Innovation continues through its use of materials. Its 3-way speaker system incorporates ceramic bass and mid-range drivers allied with a market-leading diamond tweeter, giving you full range sound, 20Hz to 100KHz.

The carbon fibre cabinets are constructed in one piece, making them large on the inside yet deceptively small on the outside. There is a bass reflex port underneath the cabinets.

Utilising its space this efficiently means it integrates into any living space, big or small.
