The innovative speakers, which are well-suited to use with computers thanks to their USB input, use NXT's DynadUSB module, which combines a high-efficiency amplifier and 4cm square Balanced Mode Radiator panels.
Despite being USB-powered, the speakers manage to deliver 15W per channel thanks to an amp design said to be up to 20x more efficient than competing designs.
Clever power rail switching meaning it can work on low voltage most of the time, and then boost power when the music requires.
The QSB speakers, which come complete with all cables and a travelling case, will be on sale online initially via Dixons and Pixmania, with other retailers, both online and 'bricks and mortar', to come soon.
