I'm building a dedicated listening room 21' x 12.5' x 7.5' (L x W x H). I know this is not ideal, but it's a basement room limited in height and width. The basic construction is nearly done, a double studded wood frame with R13 insulation and a double layer of drywall with "green glue" between. Also, the drywall is separated using furring channels and special brackets to isolate it from the ceiling. By the way, there are no windows or glass of any kind in the room. Just drywall and eventually a hardwood floor with a thick area rug in the center (currently OSB subflooring on top of concrete slab).
My question is, how would I best treat the room acoustically to effectively reduce room reflections and handle bass energy? As it is, if I clap my hands while standing anywhere from the center of the room to the front corners, I hear an increasing reflection in the room. As much detail as possible would be great...
R, You could have built the low frequency management into your walls. Unfortunately, the tactic of drywall and green glue is only performing above 125 Hz. What is the diameter and number of the low frequency drivers in your room ? What is the average listening pressure level in your room ?
R, Low frequency absorbers that work well are too heavy for wall mounting. Our ACDA -10 carbon units weigh 250 lbs.
Also, should I use bass traps in the corners if I employ these panels? And Where in the room should I place these ACDA panels?
