Hi all. First post after doing a lot research putting a theater sound system together. So far I will be doing an Arc and Sub. Unfortunately, due to my recroom design I will be using the Sonos 8” in-ceiling Architecture speakers and Amp for surrounds as opposed to the Era300’s.
My question is in regards to the Sonos Architecture installation manual. It states that adding an additional set of in-ceiling Architectural speakers will yield 7.1. Being an actual Sonos manual, can anyone confirm if this in fact the case and see any benefit from adding an additional set of speakers in the ceiling as described in the diagram (Fig. 3)?
