When I rebuilt my screen wall I found a fabric at Hancock Fabrics that resembled the SMX ProPanels so I decided to use it for the panels surrounding the screen frame.


Here are two pictures comparing the Micro velvet to GOM FR701 (AKA the burlap)


First no flash:





With flash:





I don't have any test equipment to test for Acoustical transparency but I can do a blow through and shine through test. Here is the shine through results draping the fabric over my monitor:


GOM FR701:





Micro velvet:





I've been very happy using the Micro velvet. It is darker and a little "classier" than the burlap. It matches the screen frame and masking panels perfectly and makes the screen look almost like it is floating in mid air. With only the sub behind the fabric I can't detect any difference in the audio.


The fabric is this one.

Hancock Fabric Item# 128157


Hancock will honor competitor coupons and I used a JoAnne's 50% off any one item coupon successfully at the store.


Comparison of SMX screen, Pro Panel, Frame, Micro Velvet, GOM Crystal blue. Left to right.





Notes: the micro velvet is at an angle to the camera. the Pro Panel is showing some reflection back from the screen. Under different lighting conditions the Pro panel actually looks darker than a swatch of the Micro velvet so I am now convinced that they are only nearly identical.


This picture really surprised me because I can not see a difference with the naked eye but when I look at the LCD viewfinder I see this difference:


Would you suggest using this for wrapping the screen frame too?

Do you know any place that sells 6" wide strips... I would like to go with one strip per side. I need (2) 16', and (2) 7' long.

Great build, some good inspiration in there! I also don't have a practical back wall on which to mount surround back speakers so am going to rehouse a pair of Linn Trikan speakers Triad style to fit in ceiling. I'm just wondering about how to attach a grille at the moment.

I've already made some 4" deep housing to convert 3 other Trikans into slim hang on the wall speakers for the surround and centre channels.

I just stapled fabric to the ceiling and covered the staples with molding.

BIG - are you thinking of retrofitting ceiling speakers into your theater for the new object-based audio formats?

no but I have a design modification of the Volt series that I need to get down on paper and post over in the DIY speaker section. I think it would solve many of the challenges of implementing Atmos.

Very simple, add a layer of 5/8 DW with GG to the back and sides of the speaker.

Make a second front baffle with a one inch overhang (past the DW) all around. Attach with GG and screws

Cut hole in ceiling, Glue/screw/caulk the speaker with it's own "backer box" to the double layers of DW

Fashion a fabric frame that sits flush with the ceiling hiding the flange and speaker.

Result a backer box mounted speaker protruding no more than an inch from the ceiling. Use a coordinated fabric color.

Plan where these go in advance to make sure you have clearance between joists.

Would these need to be aimed (tilted) a bit toward the LP? Or is downward firing going to be sufficient for Atmos (I know a lot of questions and not a lot of answers with respect to Atmos).

I know very little about this, but adding another layer to the speaker baffle may require a change to the crossover. If there is a demand for them, they may be able to build them with a larger baffle just for this type installation.

Dude, are you made of leprechauns? Cause that was awesome!

Good point, there would be two factors at play. First pulling the woofer forward 3/4 inch would increase the internal box volume by about 5%. There are obvious ways around that by just substituting a bigger front baffle, or adding a block of wood inside the speaker. But maybe larger is a good thing? Second mounting the speaker in ceiling (or wall) will result in some speaker boundary issues than may need crossover modifications. Maybe the DIY SG design team can address that.

5% change in box volume isn't much to sweat...

Speaker position in the baffle is what I was thinking of.

Are you mounting yours in a baffle wall ?
