Rather new member here although I have been around (reading) for many years. We recently bought a semidetached house in the rainy Bergen (Norway) where we'll live for the time being. After the civil war, wife and I agreed on a peace treaty: finished attic for her atelier/hobby room and basement-to-be-finished for my listening room/man's cave.
After some consideration I have decided to make my life a bit more complicated and use the room also as a family's movie room.
Following some struggle to meet the code when it comes to thermal/humidity insulation, I am now planning on speaker placement/wiring/ soundproofing/acoustic treatment. I have to say that my focus is to get a good sounding room rather that a sound-proof bunker but all the reasonably costed (in time and money) acoustic insulation measurements will be considered
I believed I have everything I need when it comes to sound: 2x Infinity Beta 50 towers, 2x Infinity Beta 40 towers, 2x Infinity Beta 10 bookshelf, 1 x Infinity CS360 Central, 2x B&W ASW650 subs, Denon 2312 7.2 receiver, etc....a bit old but I am very please with the overall performance.
I would say that stereo and MC music are my priorities but that's maybe because I never owned a projector
The room is somehow challenging: is a 9'10'' x 14'11'' rectangle. Wall's description is as follows:
9'10'' wall with an exterior door (to the garden) and a high window (around 6' from the floor). Thick wall made of Solid concrete+concrete bricks
14'11'' wall facing the neighbor's basement. Thick wall made of Solid concrete+concrete bricks. Stus are decoupled from the concrete.
9'10'' stud wall with a door to access a cawl-ish space where I'll have a small workshop and bike storage (4 to date, more coming
) plus a lower area where I store wood for the fireplace and miscellaneous stuff.
14'11'' stud wall with a door to the washing room, the staircase and a door to a walking closet under the stairs.
10cm(~4'') of fiberglass blankets will take care of the insulation. Following the code, the exterior wall has an additional 3'' layer or XPS. Single or double drywall can be hanged but I don't want to subtract more space than necessary
Ceiling is rather low, around 7' after the soundproof hangers and the drywall. There are 4'' of fiberglass between the joists. Ceiling is already painted but I would consider an extra DW layer is that is gonna make a huge difference - kitchen, main entrance hall and small toilet right above
Floor heating and parquet is already in place.
I would appreciate advise on:
1. Is there room to 7.2 sound (with backs) or I should be happy with 5.2? Maybe front heights?
2. After a lot of thinking I came up with the arrangement you can see in the attached image. Considering the viewing distance, will you use a
projector or a 65'' OLED?
3. Related to 2, would you change the orientation and place the sofa over the large axis to gain viewing distance even though you will
sacrificed a more ideal speaker placement?
4. Are points 2&3 all bollocks and I should for a projector no matter what and then do my best with the speakers? Please, convince me
5. Should I wire the ceiling for a future .2 or .4 Atmos upgrade or it is just not worthy in this room, specially considering I would need a new
I can go like this forever so the next question summarizes all the previous ones, What would you do if this was you basement?
Now some pics of the current state and the 2d and 3D models with my not-written-in-stone arrangement. I can post some pictures of how I have been doing the stuff if someone thinks that is relevant.
