Man that looks like a really open floor plan. Good for design, not so good for acoustics, especially LFE Sound waves don't care about where arbitrary lines are drawn on a floorplan for where rooms end - they care about where the walls are. If I'm reading this right, your "room" is actually the great room, kitchen, cafe, dining room, foyer, heck even the stairs. That's maybe 7500 cu ft. Are the arches to the DR down to the floor, or just "windows" to the great room? The more wall there the better for acoustics. I'm just not sure any sealed sub can really pressurize that space. They will sound OK, but I don't think you'll feel much unless it's near field, sitting next to your couch. I don't think you'll be wowed by the experience. Just don't buy it until after you move in, so you can try it out and have the 45 day return policy.
Thank you for the reply. I was concerned when we visited the build site again and this was probably the first time I visited after doing some research/looking around for a sub, which is what lead me to posting the floor plan. I was originally planning on sticking the sub in the bottom right corner of the great room so it appears some what "hidden" when you walk into the area, so it would not be considered near field. Those are indeed archways to the dining room. It seems like I might just be better off going with a PB vs SB. I could potentially do dual SB but it goes against my "smaller" footprint focus.
