Ceramic cones
Advanced technology for natural sound.

Hard ceramic is light, yet extremely rigid, making it one of the best materials for speaker membranes – it’s also known as Sapphire. 

Our ceramic cones have a high internal damping factor, because of a refined electrochemical process. The membrane also has a high material resonance frequency, meaning distortion is minimal; offering a level of clarity that is the holy grail for high end speaker cones.

Bass drivers
Low frequencies.
Low distortion.

The Cell bass driver units have long excursion, extremely low distortion levels and a hidden surround. Made of Aluminium sandwich honeycomb, the drivers offer rich, dynamic bass performance with a powerful presentation.

Cabinets
Crafted for strength.

We use specially selected, medium-density fibreboard with optimum rigidity to create high-quality, resonance-free cabinets. 

The shape and dimensions of the cabinet have been carefully considered to deal with reflections from the drivers: giving low resonance and diffraction control. The internal structure and bracing keep the cabinet rigid and resonance-free. 

Each cabinet is finished with precision veneer and lacquering. The lacquer is carefully built up of 7 layers, each hand-polished in between drying.

Crossover
Low order for
high dynamics.

We prefer to use lower order crossovers, as the higher order crossovers tend to limit the dynamics and details. Our second order crossover has been creatively designed to make the best of the dynamic range.
