My Line Manetic Field Coils Speakers are 105db Sensitivity, Their are dynamic and yet smooth, musically invovling, My Classic Audio Loudspeakers are 100db Field Coils.
Both of these speakers to my ears give one dynamics as closer to live performance and as a result are more emotionally invovling and exciting to listen too. it does not bore you to death.
Been their and done that with low efficent speakers and high powered Tube or Solid State amps never again.
