Luk.......One of the most obvious differences besides the cabinet dimensions and price points is the Kensington Gold Reference's 10-inch dual concentric driver system versus the Canterbury Gold Reference's 15" dual-concentric driver. Although the woofer sizes are different between the two models, the horn loaded tweeter is identical for both, a 52 mm (2”) aluminum/magnesium alloy dome with round voice coil. Also, according to Tannoy's published specs the Canterbury is 3dB more sensitive at 96dB when compared to the Kensington's 93dB sensitivity. Obviously the MC2301 will be loafing while driving either speaker.
There is a difference in cabinet materials between the speakers. The Kensington GR is constructed of veneered particle board with a high density birch plywood baffle and rear panel. The Canterbury GR is constructed entirely of veneered high-density birch plywood and solid walnut trim. The Canterbury's front baffle is 1" thick to help support the larger woofer.
There is also a power handling difference between the Kensington GR and the Canterbury GR. The Kensington's continuous power handling is rated at 125 watt RMS with peak power handling of 500 watts, whereas the Canterbury's continuous power handling is rated at 150 watts RMS with peak power handling of 600 watts.
Both the Kensington GR ($9,500.00) and the Canterbury GR ($30,000.00) have received excellent reviews.
