I haven't gotten into the theater tonight. But here's some progress from last night.
I built a speaker frame out of a speaker frame kit from Parts-Express. I removed the nubs on the back that fit into the female socket fittings. The sockets seemed like it was going to be challenging to get the grills in and out. So instead I'm using magnets to attach the frame.
The frame certainly took some time and I have to believe there's a faster way. Was thinking of a metal bar on the top wrapped in the GOM and then another metal bar to add some weight to the bottom. Then magnets would hold the material taught vertically both at the top and bottom. My concern with this method is the edges may not always look taught over time unless they are attached to something and could possibly get snagged or frayed over time.
Any one else try the gravity method with magnets.
Overall the parts-express kit was easy to work with. I initially made some cuts with a hacksaw, but then just used a table saw for more precise straight cuts. The frame was hot glued together and then the material applied using hot glue. You really just need to take your time with the hot glue and keep pulling the material so it has a smooth edge. I started with the corners. Going from one diagnol to the other and then working towards the middle.
One thing I'll be doing with the next frame is adding the provided supports that the kit comes with in the middle. I can see a bit of bowing in the frame. It was most likely from me pulling the GOM to tight on the plastic frame. So next one, I'll be a little less agressive. I'll probably slip a small piece of black velcro on the bottom of the speaker frame against the fabric so I can pull the frame off the column easily.
Right now, I have screws attached into the back of the speaker frame that line up with the magnets in the female socket fittings within the column. I think I'll switch that around and put the screw in magnets on the frame and just a piece of metal in the column. Requires less presicion and lining up screw to magnet.
