Hi all. I have been lurking on here for awhile trying to learn as much as I can. I am not building a totally dedicated theater room, but the basement will have a theater / wet bar / pool table game area as well.
I have just finished framing the entire basement and am now beginning to run electrical. I am currently agonizing over how to build my riser. Mainly the height and to let it float or build it in. There is too much to read and too many differing opinions, so I would like to start there.
Here is a rough drawing of the whole space. You can see the pool table and the wet bar to the right. You can see the theater room to the left. There is no wall there - there will be just 1 pillar and I have the dimensions from the 2 walls to the pillar. They are both about 94".
Here is an up close image of the room. You can see my ceiling height is going to be 93 1/8". I currently will be hanging a 63" Plasma that I have only had for about 1 year. I will be wiring for a future projector if I choose to go that way. I put little squares to symbolize my 2 fronts and center channel around the TV. I also have a little area cut out for my components down in the corner. I expect to put my sub up here as well. I am thinking of making a 7' x 10.5' riser. That will keep is just within the back section behind the pillar. I am planning on 2 rows of theater seats that recline. They are Southern Motion and the 3 together create a row that is 110Wx38D. They are 68 deep reclined. The backs are 41" high and my head sits at about 46" high when I sit fully straight up in the chair. Lastly with where the chairs are going, I am going to have to put the rear speakers in the wall and not above due to some pipes that take up the last rafter. Also, I am thinking the bottom lip of the TV will be at 51". The plan is also to do theater curtains we can pull closed between the pillars to close it off when we want.
So a few things I currently am trying to figure out.
1. How tall should I make my riser. I used the calculator and the minimum said 4.5 inches. I know a step is 7 3/4. I would like to keep this to code, so if I do a 7 3/4 riser will I regret it. Should I just make it taller like 10"? If so and I do a step - do I just need to make one step or would it need to be all around the riser? What do you think the tallest would be with my ceiling height?
2. Should I build the riser into the wall? I am thinking it will be cheaper and easier to just build it in now rather then just carpet the whole floor and then have the carpet layers carpet the riser. Then I can plan my electrical around it being a permanent fixture.
3. I need to factor in if I do a bigger screen in the future - TV or Projector - I really do not know how far back I should wire the projector. I have a 30 ft HDMI cable on order. My plan is to put it and an outlet somewhere in the ceiling.
4. Does anyone see any problems with anything I am doing, or anything I am not thinking about?
I appreciate any feedback.
