Hey folks. Wanted to close the loop here.
I went all in on six Sonance IS8 invisible speakers driven by two Sonance DSP 2-150 amps.
They sound great. My visible ceiling Kef 8 inch speakers I have in the garage driven by a Sonos Amp maybe sound better. Maybe. I mean seriously maybe.
The IS8s sound fantastic and I couldn't be happier. Crispy highs and super clear sound.
I originally drove them with Sonos Amps. The Sonance DSP amps definitely are worth the money. I installed an "EQ preset" file I was sent by Sonance support for the Sonance IS8s. I don't know if I can tell the EQ difference, but the Sonance amps certainly sound better than the Sonos Amps.
I used a great "mud guy" to skim coat them. I'd say that's super important here.
Also, I didn't bother trying to make a 5.1 audio setup. I'm just using them for stereo audio through my great room.
Three cheers for Sonance Invisible speakers. Please buy some so they don't go out of business and leave me hanging if they fail in the wall.
Cheers
