Has anyone done much comparative listening between the various Tannoys? I've not had the opportunity having heard only my own (15" Golds) and various other later Tannoys, e.g. HPD, LRM, LGM, SRM, SGM, FSM types and some more modern domestic ranges e.g. GRF Memory, Canterbury SE over the years. Always in isolation, never against one another, and never in locations or systems I know well. I've never heard Reds or Silvers at all.
I get the impression from reading the Japanese sites (and it is they who know such things) that the 12" Silver is the sweetspot of them all. Apparently it runs the bass cone full-range, i.e. has the best behaved bass driver / simplest crossover combination and has a life and vibrancy the later models dilute to some degree. There certainly seemed to be a progression to heavier more rigid cones, increased crossover complexity and increased power handling as new ranges were released. Would be interesting to hear views from those who have heard many. I'd also be interested in views of 12" vs. 15" - I'd love to compare them and it wouldn't surprise me in the slightest if I didn't end up preferring the 12" - I'd expect the mid to be a little clearer, I'm amazed a 15" cone works at all at 1Khz!
