The 8” cone is a propriety cone material using a laminate of different polypropylene films and adhesives. This creates a stiff but still dampened cone that will remain stable even under very large sound pressures. A long, 4 layer, 1.25” voice coil housed in a very narrow gap, optimizes sensitivity, power handling and transient response time.
The Aluminum Short Circuiting Ring prevents motor distortion in the voice coil. At the same time, this acts as a heat sink for the voice coil, reducing power compression. There are 2, lightweight adhesive bonds on
the Dust Cap. This way the dust cap and cone will respond to every coil movement accurately and without breakup.
The midrange in the Kontra reproduces the critical frequencies from 100Hz to 3KHz. There are 2 midranges per speaker - aligned around the tweeter in a controlled directivity design. This allows the sound to interact minimally with the floor and the ceiling, and not loose sensitivity over long distances. The midrange is a unique component, with a multilayer cone material and a dual magnet system.
