option would likely be more quiet? I have long ducts about 16 feet with wo air vents per duct.
1. Normal metal ducts with silencers and insulation around them.
2. flexible ducts
The ducts are isolated from other ducts, and have three 90 degree bends. So, I think fan noise may be more of a concern than voice...
