The ceiling panel doesn't have to be huge. The first idea is to absorb some of the reflections from the speakers. If you draw out your space from a side view, you can try to calculate the midway points on the ceiling between the speakers and the seating positions. This is the old mirror trick, but without trying to get someone to hold the mirror on the ceiling while you move from seat to seat.
The second idea is to absorb some glare, this one is simple. Turn on a movie and take a look to see where the light is reflecting.
Just as a completely baseless guess, I might think about two panels maybe 75% of your room width by 2' across placed at the first reflection points would go a long way.

Right, I know.... I should just go an smash my face against a tree... I was goofing around today and created a list of things to do AFTER I'm "done"..... OMG why does this have to be so addictive?!?

Thanks for the ideas on the ceiling panel. I bounce it around in my head for a bit.... Thinking I may need to use some sort of fiberboard to mount the fabric to in order to keep it from sagging. A bit of spray adhesive and some sort of thin, rigid sound deading material. Kinda like a headliner in a car.

How about rigid foam insulation? Add a layer of Linacoustic, and cover with fabric for looks? Lightweight, cheap, and easy to get.

You can just wrap some fabric around some OC703 or equivalent and then hang them with these: http://www.acoustimac.com/rotofast-acoustic-cloud-anchor/

HEY!!!! Now your on to something..... daddy likes...

I was looking for something thin, rigid and easy to work with. I did a Google search for "1/2 Sound Deadening board". I found this stuff... BLUE RIDGE FIBERBOARD

I can see how it would be great in a build for the interior of walls. Just not sure how it would work as a sound deadening panel OUTSIDE of the wall.

I would bevel cut the edges (make it look nicer) and spray it with a headliner adhesive, then wrap the sucker with the DMD fabric and hang it from the ceiling with them "fancy-schmancy" RotoFast hangers...... What'cha think? Would it work or just be a waste?

You can also just mount the acoustic panel/rigid fiberglass to the ceiling using drywall screws and washers and then attach the fabric to the ceiling with a fabric track arranged around it. As long as you are not going thicker than 1", the fabricmate track will work great. Will need to go to QAI or another provider if you want 2". I am in the process of doing my ceiling now (about 3/4 done). I am doing 16 foot long strips of fabric, 60" wide and am having no issues with the fabric sagging. Looks just like it does on the wall, but it is a bit harder to do since it is over your head. Would be a bit more expensive than just wrapping the fabric, but I think it would create a cleaner look.

And, for the record, after doing this to my ceiling, I cannot imagine having a theater without fabric on the ceiling. I am using black FR701 and the ceiling just disappears in the room without the projector on (no mounted yet). Reflection will also be much less than a painted ceiling. I did not do any kind of treatment on the ceiling and it was not recommended by the designer. Mine is just fabric.

Sorry for the delay in responding. Holidays... rolleyes.gif

Thanks for the info. I would love to see a picture of your material ceiling. Maybe I am not understanding,but is you material attached directly to your ceiling?

I was considering using a 4" x 8" sheet of pegboard and backing it with either some of the low-profile carpet or heavyweight hardwood underlayment I still have. Then wrapping it with more fabric and attach it to the ceiling. From the ceiling it would be... PAD... PEGBOARD.... FABRIC.

I read that pegboard really isn't sonically any "brighter" than drywall. In fact, it is supposed to have somewhat of a diffusing effect and LFE filtering. Figure the pad would absorb /control what sounds get through.

Thoughts?

I'll take a picture and get it posted. The way I have attached is I am using standard 1/2 inch fabric track from fabricmate to hang the fabric, just like you do in the acoustic panels.

U 'da man. I would very much like to see the pictures. Now I understand how you did it, thanks for the details. Bet it looks cool!

I have been considering redoing my door and making some smaller panels for key reflection points in the room. If your ceiling looks as cool as it sounds, may be ordering a lot of the track.

Here is a shot of the ceiling. The flash is on because, with it off, the ceiling disappears. During a movie, there is minimal reflection...much less than "Mouse Ears" flat paint. My whole goal here was to minimize reflection and not draw any attention to the ceiling...this works great for that and it is relatively easy to do.

Sadly no, with the onset of 2013 I have been running like a mad man. Only to briefly stop and occasionally enjoy the Theater as it is.Which is approx 98% there. Just a couple of items still hanging around.

1. Finish the crown. I plan on painting the crown black and hang it approx 1/2" from the ceiling with LED strip lights behind it. Figure the 1/2" would provide enough "glow" and be close enough that a gap would not be noticeable in the day.

2. The equipment closet door. Need to finish it off to offer soundproofing and sound absorption. I currently have a layer of MLV hanging on the door, and if does a decent job for just 1 layer. Need a rigid board with very good sound absorption properties. Fabricmate has a product called recore, it looks like something that would work for my needs, but it is expensive. Looking for an alternative.
