Teenage Engineering made a sonic boom when it launched its OP-1 pocket synthesiser back in 2010. Right here at CES 2013 it's introducing a new audio curiosity -- the OD11. The firm is calling the device the Cloud Speaker and inside the (26 x 26 x 26 cm) cubic form you'll find a 100W class D amplifier with WiFi and Bluetooth 4.0 connectivity options. There's more to this geometry than just a speaker, though, as there are some internal smarts (filters and a DSP etc)
