I’ve done a few in-wall and ceiling speaker installs using Sonos Amps. Except for when there is an obvious stereo configuration (like speaker on the left wall and right wall relative to a seating area), I’ve been using the Dual Mono option which seems to sound better.
I just recently did an outdoor zone that needed some additional power. So I’m using a Sonos Port + third-party power amplifier. It doesn’t seem like the Port has the mono option, and neither does my power amplifier. I’m also using the coaxial output to the amplifier, so I don’t think I could use a third-party mono converter device without having to compromise on resolution.
Thought I’d see if anyone has any other ideas for workarounds. Or perhaps someone from Sonos could weigh in if mono has been considered for the Port’s roadmap?
