Tannoy Canterbury 12

 The Canterbury 12 is a truly special loudspeaker made only to order with certification and personalised nemeplate. Both the Canterbury 12 and the larger Canterbury 15 use the classic Alcomax 3 high-energy magnet versions of the famous Tannoy Dual Concentric driver in either 12-inch or 15-inch chassis.

Alcomax 3 is an unusually high energy permanent magnet. The special iron/nickel alloy is doped with cobalt, aluminium and other rare metals to produce a magnetic material with very special properties. Alcomax 3 has a high remanent magnetism and energy product. In other worlds, it magnetises to a  high level and retains that unusual degree of magnetisation. Alcomax 3 is also an electrical conductor. These properties give the Dual Concentric drive unit using an Alcomax 3 magnet an exceptionally clean transient response and increased sensitivity.

 The Canterbury 12 employs a high performance 12-inch Dual Concentric driver in a braced birch-ply cabinet. Burr walnut veneers and solid walnut mouldings are used to enhance both structure and beauty on the cabinet.

Van den Hul bi-wiring is used through out. High frequency energy can be tailored through high current gold-plated switch blocks with controls for both treble energy and roll-off. Low frequency adjustment is through the Tannoy Variable Distributed Port System (VDPS)
