All, I just finished reading chapter 8 in Dr Floyd E Toole's Sound Reproduction 3rd edition where it discusses room nodes, sub positioning, solutions (bass traps). When I rebuilt my theatre 3 years ago, I stayed with the four identical subs (SVS Ultra passive cylinder) in each of the four corners to achieve high Mean Output Level (MOL) and good Mean Spatial Variance (MSV). I didn't want to build bass traps at that time because of preconceived notion of space issues (lack thereof) as I planned on using large deep floor standers for LCR. I have changed my mind now that I read chapter 8 and knowing I have the space now (JBL 708Ps replacing Polk LSIM 705 floor standers)
My questions are:
1. I plan to build four floor to ceiling bass traps as per the diagram below indicated by the red triangles. If I want the subs in the "corners", it will be approximately be 1.5" from the corner vs being flush pre corner bass traps. Will having the subs out from the corners 1.5' still provide the high MOL and good MSV? Are there gotcha's I should be aware of?
2. How effective will adding partial eg not floor to ceiling bass traps indicated by the gold triangles on the short 16" walls adjacent to the screen be? These bass traps will need to be about 3.5-4' tall with the midpoint mounted midway on the wall as I have a return air vent facing the seating area on the bottom of the wall and wall sconce near the ceiling. The "wall" is really only a 3/4" sheet of ply on the theatre side
