Wide vs long room
I've seen various posts on here about this type of discussion, but it seems like most of these were pretty extreme cases (like 10ft by 25ft for example). So my room isn't as extreme, I'm looking at a room that is 13ft wide by 16ft long. Originally plan was to orient the room lengthwise, but the type of furniture I'd like to put in there won't fit in that orientation (its a modular media room sofa comprised of six pieces that is 11.25ft wide by 7.5ft deep, so like a big rectangle). If I orient this couch to go with a long room, I have very little clearance on each side and I'm worried it will be too close to the side surround speakers. Plus there are ceiling rakes on a few sides (its an attic conversion) so the clearance will be an even greater issue on one side.
If I rotate the room to be wide instead of long, I'm getting a solid 2+ feet of clearance on all sides. I'm not doing a projector or screen, probably something like a 77" OLED, so I believe I would have adequate viewing distance from the screen. I just wasn't sure if having a wider room would cause issues with surround sound. I'd like to squeeze in 7.2.4 if possible, all in-wall except for the subs. I would either have a media closet (coming off of this room on one side) or an in-wall media cabinet/rack in the room. Just want it to be as clean as possible.
I've done some rough sketches, and visually it looks like it could work, but I honestly not sure.
Any input is greatly appreciated, thanks!
