You can also make these sweeping bends by patiently heating the conduit while rotating the pipe and continually moving a heat gun (or more carefully, a plumber's torch) over a section of the PVC pipe until it softens enough to stretch without kinking. Hold it in the custom shape and splash cold water on it to speed up the hardening process with your third hand. I have bent up to 4" PVC pipe this way to get around obstacles where elbows would not have fit. This also eliminates the joints that the fish can get hung on.

I would have made the stretched-fabric panels removable wherever there was a speaker behind them. It was a technical challenge to do this, so I opted not to. I believed that it was unlikely that there would be problems with the surround speakers, since they are passive, so no electronics to fail, etc. What we did do was to really pay attention to how they are mounted, ensuring there was no way for the speaker to vibrate, or for the speaker wires to contact the cabinetry or any other structure and vibrate.

Well, I ended up with a buzz in one of my surround speakers! So, I had to take the fabric down, which will require expert assistance to put it up again. It turned out that there was a loose screw on the back of the speaker, and it allowed the PCB for the speaker crossover to buzz when the speaker was energized with a particular frequency range.

After a build like yours, to end up with such a dumb problem is a real shame.
More proof that sh*t happens.
Duct tape won't work?

It is a bit vexing, but right you are. "Stuff" happens. We did do extensive shake tests and tone sweeps before putting the fabric up, so I suspect that that screw either backed out a bit, or maybe the PCB was stuck on the standoff that holds it and eventually popped free.

I will be using some superglue on those screws before I put everything back together.

What fabric system did you end up using? I have tried/plan to install the fabricmate track system, its really easy to get fabric in and out of it if you do need to replace something behind it. You just pull the fabric back out, then use a pizza like tool or a thin tool like a putty knife to push it back in, doesn't require any thing special to put it back in.

I was thinking I would use Fabricmate, but saw their price is up 50% per piece, so I should have bought a few months back. Now, I am thinking 3/4" plywood strips, with 1/4 round on the edges, but velcro them to the wall for easy removal.

I don't know what it's called, I'm afraid. I had it installed professionally. The tracks are in two pieces that snap together and hinge open on one side. You affix the fabric to the other side where there's a sticky area, then snap them closed, which puts the tension on the fabric and clamps it in place. I've attached a photo of a sample piece.

Yeah, that one does look more complicated. well hopefully you won't have to take it off to much anymore

Let's hope not! It's not too hard to take off with the proper tool. But I'm not willing to try putting it up again myself, especially on that panel with the cutout for the light fixture. The pros will do it next time they're in the area for another client.

I have several. A few that come to mind...I'm sure I'll post more later.

1) Build a basement in my next house. A basement was out of budget for this house but I definitely want one in my next house. The upstairs theater is not that bad for my family, however I really envy the awesome basement theaters and recreation spaces.

2) Make the riser at least 12" tall. Mine is 10" and if reclined in the back row the front row seats (if not reclined) set ever so slightly up at the bottom of my view in front of the screen. Most "non theater geeks" people would probably not notice, but its enough to drive me mad.

3) Make the ceiling taller. My plan called for 8' and I had plenty of space to add another foot or two, but didn't to save money. It would have been worth it to add an extra foot and I never even discussed the cost with my builder.

4) Make a bigger component closet. I personally, am not a fan of the visible equipment racks and like have my components hidden. I put in a 4'x5' closet which is more than enough room for my equipment but it would be very nice if I had more room to walk in and move things around easier when it comes to setup, etc. Not to mention, I like to store all of my media in there as well.

I had the same problem with your #2 . I build a small "riser" just for my second row. 2x4 with leftover 3/4" ply. Covered it with black carpet, kinda like the stuff to cover boat trailer bunks. It gave me the boost I needed.
