My basement home theater project (pics)

I will try to get that layout uploaded in the next couple of days. I've been so busy around here I just haven't made it a priority. However, I know it would be pretty helpful to you all as you try to figure out how the pictures fit together.

Wow, I have made significant progress since I started this post. The ceiling is nearly complete-I put a double layer of drywall down to help with sound transmission (5/8" over 1/2") and only have a few sheets left to do (I ran out of 5/8" this weekend and need to make a trip to HD). I realize that I am making a few compromises, but that's really what this entire hobby is about-weighing the various tradeoffs against one another and factoring in the cost. I'm sure that resilient channel would have helped greatly but the cost (for this project) just put it out of reach when I factored in the entire area that would have needed it. I also contemplated building a room within a room, but there are just too many limitations in my basement. It's something that I really struggled with and spent a great deal of time considering, but in the end it just seemed that this was the best way for me to go.

Since I am out of 5/8" inch drywall I got started on the walls. If you scroll back and look at the pic of the front portion of the room (you can see the screen mounted up high in one of the pics) you will see the two walls that are basically done. They are the front wall and the front right wall (the wall screen and the wall to the right of the screen). Next up is to start on the walls in the back (seating area) of the room. I will get some pics posted when I get the drawing uploaded so you can see where I'm at. Thanks to all for the input thus far!

formica: Lifting 5/8" drywall is not what I consider a good time! I am using a drywall lift to hold the drywall against the joists, but getting it onto the lift is the most difficult part. I brought 14 sheets of 5/8" home the other night and had my mom and wife help me carry it into the basement. I am impressed, to say the least!!! I researched it and found that a 1/2" sheet weighs in at 54 pounds. The 5/8" is considerably heavier! (We carried single sheets, btw).

Picky: LOL @ staying on my foreman's good side! My wife has taken to calling herself the "construction manager," and is quite on top of the project, I must say! lol It's great to have the girls down there (2/3 of them, anyway). When my middle daughter (Emma, 2 1/2), is down there with me and hears me grunt while lifting that 5/8" drywall, she always says, "ok daddy?" lolol Great stuff!

No, this is definitely not a weekend project!!! I always start with a rough idea in terms of cost and time and typically triple the time and double the cost. Those numbers come back surprisingly close to the real deal! (sad to say!!!)

InVeNtOR: Thanks for the tip about the quiet roc product. I had seen something about that (I think IndyKlipschfan used it in his theater) and it was one of those tradeoffs I mentioned in my last post. Make sure to start a thread with lots of pics when you start construction. I would love to see your room!

mas: I may take you up on your advice about the double-wall between the theater and my storage/furnace room. That is probably the only place that I had not thought about doing it, and probably one of the most important. I think what I will likely do is to get a single wall up (5/8") and see how much sound is coming into the room. If it is noisy enough, I could probably add a second wall just inside that room. Good idea, thank you.

The stairwell is to the far left of the front wall and will definitely be enclosed. However, I had not considered adding a pocket door there but that idea intrigues me as well. Do you know approximately how much width the pocket door adds to the typical 2x4 construction width?

Your ideas were very useful, mas. I have done a fair amount of research into soundproofing the theater but am substantially ignorant when it comes to room treatments. As you mentioned, that part is best left when actual measurements may be taken. I will keep this thread alive and perhaps learn something when I get to that part.

scooterdog: Thanks for the compliment! I know what you mean about always having something to do. This project has been put off for some time now due to those "other things to do!" I built the basement bathroom/laundry room that you see in one of the pics (Victoria is opening the door) and then gutted and refinished the upstairs bathroom as well.

Steve: My workaround for that pole is a bit of a question right now. I have considered boxing it in, but I just don't really care for that look. So we will probably either cover it with some sort of a nice wrap, or paint it black and leave it be. Some friends of ours have theirs wrapped in a nice oak style trim and another had his covered with a marble-looking adhesive. It will probably boil down to room colors, etc.

I recently stubled across a killer deal where I picked up the Infocus 7205 projector (1080i) and mount, a 92" Da-Lite powered/tensioned screen, 7 theater chairs (not quite what you are thinking), 4 bar stools, a really nice equipment rack, four movie poster snap-frames (with posters) and all of the cables (hdmi and component) for less than what I would have spent upgrading just the projector. Everything was approximately 1 year old and in brand-new condition. I was grinning like a mule eating briars when I happened across this deal!!!

I can't wait to see how this projector does in my theater. I have an Infocus X1 right now alont with a Da-Lite 80" screen and this 7205 is going to put my projector to shame. We had originally hoped to place a 120" screen in there, but it just won't work for a number of different reasons.

Trey: The only thing missing from that "projector mount" is an empty beer can!!! lololol But, hey, if it works, it works! And you don't see it when you're watching a movie, right??? Heck, my projector right now sits on a tripod when we watch movies and the screen is one of those portable jobbies that I can use for giving presentations at work.

I will post a few more pics once the dust settles...pun intended!

I was unable to locate my drawing of the layout of the theater, but these pics should make things fairly clear. The back wall is about 17' across and those side walls are about 11'. The distance from the front to back walls is about 24'. Comments are welcome!

***Edit-Just to clarify, the two smaller sheets of drywall that are located in front of the beam and centered by an electrical outlet are not yet cut. I have these attached by drywall screws but they are not yet glued as I will be placing the hushbox for the projector there and need to have access to what is behind those two panels.

We have a large sectional that will go in this back right corner. The back 8' of the theater will be on a 6.75" riser.

LOL, nope, haven't been on the treadmill in quite some time, actually! My wife had to buy some silicone spray for the track due to the dust residue! I think you can safely say that I'm getting a pretty good workout about every night down there, although not much cardio. Lifting that 5/8" drywall is not something that I would look forward to when I got home from work!!!

Thanks!

alright, i hope i didn't bust you out too much, it just made me laugh. to tell a quick story, my boss at work e-mailed me a pic of him at the Renaissance fair with this "hot half naked chick." i showed the wife, and she starting laughing at it. being a guy i couldn't see what was funny about a hot half naked chick. she pointed to the right of her and there was a mother pushing her sons in a stroller. once son had is view blocked by his hand, and the other was dead locked on her open bare A**! it was so funny i printed it out showed it to my boss, and then showed him the mother's sons. to my disbelief he had never noticed the wife or kids! to make the story even funnier, his wife hadn't noticed either! it makes you think what she was looking at!

take care! i hope the story made you laugh! keep the pics comming!

another quick story about things in pics....my wife let me take a photo (not a porno type) of her in her shirt, bra, and panties. let me say again, nothing dirty, just cute. well the she said i could put it on my tool box so i would remember her while at work. i did tell her a thousand or so guys would also see it, she still didn't mind. one such guy was looking and he starting laughing. he pointed to an object in the background against the wall. it was a long box and it read "World's strongest bed frame." Innocent enough, we had just bought a new frame from the store we got out mattress, and that was the brand they carried with it's logo/selling point. it got a good laugh at work, not to mention the high fives from the guys saying stuff i won't put on the forum.

Update: Riser is complete and first two coats of mud are on most of the seams (butt joints withstanding). The riser is 8' deep, the entire width of the theater (17') and constructed with 2x6s (1 foot on center) and 1/2" osb). I'll try to get a few more pics uploaded in the next couple of days. Thanks for the comments.

Wow, making lots of progress. Are you doing all of this alone?

Real quick, does your riser resonate at all when you tap your foot on it? Usually you offset the studs a bit and put little crossbraces going perpendicular to create spaces of different lengths that way they resonate at different frequencies. If you're really hardcore, you'll fill it all with sand or some kind of insulation to absorb any possible resonances.

It's not a huge deal and if you don't notice anything now then don't worry about it too much. If you notice just a little bit, then it's quite possible that a thick carpet pad will be able to dampen it too instead of ripping everything apart.

Btw, had I known you were going to do a rear riser, I would have suggested last weekend at Glenn's that you should consider the option of integrating helmholtz resonators into the floor. If you can hold off on finishing the riser for a bit this is something that can be measured and implemented later on. Let me know if you're interested and I can get you some more info on it.

Thanks, jacksonbart! Yeah, I am starting to get pretty excited as we're nearing the home stretch, but also keeping in mind that the homestretch is one of the most difficult because of the temptation to cut corners on quality in order to finish faster. I'll keep posting pics to let you guys see every stage...

Who-unfortunately, yes, I am doing all of this alone. It's been a long project. I started the basement by gutting an old bedroom that was 11x13 and building it out to 13x18. That room is nearly complete-it's been primered and just needs a few small tweaks and it's ready for paint. Then put some trim pieces on, closet doors and so forth and I'm home free in there. We're homeschooling our children, so I'm sure the room will be used for that occassionally.

I was concerned about the resonance of the riser, which I would have described beforehand as an echo (is that the same thing you're talking about?) which is partly why I elected to have a spacing of 12 inchest between joists, rather than sixteen inches. I figured that by overbuilding it a tad I would have less "echo" or resonance in there. I'll do some testing on it tonight by tapping my foot but I can tell you that I haven't noticed much noise while walking around on it. The riser was constructed by gluing and screwing the osb to the 2x6s. I suppose it could be removed, but it would be an absolute pain methinks.

I haven't followed the thread on helmholtz resonators-how would they help me in my room? I saw pics of yours from your thread and understand them to be cylindrical but beyond that don't know too much. How would they be incorporated into the riser?

Thanks, Who, I appreciate the feedback.
