So before I start down the path of treatment I need to decide on a listening position. The room is 15 x 12.3 x 8 and is used for music mixing and hardware synthesizer production recording. I have to consider equipment placement. I am going with the monitors to be pushed up to the front wall as possible. I am not concerned at all about soundproofing or noise. However this is the issue.

The left front corner has a cheap hollow door that does not allow permanent treament and I would need to have some on rollers to roll in place when mixing. A PITA but I could do it if needed. There is also a 2 x 9 x 8 closet with louvered bifold doors in the left rear corner of the room. I could located the listening position on the rear wall but it would put this closet exactly inline with my right ear and the right speaker first reflection. So the questions are these:

1. Which is the lesser of two evils as far as listening position considering there will be treatment (either permanent or mobile)?

2. In either case what should be done with the closet? Im assuming to replace the louvered bifold door with solid sliding doors. I could put some absorbtion in thr deep pockets of the closet but I need the center opening(width of doors) for storage if possible.

3. Considering Im not trying to soundproof anything would there be any benefit to changing the hollow entry door to a solid core? Does this depend on if the listening position stays located near it?

I must commit to a listening position and equipment ergonomics si I cant move forward with treatment consultation..

Thanks

This is an example of using tactics without a strategy. You must first look at the modal pressure issues within the room. Set up is not a priority at this stage since it will change after treatment for modal pressure issues. Once you have identified the frequency, amplitude, amd location of the unwanted modes you must then assign the proper treatment. Most frequency issues below 100 hz. take 12″ of space to treat properly. The closet may be able to be used to absorb modal frequencies at that room location.

I guess my concern is with symmetry with treatment. Does the material composite of the door( solid vs Hollow), effect the symmetry in that location of how treatment is interacting with the low freq modes? Is there any fruit in a solid core door outside of soundproofing?

Will your foam panesl in front of a lovered door vs a solid door, have the same level of effectiveness on high frequency reflections above the shroder freq?

And with treatment in that closet for what ever modes are in the closet itself or that side of the room, wouldnt there still be left/right symmetry issue in the low end at that location of the room ?

Your concerns about symmetry must take a back seat to low frequency management technology which takes at a minimum 12″ to treat. Once the room is managed correctly with low frequency treatment, you then move to middle and high frequency reflections.
