A pic is worth a thousand words!
I've attached an initial rough layout so you can get a better visual of what I'm working with. Still very much a work in progress. The "main" portion of the room is octagon shaped, with another couple of feet on the front wall and each side wall behind AT fabric for needed acoustical treatments. Speakers placed along the larger circle equidistant from center listening position, visible within the room boundaries.
Screen another couple of feet into the room in front of the visible "wall", leaning towards more of a free standing screen (could walk around and behind) than one actually framed into a larger screen wall, but still early and my taste may change.
The length from physical hard front wall to rear wall is about 45', just over 40' to screen from back wall. But that rear smaller rectangular extension of the room will probably contain acoustic treatments (absorption or diffusion or a mix) for the last 4-5' of depth. So the bar seating is a little under 30 feet from screen, and to be honest I don't mind sacrificing screen size for bar seating. First row center about 11' with a 55-60 deg viewing angle at 2.35 width of 160".
Front corners are large sub/IB "enclosures", rear corners flanking the bar seating area a combination of equipment closet, lobby, restroom, walkway, etc.
In addition to PJ placement issues, I'm struggling a bit with seating. Its a large space but the ceiling height complicates things. This is under the roof line, so the very outer boundaries of the room sides and front are ~6' knee walls, sloping up to ~8' at the octagonal AT boundaries, higher still centrally probably with a stepped shelf/riser look to disguise part of the slope and hide lighting and more treatments. Highest point could be 10-12' depending on how wide I want it, all of the bar area ceiling height can be 10-12 feet if needed but I would consider stepping that down to a lower soffit height running the perimeter of the octagon for PJ mounting (right over the bar itself).
The biggest issue is riser height. My current layout needs work, sightlines from the second row are a bit compromised with just a 12" riser, but the entrance door (top left of this overview, just left of the bar) enters under some portion of the sloped ceiling and may be under an 8' (from front floor level) soffit, so just 7' headroom with a 12" riser. I think 7' is OK, but any lower isn't, so its limiting the riser height.
I could do a multistepped riser (one shown is placeholder), going down to the front of the room, up to 2nd row. Could do up also to barstools but don't think it is needed at bar height.
It's a pretty big space, would love to have an even larger screen, but then first row would need to move back. Can't really do that and keep speakers equidistant as I'd like to (speaker radius would grow if screen is fixed and center point moves back, and as large as the room is the speaker distances can't increase much more). L and R at 60deg spread, will either be just inside or just flanking screen edges, not decided.
Would consider three main rows of seating, but I think screen would have to be bigger to not look too small from third row. So for now, going for more seating across. Seating shown is a placeholder, may consider squeezing 7 across front row and same in 2nd row.
I guess you could say this space deserves a huge screen and $50K PJ, but I'm working with it as essentially a 30' square with great width, space to hide room treatments, and some overflow bar seating area.
You may also say it deserves a professional design firm's attention. It may get that, but for now I've got time to play, and honestly I've "been there done that" on the audio side and my ideas quite frankly aren't in the mainstream. But the video side I'm much less experienced with so all thoughts are welcomed at this point!
