The CTS/Motorola tweeters seem very consistent to me. I just buy them. There is a KSN1025 (2"x6", 1800 hz) available from Radio Shack, lacks the high power protection, but is still a sturdy unit, for those of you who want to check them out, experiment right away.

I agree with a posting elsewhere on here by Wayne that the harshness many hear is a mismatch of levels... these tweeters are more sensative than the advertised rating. And he gives a solution to this problem.

Mine was different, I used the 8 ohm resistor across the terminals, then used an L-pad, and used a 12 uf cap on the hot lead coming to the L-pad. Before discussing with Wayne the SPL on these, I had already dialed my L pad down -5db to match the 1165a's more realistic 96 db SPL to my woofers' 92 db SPL.

I see no apologies necessary over using these "cheap" tweeters... they perform!
