ETA: Name changed to reflect the unique nature of my space. It is in fact a wide hallway since you must travel through the room to access the rest of the basement.
So it looks like it's my turn finally. I helped my friend with some parts of his theater room in 2003-2005 and knew that some day I really wanted my own space. This won't be perfect or ideal, but I hope it will be the best than can be done with the space that I have in my house.
Challenge- build out a fully finished, acoustically treated, and decorated movie / 2 channel room for $5000. And I am paying for some of my labor, but doing a lot myself. Room is approx 12 x 18' with an intruding HVAC, sump pump, and furnace.
Pictures are useful, so here's what I'm working with. I may be missing something but I hope not.
You'll notice that the orientation seems to be off by 90 degrees. This is intentional. The problem is the layout of my basement. Not only is this room between the stairs and the rest of the basement, but the laundry room is also down here. So, in order to facilitate ease of passage, this compromise must be made. One advantage is that we should have nice spacing for most of the speakers except SBL and SBR.
Electrical. I still need to figure out the best place for the outlets and lights. Code states 1 outlet maximum 6' from every door. And then 12' maximum to the next outlet. It appears that this means you need one outlet on each side of the door within 6'. So in my case that will dictate at least 4 outlets. Preliminary electrical:
I am going to try and squeeze 2 layers of 1/2" drywall and 2 cases of green glue into the budget, as well as some GG sealant. Also resilient channel. The green glue and DD will be used on 2 walls and on the ceiling. The two walls that are exterior walls will be a single layer of drywall.
It's called the Over Budget theater because my wife said "I'm sure you are going to go over budget" and I'm pretty sure she's right. I will be posting all the costs for anyone who is interested. We'll see how close my estimate is. My current budget says $4990.13.
As far as equipment goes, for now it will be what I already have- Paradigm Monitor 9s and CC-290 for the front stage, my 18" and 12" subwoofers- for now. I am hoping to build a SEOS kit from DIY sound group for the SL and SR channels, we'll see how that goes. Oh yeah, TV. We have a 46" Toshiba Edge-lit LED TV for now. I am trying to convince my wife we need a 60" or 70" TV- at that viewing distance, should be plenty big enough. I am kicking around the idea of running some HDMI cable in a conduit in case we get a projector. Although screen size probably couldn't be bigger than about 80"
I expect I will have a TON of questions and so I am going to say thanks in advance for your advice and tips.
