Greensound Technology made its first appearance at IFA this year and alongside its Serac series speakers, the company was showcasing its latest offerings - the Luno and Cube subwoofer. Like all Greensound's creations, the Luno speakers are made from a pane of glass - this time curved slightly - that isn't just for show but actually vibrates to produce the sound that is projected from both sides to deliver "360 degree sound."

The floor standing Luno speakers are the most compact offering from Greensound to date, standing at 106.7 cm (42 in) tall with a base measuring 45.7 cm (18 in) wide and 45.7 cm deep, and a weight of 36 kg (79 lb). The company says this makes them ideal for hotel rooms, small suites, waiting rooms, medium-sized homes and - naturally - yachts. The accompanying Cube subwoofer is even more compact, measuring 45.7 x 45.7 x 20 cm (18 x 18 x 8 in) and weighing 18 kg (39.6 lb).

The glass speakers can be lit with optional colored LED lighting, while digital transmitters that plug into an amplifier's speaker output and operate wirelessly at 5 GHz do away with the need for running cabling around the room - or yacht. However, the speakers will still need to be plugged into a power outlet.

The Luno outputs 70 watts with a frequency response from 60 Hz to 17 kHz, while the Cube subwoofer outputs 125 watts with a frequency response of 30 Hz to 180 Hz.

There's still no word on pricing but Greensound Technology's European site says that the speakers will become available this month, so we should find out soon ... though it's pretty "clear" that they won't be cheap.

Greensound also has a U.S. site here.
