Teenage Engineering, a Stockholm based studio known for their simplistic industrial design, have recently unveiled the OD-11 Cloud Speaker — a wireless speaker that allows music to be streamed from cloud services. Combine this with integrated WiFi and an optional magnetic wireless Bluetooth volume remote, and you have yourself a great cloud music experience.
Inside the (26 x 26 x 26 cm) minimalist cubic form, you will find a 100w class D amplifier with filters and a DSP in an attempt to deliver the best possible sound.
Certainly a high-end product at $800, but it does appear to be an impressive piece of engineering and design.
