I don't have any side view images as such because it's tricky to get any from the side - the aisles aren't that wide either side of the seats. This is the closest I could get - it's an old sketchup I made when I had two rows of four and only one set of steps in mind. I've deleted a seat from each row and extended the steps but it's only vaguely like what I finally built. You get the idea though
If you want two rows and are going to use commercial style cinema seats, that is the best choice as they are smaller and give you a lot more room, so you can fit more seats and/or have more aisle space. With the second row being on a riser (and only two seats), that gives you more room to walk as the front seats are lower.
You usually find for most people, ordinary seats have a lot of wasted space within the seat when you are sat in them because most people don't have 22" wide bottoms. A friend of mine is 6ft 7ins and fits in the commercial seats I have no problem. He prefers a bit more leg room, so although he has sat in both rows, prefers the leg room offered by the front row. I don't know many people his size though so he's more likely an exception.
Commercial eats have a minimum recommendation of around 36 inches from the back of one seat to the back of the next, but I chose 38". Plenty of room between rows (even for my tall friend). I can supply generic documentation if you go that route. My seats are older ex Odeon seats that I recovered. I bought them used from a company based in Essex. They do lots of renovations and have many seats, both new and old. I found them on eBay. The seats were £25 each. Newer seats will cost more of course. They're around 20" wide. I originally wanted two rows of 4, but for practicality settled for three in the front and two for the back. That lets people to see through the heads of those in front and allowed for a reduced riser - ideally it would have been a 14 inch riser, but went for 11ins (with a mid step like in the pic). Hopefully you won't have friends as tall as mine. Riser is wall to wall (safer that way), and only in the middle of the room for the seated area - that way I didn't have to make steps from the door after you enter the room, and allows more headroom. It looks and works better than the image suggests.
I haven't shown any speaker locations, but I have a speaker at each side of each row at ear height (so 4 side surrounds total), and my Atmos are placed similarly to yours. I have two rear surrounds for the 7.1 base layout (even though there are 9 speakers and not 7 for the base in actuality), and 4 for Atmos. I'm using identical coax speakers for surrounds and Atmos.
Hope that helps.
Is there any commercial type that use this?
holy moley
