For my home I am planning to build in in-ceiling speakers in combination with the Sonos Amp.
Due to the low installation depth, I am thinking to use two KEF Ci160TR speakers in combination with one Ci200TRb subwoofer (to have a bit of bass anyway).
Unfortunately, due to the construction of the house, it is not possible to build in deep (er) speakers.
Would the system work nicely if I connect it as shown in the diagram below?
The subwoofer can be set to "Mono Mode".
