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)
