I'm a little surprised that the Sonance speakers were released with so little tech information about them, even physical dimensions, at least on the Sonos site and promo email about the speakers
I found information on them at crutchfield.com. Didn't see anything on the outdoor speakers.

Also surprised that there are no packages/sets with these speakers and an Amp, and possibly the Sub, available. Maybe it's still early, and the rest is to follow..
