Agree, the Kensington and Canterbury models are both wonderful, yet I’m very happy with my upgrade to Canterbury :) And yeah, the Definition 10A was a real head-scratcher, sadly.
Sorry - I just remembered there was some discussion (audiokarma?) out there concerning Tannoy’s change over from alnico to ceramic/ferrite magnets, and I believe there actually were some Tannoy driver versions which married ferrite magnets to a pepperpot, which contradicts my prior response. I’ll try to look up what model that might have been (it was after the HPD). Looking again at the pepperpot cross section, it would probably be OK to use a short ferrite magnet with a long pole piece to make up for that...going the other way though - the tulip waveguide might not have enough room to work with the weaker & larger alnico magnets needed? Either way, the ferrite + pepperpot configuration is not made today. I'd also love to know whether that's due more to market demands (people in the market for classic Tannoy sound more often demand alnico) or due to Tannoy's opinion on the sound quality.
