As we design and manufacture our own drive units entirely in-house, we are able to design the perfect driver for each situation.
Our unique ‘Tri-lam’ technology produces drivers capable of delivering spectacular bass performance with distortion lower than
any other drivers of similar size.
The aim of any large format driver is to have a linear pistonic motion with the minimum cone distortion and break-up possible,
even when driven extremely hard. Our ‘Tri-Lam cone achieves this using a combination of Carbon fibre and glass fibre.
The cone material is a composite construction comprising of a hydraulically moulded and thermoset lamination of three layers.
The inner layer is bi-directional carbon weave, the outer two layers are a bi-directional glass fibre weave. In addition, the outer
rim includes ‘rim-edge stiffening’ to further reinforce the resulting cone.
The result is a cone that is light yet incredibly strong, ensuring very low energy losses, even at extreme levels, and without the
‘muddy’ delays associated with lesser cone materials.
