Hello all,
I hope those answering will consider the dimensions of the room (provided below) as they pertain to nodes, nulls, standing waves SBIR and anything else that might factor in. Also, please know that my plan is to properly treat the room no matter which floor plan is chosen.
I have mains, and a sub and am open to adding a second sub later, if beneficial. It is not a HT room.
In case anyone finds it useful, the room is upstairs on a suspended floor. The floor joists are covered with 1 x8 boards edge-to-edge which forms the first subfloor. On top of the first subfloor is particle board that will be removed and replaced by 3/4” plywood. The PB is not a suitable subfloor for the engineered wood floors we’re going to install. (Opportunity to put acoustic material between boards and plywood)?
The wall in question is a closet wall that spans the entire width of the room and currently serves as the rear wall of the room (behind my head)
Question: Do I leave the wall or do I remove the closet wall which will create a new room with a significantly larger volume and length? I do believe the added volume and length are acoustically beneficial (I removed the doors long ago) but wonder how much access to the additional space is needed to fully harness the acoustic advantages. As an in-between measure, I could leave the wall but increase the size of the opening if someone were to suggest unique benefits from doing so.
Is it a no-brainer (as if such exists in acoustics? Lol) to remove the closet wall and fill the area with lots of LF absorption and diffusion as needed?
Relevant consideration: Based on listening tests, the closet doors were removed which leaves a 48”W x 80”H opening between my room and the closet volume. FWIW, the closet doors are not centered on the back wall and even if the wall stays, the opening will be reframed to the center of the room—which will center the opening behind my head. I wish my room were wider, but I do appreciate that its length allows me to have the speakers way into the room and still have my head far from the rear wall. I’m utilizing the longer length to some degree now with the closet doors absent.
The closet is large. It adds about 20% to my room’s volume and 63” to its length. The existing room is 122.5” wide sheetrock to sheetrock, 106.5” High (1.5” short of 9’) and 224” (18’8”) long from front wall to the rear wall (closet wall). Room length with the closet doors open is 287”. Just shy of 24’. The room is very symmetrical, but not utterly. Luckily, the relatively minor asymmetries are all in the last 37” of the rear of the room. I can describe the asymmetries if anyone requests. The space inside the closet is far less symmetrical, however. There are sheetrock chases which house HVAC ducting to the first floor and a slanted roof line, but the depth and volume is what I reported, net of those irregularities.
The rear wall of the closet is vertical to about 5’ or 5.5’ at which point it hits the roof-line (joists). If my closet wall is removed, the rear wall of the closet will become the rear wall of my music room. It already is, to the extent that there is a 48 x 80 opening in the closet wall currently. BTW, two large foam sheets are leaned up against the back wall now. Each about 2.5-3” thick, they are old mattress toppers which cover a very large surface area. The foam is not ideal, but much better than nothing absorbing back there, i think.
I may do another thread to cover a few other room remodel questions, after the wall question is settled.
Thank you so much,
Rick
