radiogram Posted July 8, 2021 Author Share Posted July 8, 2021 @Pondoro Not much really. The K22 woofers were replaced with K28. The original K53, K77 and Original crossover left alone inside. The K28 woofers directly connected to Binding post which is fed by the bass Section of New Crossover. I had originally just placed the new mid and Tweeter Horns on top the cabinet since the Motorboard of H1.5 is not compatible. I liked the sound stage with the raised Mid and Tweeter so I decided to make a top section cabinet. Quote Link to comment Share on other sites More sharing options...
Pondoro Posted July 8, 2021 Share Posted July 8, 2021 So the old mid and tweeters are inactive and you raised the mid/tweeter by adding new? This is an interesting mod since most Heresy modifications attack improved bass. Quote Link to comment Share on other sites More sharing options...
radiogram Posted July 8, 2021 Author Share Posted July 8, 2021 The Bass improvement with K28 over K22 is significant. There is more mid bass warmth and more fullness. Overall I find these awesome. I have had so many "so called" auidiophile speakers but none let me enjoy music like these even when I am in next room. I like this even more than my Cornscala I built 12 years ago.

radiogram Posted July 8, 2021 Author Share Posted July 8, 2021 Independent of Bass, I find the refinement in upper mids to Treble and extension alone is worth the upgrade from H1.5. Quote Link to comment Share on other sites More sharing options...
