[* black] Want more specs on the speakers? So did we. Since Sonos is hush-hush about them, we decided to do some poking and prodding of our own. Here's what we came up with:
[* red] 2 ¾" mid-range drivers (2" [http://makeprojects.com/Project/Styrofoam+Plate+Speaker/37/1#.UQA1NaGltOR|composite speaker cones])
[* orange] 4.8 Ω ''measured'' impedance
[* yellow] 1" silk dome tweeter
- [* green] 3.7 Ω ''measured'' impedance
-[* black] Why do we stress that those impedances are measured? Home stereo speaker impedances are usually 8 Ω, but will read lower than that on a [http://www.ifixit.com/Tools/Digital-Multimeter/IF145-035|multimeter].
