Patrick,

I was thinking the same thing about the soffits. It appears as though you are making the soffits out of MDF. Wouldn't it be a good idea to use some fabric covered rigid fiberglass? Or even a batted fiberglass with some sort of fabric grill?

Yes, it is MDF and it will be covered in fabric. Notice the rear cutout, that is where the projector is going to live. The projector will be completely closed in with glass window to project through.

Also, be sure to isolate your ceiling, or take some sort of sound block measures before you drywall.

We both have young children, and that is one thing I really wish I did when I finished my basement (at the time I wasn't into HT). You want to be able to have a good listening volume in the evenings while they are asleep, but without everyone in the house being bothered by it.

Basement Bob will know how to do this effectively better than I. He pops up in every thread I have seen on the subject.;)

Dave,

Drywall is finished, doubled up on ceiling and walls in HT. I didn't do any decoupling from the ceiling above, only R-30 insulation. I am not too worried about kids rooms hearing noise, maybe some bass rumbling, but not too concerned.

Thanks,
PW

This sort of thing was why I asked (that and corner traping): http://www.asc-home-theater.com/products-soffit2.htm

I didn't see anything actually inside your soffits, so I was curious if you were doing this sort of absorbtion.

Bob,

Thanks for that link, interesting product. From the earlier pics, you can see that I had a framed bulkhead with drywall to cover a large drain pipe and a gas line. For cosmetic and functional reasons, I built the mating soffits to match.

Speaking of "Stage", I hope to get that done by this weekend!

Good luck on your project Mike.

Stage work has begun. I didn't get too much done over the weekend, it was just too nice outside (mid 70's in Indy), so we did yard work and the zoo instead. I have found that work week nights are the best time for me, once my daughter is put to bed.

The curve of the stage seems to be working out, except I cracked one 2x8 in a spot where I cut the slits. To cut the slits, I just put the 2x8 up on my sliding compound miter, adjust the blade height so that it leaves about 3/8" uncut and make slits every 3-4 inches.

Also, you can see that I started planning out the angles of the front stage wall which hides the speakers...

Patrick,

I'm in the same boat....with the kiddo that is. He is down at 8pm and I am usually down in the basement---sorry HT by 9pm. I have been worn out because I get hooked and don't come back up until after midnight. I sometimes wonder who that strange person is lying in bed besides me at night and then I am reminded by the wedding photo---oh yeah...that's my wife:) I'm sure it will all be worth it in the end.

I am still in early framing stage right now, and will try to get some pics up soon. Your HT looks great.

The good thing is the soundproofing is passing the test so far, been running the saws and banging down there and she hasn't awoke yet because of it.

Classic story...

My daughter is about 17 months old and she is putting words together to form sentences. Well, we have been moving a lot of her toys down in the main basement the past week and put up a shelf for her toys. It seems there is something new or moved down there everytime she comes down there and she always says, "WOWWWW, Thank you mommy daddy..." Well the other night I was bringing some 2x4's down and left 2 boards by the bottom of the stairs. My wife called me today laughing and said Audrey said, "wow, thank you mommy" when she saw the lumber laying there!!!!

Stage construction pictures have been added....
post #43 of 166
Looking great! Thanks for the detail construction pics on the stage. I see you put kerfs in the curved section of pressure treated wood. Did you have any issues with attaching it and getting it to hold? I've got to add a second tier to my stage based on a design change I made (I started the project 3yrs ago and then our second was born). The existing stage was meant to be a game table area (pic attached). But luckily technology changed and I got an IF7200 instead of a RP Mits 55". Good things come to those who wait! Good luck on the rest of the project!

Vshine, thanks. Yeah, I made cuts into the board about every 3 inches or so. It was easy with my sliding compound miter saw, it has an adjustment to set the depth of cut. I laid a piece of 2x2 scrap on the saw, then put the 2x8 board against that so the cut would be even through the 2x8. I had to scrap one 2x8 board because I bent it too much and it cracked in one of the slits. I fiddled with the curve and made a couple adjustments to the "curve joists" as I went along. I was pretty happy with the overall shape. I need to round over the top and bottom and then attach it to the frame.

Oh, and next time, I would cut the 3 layers of plywood to size, bring them downstairs, and then assemble them. Carrying a 2" thick piece of plywood that is 30"x99" from the garage to basement is a bear. My wife was a trooper and helped out, good thing she works out!

Patrick,

Are you going to attach your stage in any way to the wall? Mine will be from wall to wall (you can get an idea from my plan layout in my link), and I am afraid if I don't attach it, it will rattle/rub against the walls. Thoughts?

My stage will be spaced out from the wall by about 1/2". I will only have the stage in the middle of the wall. My L and R speakers will not be placed on the stage as they are not floorstanders.

Well, progress was stalled a bit with the nice weather. I still had some cosmetic work to do on our deck that I built last summer, so that took precedence.

Here is the latest Webb HT Gallery. I actually have more pics that I will upload tomorrow.

My front stage area and soffits are almost completely framed out and I also have pictures of the projector mount and screen placement.

Of course, I wanted to be done by now, but I am not rushing this!

Here are some pics for you so you don't have to go to the Gallery...

I started on the screen wall framing, but ran out of 2X4's, my goal is to get all the framing and cutting done by next week, so I can get the carpet guys back in.

Looking good.

Sorry if these questions were already answered, but:

Where are your subs going to go? Off the stage?

I couldn't see any images that showed you filling the stage. Did you fill with sand, etc.?

Is the stage going to sit on decoupling feet?

Thanks in advance.

Patrick,

That's one heck of a riser. Nice decking!

Cheers!

Thanks, I couldn't have done it without my neighbor's help. Once the layers were sandwiched and screwed together, we removed it from riser frame and flipped it to router the 'round over' sides, then flipped it back on top of the frame to finish routing the top portion. I was really happy how it turned out and especially pleased with the step.

jf1, the stage was not filled with sand, only insulation. The sub (1 right now, possibly 2 in future), will sit on the floor off to the sides of the stage. The center channel is getting placed on a wall mount above the screen. And the Mains will be mounted on shelves on the angled portion of the proscenium wall.

Thanks

Thanks for the feedback.

Hope you can bear with me, but:

Is sand now not "in vogue?" I hope so, because I was dreading the thought of hauling a sandbox full down to the basement. Is the feeling that with the subs far enough away from the stage, the stage will not vibrate, or is insulation enough?

Do the mains get "backfilled" with insulation or any acoustical treatment?

Thanks again.

Some very nice work! Love the built in hush box/soffit. Great idea.

No, that is cool as well but in a differnet way. His is fully in his soffit so when the cover is on you just see one big soffit. I have been thinking of hushbox designs and I have a return a few feet on the wall above my projector. A neighbor thought it could be incorporated to look like an "old time" theater where the projector is in that little room up behind you.
post #59 of 166
Just having fun, Scott.

I know what you were getting at - my situation called for pretty narrow sofits, so the incorporated hush box had to be larger - probably should have been wider still, but I pull a hell of a lot of air past the projector.

If I had my druthers, I'd have the projector in it's own "Booth" with a glass divider.

Wow, what a difference carpet makes! I now feel like I have actually accomplished something. After the installer grumbled about how much work this would be, he got to it and did a great job. He was there by himself from 8 am until 5 pm.
