Non toed-in speakers/additional options?
In my particular situation the screen wall is an existing wall shared with a basement pantry and tool closet. Because of this I have a lot of leeway on the types and depths of speakers I can use. I wanted to retain the existing flat wall as a baffle wall, but It's not critical that I stick with shallow 4" deep in-wall speakers. It also isn't critical that I enclose the backs of the speakers. The primary attraction of some in-wall speakers, like the SCL-7 and the Monitor Audio IDC models, is the built-in ability to have an offset while keeping flush mounting on a flat wall.
I had been under the impression that infinite baffle setups are preferable if they are practical for a situation, and in my situation I can leave the backs of the speakers completely unenclosed instead of in a stud bay. I thought this would have benefits in less internal reflections within the speaker, less resonance (ports/etc), and less back pressure so the drivers can move more quickly and freely. Is my thinking wrong?
Toe in is not necessary with these speakers, given your use case / audience size / geometry.
A sealed stud bay IS how they are designed to sound best, and that is definitely what I would do. If you want to consider other designs, please consult with JVC via your dealer to get the engineering requirements for other installation approaches. Chances are good, the best performance will be to use them as designed (in a closed stud bay) but their engineering team may have recommendations about alternatives.
Vertical dispersion/second row
I'm planning to optimize sound for the main row as the second row will be truly "secondary". As long as they can understand the dialogue and enjoy some subwoofer drama, I'm sure everyone back there will be very very happy. My plan is to have the tweeters vertically centered behind the screen, and first row eye level around 1/3rd of the way up the screen.
I would try to position the tweeter at the same height as the primary listener’s ears. What you describe sounds like the tweeter will be noticeably higher than that, more like at the ear height of the second row. That will compromise the sound for the front row.
