Uni-Q driver array

Sweet, spacious and true, wherever you sit.

Thanks to the latest computer modelling techniques, years of painstaking development and a dash of design genius, the new iteration of the Uni-Q concept packs a formidable complement of design innovations. Based on the state-of-the-art HF driver developed for Concept Blade, the Q boasts a much larger (25mm/1 in. dome) tweeter for increased sensitivity and distortion-free power handling. It plays as loud as it plays true.

Advanced bass technologies

Deeper, tighter and more accurate bass.

Featuring rigid new aluminium cone technology just like the Uni-Q array, the Q Series advanced bass driver is a tour de force in its own right. A die-cast aluminium chassis rigidly locates the high efficiency vented magnet assembly to prevent unwanted resonance, and the large (50mm) voice coil ensures impressive power handling. Its musicality is impeccable: seductively tuneful and well controlled, and on the floorstanding models, complemented by dedicated front-firing auxiliary bass radiators (ABRs).

Total system design

A holistic approach with no compromises.

The performance envelope of these sensational new drive units is so generous that the signal needs minimal intermediation - simple first order crossovers are all that's required, as you can tell from the transparency of the sound and the inaudibly fluent transitions.
