Difficult Living Room -- On-Walls on Ceiling?
I've perused this forum quite a bit but still don't know what to do about my new living room. It's large, and the shape is very unhelpful for speaker placement. Generally, it's in the shape of a capital "L" with the length from the top of the L (where the TV will sit) to the bottom of the L being about 30 feet. On the left (long) side of the L are two semi-circular window alcoves, with an 18-inch flat wall between them. On the right side is a hallway and small wall, and then the room opens up in the bottom right to the open floor plan kitchen. I'd say the width is maybe 20 feet from the windows on the left to the small wall on the right, and the kitchen would stretch that another 12 feet. The floor is hardwood floor, and the ceiling (which varies from 8 feet to 10 feet depending on the ductwork for the HVAC) is shallow so there's isn't a lot of room for in-ceiling speakers. So, it's a large room with an odd shape and nowhere great to put equipment. The goal (per my wife) is for the TV and speakers to be invisible; this means no floor-standing speakers, no bookshelf speakers, nothing that protrudes too far from the walls, etc. I can buy the subs later, as we think those can be hidden easily enough. I don't need or even want 5.1 sound, as the speakers are just for listening to music (80% use) and hearing the TV better when it's on (20% use). I would expect that I would just have sound pumping equally to all speakers, unless some are larger than others. Volume will generally not be an issue, as I just want a large soundstage with diffuse sound so that the speakers are invisible to the ears and the eyes. I don't care if sound doesn't travel well to the windowed alcoves, as those are unlikely to be primary seating positions. The only wall I can realistically use is the small one between the two windows, and there I'd need a speaker that's not black (it would clash with the decor). The ceilings will be white. The absence of usable walls has me considering two options:
Option 1: Place some sort of bipole on-wall speaker on the flat wall between the round alcove windows, and perhaps place another bipole or two on the ceiling. I'm looking at something like the Triad On-Wall Gold Surround, as it seems like it would give diffuse sound but can come in various colors. Maybe I get one or more of these and place them on that short wall, plus a few on the ceiling?
Option 2: Place a number of smaller on-wall white speakers on the ceiling where the ceiling meets the wall. I'm thinking something like five Revel Concerta M8 speakers in white, placed throughout the room and angled towards the living area. Hopefully with five of them the sound would be diffuse enough that the ear wouldn't pick out any single one.
I'm open as to amps (haven't bought yet), and budget is generally fairly open given the handicaps here. I'm curious to hear what people think of the options (and speaker recommendations) and whether I'm missing any other option, given that I only have one 18-inch flat wall and the ceiling to work with. For example, am I being overly restricting in insisting on bipoles (or dipoles) for the first option?
Appreciate hearing your thoughts!
