Thanks! I rope caulked the horns of my Heresy IV in an effort to reduce a bit of resonance or sibilance and subjectively it seems to have worked. After caulking I played many of the songs that had some kind of sibilance (James Taylor, Norah Jones, Ella Fitzgerald, etc.) and it no longer bothers me. I'm glad you were able to measure a difference but looking at your charts makes me wonder if the green and red are mixed up? I hear less treble energy after caulking the horns. Regardless, I prefer the sound and seeing a difference in the measurements makes sense. Many thanks for sharing.

Thanks 001.

Can the titanium in the Heresy IV tweeters be replaced with a poly diaphragm? If so, which one? TIA.

I have this beautiful Dennis Had Inspire Sweet 807 amp. Great match with Heresy IV (all Heritage should be great). Back in the 1990s the Cary Audio gear I purchased stopped me from upgrading. I rotated thru lots of gear back then. I still have the Cary Audio amp/preamp and use it in the basement system with DIY speakers. Now the Inspire amp has stopped me from upgrading again (had three amps prior). Inspire upstairs, Cary Audio downstairs. I’ve compared the amps and find they sound similar but on direct comparison the Cary sounds a bit fuzzier. The Inspire is crystal clear and focused.
