In the process of a new construction and am looking into installing speakers throughout the house. In the main living area I'm looking into the playbar with two additional speakers in the rear installed within the ceiling to create a 5.1 system. In regards to the Sonos Sub, can it be installed within a wall off to the side and if so how will this affect the sound and its performance. Not a fan of the subwoofer sitting in a corner or in view and looking for other options. I know you can place it under a sofa but that isn't an option due to our current sofa design. Thanks.
