Voxativ Fullrange Hybrid Fieldcoil Driver AC-XHB
The AC-XHB is a fieldcoil driver with added Neodymium magnet, a hybrid system.
Additionally the coil housing is manufactured from a cobalt iron alloy (Permadur) that has special magnetic characteristics.
With a value of max. 2.4T cobalt iron alloys have the highest saturation polarization of all the known soft magnetic alloys.
Combined with a Neodymium ring magnet this unit delivers 24,000 Gauss in a 10mm magnet gap - the strongest magnet motor ever build.
The suspension of the AC-XH is made from goat leather that will stand for a minimum of 20 years. Actually a stroke of 10mm is possible. This is combined with a cone made of real wood.
The audio impression is wonderful: All frequencies are reproduced naturally in balance, basses are stable and tight, mids are clear and differentiated and highs always remain transparent and soft.
As a power supply the battery based system is recommended.
Price is for a pair.
