I have been looking into this since if you can’t put a huge amount of speakers in your home this is a good alternative. The Yamaha seem to have the high-end which is the YSP-1100 and the medium which is the YSP-900. And Mirage has the UNI-Theater which also caters to this type of speaker. These types of speakers usually have the ability to adjust their output to the size of the room with their technology so the output becomes better, but what differentiates them is which ones does it better. I curious to see which one does it better, but you have to find the right application for it.
