HT Part Deux with Coffered Ceiling

I think the seven-year itch finally kicked in. Here is what my theater looked like six weeks ago.



I saw some good postings, and couldn't stay away from some ideas I noticed, especially the acoustics panels in YzfBossman's theater. I just got to have it.

I have spent about six weeks of "weeknights and weekends", and this is the current status.

Front view:



Rear view:



I've been busy working my butt off, and not have time to post, but I'm taking pictures as I progress, and I will be taking few breaks to post the column and ceiling details next week, and the updates going forward.
Thanks to other members who has posted in the past, (this is my second rodeo), and believe me, I'm always learning something new every time I login.

Major construction is halfway, next is the moldings..... And yes, there will be lots of them, especially in the ceiling, and around the columns.

Back On

I had to hold off on the theater build to build a side project, compliments of my Home Owners Association. I need to add a cover for my trash bins on the side of the house.

Column details:

I got most of the ideas from the forum, and i tweaked a little to match what I'm looking for. I will eventually wrap the opening with a panel molding and build a panel cover with speaker cloth material.

Test with Klipsch RS-52ii surround speaker.


Six of Eight completed.

Coffered Ceiling:

The design was based on 6x3 = 18 boxes.
Construction material was mostly 3/4" plywood.
Started with the long span across the room, and built the cross pieces, and attach with screws, one box at a time.



Span #1 completed, a couple of cross pieces attached.


These clamps were very helpful in holding things down before applying screws.


Row by row, Cross piece by cross piece:


Completed, 1/2 inch bottom piece added, and I ran the electrical wires for the 4-inch can lights.

Misc

The trusted Kreg jig was very instrumental in the assembly process.



My kitchen island becomes an extension of my garage. Makes the perfect assembly table.



My cars are very jealous of my tools right now. They've been temporarily kicked out of the garage.

Paint before Moldings

I decided to paint the moldings before install, while they are drying, we decided to start painting the room, and the coffers are going to get a red base that will match the acoustic fabric panel on the walls.

Ceiling Speaker help

The coffered ceiling has about 6-inches plywood-made beams.
I just purchased two in-ceiling speakers, and i would like to know what your recommendation is between these two options.

Option 1:
Build a 6-inch plywood box that matches the existing coffer beams and install the speaker inside the box.

Option 2:
Install the speaker in the drywall inside the coffer. I'm just worried about heat in the attic. It's about 120 degrees up there around July/August.

Thanks

I would think install in ceiling with backer boxes in attic. Here in Phoenix , our attics get a lot hotter than that and my speakers are fine. Just a thought.
P.S. Room looks great!

Wow awesome. How deep are the beams in the coffered ceiling? And how high is the ceiling. The moulding looks great. I've got 8' ceilings and want to add something like this to the ceiling but I don't want it to come down too far if you know what I mean.

The beams are 7-1/2 inches. My ceiling is 9ft tall.

I will add my own "Wow!" to the accolades. A total piece count would be mind boggling. Great work.

Dolby Atmos and DTS:X Retrofit

Moldings are finally completed!!!

I installed four brackets for four indoor/outdoor speakers in the ceiling, and the accompanying wires this week. I chose outdoor speakers because I have no attic access, and plus the fact that it could be 120 degrees in the attic during the summer here in Texas, therefore cannot protect a regular ceiling speakers system. I'm going with the Klipsch R-28 home theater speakers, (recommended by Stereo East, an HT re-seller & installer in Frisco, TX due to the fact that the R-28F is a front firing speaker, and I have limited room behind the screen where I'm placing the front and center speakers) and their AW-650 outdoor has the same bass and tweeter technology which is a perfect fit.







I also build a test panel, using YzfBossman's methods with a slight variation. I went with a simple panel molding which is half the cost of the chair-rail. But still looks good all the same. I'll post detail pictures of the panel build next week, but here is a peak.



Here is the panel installed. The frame holding the material will simply slide in. And years from now, if i want to change the look, i simply take out the frame, replace the material.

Nearly Completed

The light at the end of the tunnel. Finally got a break from my day job and did more work. I completed the panels, build a DIY rack (of course it's a 100% build).....

Here are some additional detail pics of the acoustic panels. Next is for the carpet contractors to come in and do their thing.



Completed panel frame and nailed in:




Nailed-in panels, top is 2-3/4" thick to fit the 2" OC703. Bottom is 3-3/4" thick to fit 3" Roxul:


Panels filled in with OC703 & Roxul:




Here are the completed fabric panels that simply get pushed into their respective slots:



The work it takes to get that professional looking paint job..... Whew!!!


And here is what the finished product looks like (minus the new carpet):



Here is a couple of pics of my DIY rack. Will eventually build an enclosure for it using mahogany plywood and gel stain.



Power is in, and so is the receiver.... the rest getting on board tonite.
