I came up with an idea that I'd like to try out... Curious what you guys think.
I have a split-level house with the kitchen and living room upstairs. The LR is medium size, tall ceiling, and will have seating on maybe three of the four walls. There's a fireplace, lots of light, and is generally a great place to hang out alone or with company. I have no intentions of putting a TV or proper stereo system in there, and mainly just want music for entertaining, casual listening, background, and so on.
I'm strongly considering ceiling speakers. The attic is directly above, so enclosed cans would be fine. But with ceiling speakers, especially when there's no "correct" orientation to sit, having good left-right imaging seems somewhat of a burden to try and achieve. I would still like the sense of spaciousness (in the sound) but I'm far more concerned with something that sounds 'nice' rather than 'accurate'.
Given that, I thought of having a center speaker in the middle of the room, and then maybe two others flanking it, or four in a box or diamond around it. The four would be tuned to sound as loud in any given area as the center, and instead of using L and R feeds, I would put the stereo audio through a Mid-Side encoder and send the Side channel to the four.
For those of you not familiar with M/S, it's basically like the Center and Surround channels from Dolby Pro Logic, but contains 100% of the audio and can be converted back and forth losslessly with simple mixing and phase inversion.
