Monitors with Built In Center Channels
Center channel placement is an issue for me in one of my HT systems that is located in a built in. Currently the cc resides above the TV. The cc takes some space as well, limiting me to a 55 inch screen where a 65 inch would otherwise fit. Dialog improved considerably when I added an AVR with room correction but I was reading a review of a Sony OLED with a built in cc. As I understood it the entire monitor is a cc with the sound emanating from the screen. Theoretically this should be possible with either planar magnetic or electrostatic type membranes but the review and what I Googled are fairly mum on this. Does anyone have experience with such a monitor?
