Klipschguy Posted March 21, 2020 Share Posted March 21, 2020 The K77M seems to be a little more efficient than the K77. Is there a difference in the sensitivity ratings of these 2 tweeters, or is it possible the old alnico version have magnets that are weaker due to age?

garyrc Posted March 21, 2020 Share Posted March 21, 2020 If anyone has a chart or something that compares these, I'd appreciate a comparison of the sensitivity and subjective sound of the T35 round magnet, K77, K77M, K77F (and D). Thanks. Quote Link to comment Share on other sites More sharing options...
