25 mm (1") High-end titrate for the high tone range from 2000 Hz.
By means of a specially developed process technology, the enormously hard titanium foil can be shaped into ultra-light calottes which, together with the strongly damped supranyl queue, allow a linear and partial oscillation-free frequency response.
Due to the enormous magnetic induction in the air gap filled with ferrofluid, a high efficiency and a high load capacity can be achieved simultaneously.
