Knowing his designs the be tweeters are not the issue as much as the Xover itself which
the parts are at best average ,I hav3 helped rebuild several. and when you ask him he says cannot show Xover
Its proprietary , it’s theQuality of the build In question not as much the design
and the cabinet design rings like a 🔔 vibration = distortions , He should at least put black hole or other damping materials ,and or bracing especially on these $$ designs.
