Cleaning up again, almost done! Just some painting to the soffit where the projector hangs and some touch-up left. Well, inside the room anyway...Link to front wall constructionRiser construction (allegedly a semi-hermoltz bass trap as well)SoffitSide WallsBack WallWith Chairs
Will do the same for the rest as I go
Hello all, I'll try to keep this as short as possible to sum up where I lost my way and kindly ask for some advice or ideas. I have a small room, about 16x12.7 in an already finished basement. It's in the corner so three sides brick walls but they are insulated and drywalled. Still the echo/slap in there is pretty bad. Anyway, my initial plan was for a soffit and hopefully to get Jeff out there to paint a night sky mural and have the black fluorescent lights glowing the mural. My room already had one soffit in the back wall hiding the ductwork but it was lower than I wanted it all the way around so I framed the soffit a little higher, about 10 inches. It's pretty much done, have the lights in there, insullation, wired up my speakers but I can't put the last couple of pieces of birch on there to seal it up until I figure out where I'm going with the sub woofer. That in turn led me to the many questions around bass traps and sound absorption for all walls for that matter, led me to avs forums, the bacon race and tons of great ideas and now I'm taking a step back
I love the room that damelon and BIG did, the Bacon Race Theater and it's already similar to what I had in mind. Originally I planned on doing some wainscoting on the walls with a couple of small columns and panels between the columns above the chair rail up to the trim in the soffit. However, with the sound as poor as it is down there combined with as much as I hate staining and as good as those floor to ceiling panels look, I'm thinking of doing something more like that instead both for look and function.
I know Damelon had the work of an acoustics expert in the design of his walls but do you think that the same principal would work for this room? From the Bacon Race, side walls are 1" 3lb dense cotton, front wall 2" 3lb dense cotton, back wall 4" OC703. Actually the back wall I believe had 2 inches of air spaced with 2 inches of OC703. Looks like he went floor to ceiling and I don't hear him complaining about adverse affects. I can look at this mirror thing and reflection points all day and I can pretty much tell you my HT will be in the same state it is next year b/c the more I read the more confused I get.
Also, if you look at the pic of the blue tape screen, that will be a 120 inch Dragonfly screen which nearly takes up the whole wall which I kind of like. Leaves just enough room to either leave the towers there or build some columns on the side to hide them. Since I have a 12 inch riser in the back, I likely need to bring those towers up. As much as I'd like to build the stage, not sure if it's necessary, perhaps I'll just build stands and extend them up as columns for those towers and keep them under fabric similar to BIG's towers and maybe stack the top of them with foam for bass traps? Does that even make sense to have all of that going on in one column? Is it necessary to put insulation on the entire front wall and then build a false wall in front of that for the screen and everything else or am I good just mounting the screen on the wall and maybe going 2 inches deep around it with insulation and possibly those 2 columns? Just tried to do something in sketchup for the first time but it will be a heck of lot quicker for me to just draw and scan it when I get a chance.
My riser is almost the width of the room and about 5 feet deep. The front row will be pretty close about 10 feet from the screen which I'm told should still be ok. I posted the question about turning this into a bass trap but I think I decided against that. Seems the best for me and to be sure it doesn't mess anything up is to insulate it and have a few layers of plywood on top with green glue like they say and I think I'll be good with the riser.
The carpet in there now is getting ripped out, new carpet will go over the floor and riser. I had a plan I was following but with all the great HTs I'm seeing here I pretty much tossed that out. Serenity now. Actually, this is fantastic. Lots of fun and glad someone sent me over to this site.
So i tried to keep it short, that was kind of long. I guess my questions are, any advice for the walls? I'm bailing on the broadband bass trap riser so it sounds like I should just fill it with mineral fiber, where the heck do I get that? HD and Lowes here only have the pink stuff and if that's ok does it have to be unfaced and a certain R value? Otherwise, where do I get the mineral fiber and cotton insulation, I'm sure I can find that somewhere in the Atlanta area right?
Here is the front wall, hope that screen isn't to big.
Here is the soffit, as soon as I figure out the rest I'll finish all sides, sand and poly and crown. Black lights will be behind the crown.
Side view, there's the riser which needs to be stuffed and topped and man the room looks even smaller in pictures. I don't think there is any room for columns on the side walls, maybe just columns in corners for speakers and bass traps?
Thanks in advance!
