Your home Stereo/sound system/s? What did you buy, how much, and why did you buy it?

Nice audio. The room is not a HT, just a living room with many sub-optimal features. These speakers would probably spend more time playing background music to someone 20' away off-axis who doesn't care than playing movies, but I want the ability to be there. $3k would be the top-end of what I could do now for those front 3 speakers, but I'd rather wait a bit and see if I could manage ~$5k in about 6 months.

Most in wall speakers are less than $3k for the front three unless you're looking at ones from M&K or Atlantic Technology. Something like this ($1300 each + $200 for the box that goes in the wall for it). For example Polk's most expensive in-wall is $500.

You definitely don't want ports. Those Polk look like they are intended to fire into the open wall. That's not really feasible if you're putting them in a cabinet. I guess you would want to make a sealed box that's the volume of a typical 2x4 x 8' stud cavity. Something with a sealed back like the Def Tech UIW RLS II or recommendations for an enclosure volume is probably better. Is your cabinet going to be wall to wall floor to ceiling?

It is floor to ceiling and 2' deep but only 17' long (room is 33' long). I could easily reproduce the shape and volume of a standard wall cavity if that is what the speaker has been optimized for.

Shape doesn't matter. Interior volume does.

Good to know. While I could have replicated the shape, not having to makes it way less awkward.

Shape really doesn't matter? Even funny angles and stuff? I've read speaker design summaries talking about 45-degree this and that...

How about the space for the Sub? I've allocated a cube 24" wide, 24" deep, and nearly 30" high with almost the entire front open (covered in speaker fabric). At the moment I only have the entry-level Polk sub (PSW10) to toss in there. Should I worry about reinforcing the sides? Sealing it?

Thanks for all the help on this stuff!

That depends on what you're trying to do. Are you simply making an spot to place a commercial subwoofer, or are you planning to build a DIY subwoofer into that spot where the enclosure of the speaker is also the structure of the cabinetry?

At the moment I was planning on the former, but eventually will want something bigger, and was considering the latter.

Well the requirements are different between the two methods. Building a sub into a fixed cabinet is not a good idea since placement can make a big difference in output and frequency response at the seats, and it's not moveable when it's built in.

Gotcha. Well, the location is certainly fixed. With that in mind, I'm not sure what would be done with even a store-bought unit to "fit" that location.

Well, there are two approaches. Leave it open to the whole inside of the cabinet structure or wall it off. I'd probably favor the latter.

My brother-in-law is planning a long attic room with a projector on one end and the screen in the middle. He'd like the screen to work for both front and rear modes. Any recommendations for a material that will look good from both sides?

Yup. Long room, projector on one end, screen in the middle. Same side as the projector is a bed, opposite side is a rockband setup. Basically he wants the image to look decent from both sides.

So from which side is he going to watch the image reversed?

I'm not aware of any sort of screen material that will do what he wants.

That isn't very well suited for rear projection per the description. I think you'd be better off with a rear projection screen and a motorized roll up front projection screen that comes down in front of it.

If you needed to run speaker wire over 100' from the amp to the speaker, what speaker wire would you use? Shielded? Larger Gauge?

What if they wanted a volume control on the wall much closer to the speakers than the amp? Is there something that can control an amplified signal?

Ordinarily I'd send the signal via fiber (either TOSLink or HDMI) to something close to the destination and put an amp in there, but that isn't possible in this case.

Science says you'd need a couple football field lengths of speaker wire before there's distortion significant enough to measure due to attenuation. Just run long cables and be happy.

How many watts are you going to running down the cable? Unless it's hundreds of watts (nearer the 1kW range) 12ga wire is fine.

On the volume control I'm not sure. You're probably better off finding a way to remotely control the volume of the amp with IR extenders or similar rather than trying to find some sort of remote attenuation box.
