- Exclusive cone is moulded from air-dried cellulose pulp properly impregnated with polymers, in order to make it waterproof, ultra-stiff and quite light, therefore it is stable even under very large sound pressures.
|
- The surround‘s butyl rubber is chosen for its wide operating temperature and for certain of a long term good elasticity.
|
- Progressive wave opposing double spider is made of tissue impregnated with special resins, to keep the right shape and elasticity for a very long time, even under heavy load.
|
- Sandwich voice coil is wound on both internal and external sides of a four inches heat resistant fiberglass tissue former: this technology assures a very high power handling and allows linear and fast excursions.
|
- Special lamellar shape of the black aluminium radiator provides the right air compression to reach good ventilation and increases the thermal sink.
|
- Strong aluminium die-cast basket, with an aerodynamic profile, assures the cone’s high excursion and supplies a right air-cooling, to reach the lowest acoustic compression.
|
- The impressive magnetic system provides the very high flux necessary for the perfect control of cone excursion.
