Hello Everyone,

I just ordered a pair of Sonos Era 300’s to run as rear speakers for my surround sound.

Please excuse the condition of the house, we just had a flood and I’ve been tearing everything out.

Right now we have a Sonos arc, Sub Gen 3 for the front and I have recently acquired a Sub Gen 2 for behind the couch. Up to this point I have been using two Sonos Play 1’s as rears which will move to a different room.

The couch will be placed in the blue rectangle, and is 43” tall. We are building a half wall between the rooms outlined in red which will be 40” tall.

The rear sub will be placed behind the couch as outlined in green.

As for the era 300’s the placement is a little bit more tough, as you can see on the left side is a light switch and the mantle to our fireplace, so realistically I’d have to place it above this, and I can match it in the opposing corner however it would be about 6” further back.

At this point because of the placement it will obviously be above our heads as well as behind, but Im thinking of installing them upside down in the green circles.

What are the general thoughts about doing this? I’ve been reading that inverted mounting is now supported with trueplay is that correct?

Thanks everyone!
