I guess I should clarify what it is I'm trying to ask. Hemp is being used for so many applications these days. I just found out the door panels and dashboard in my '07 MBZ are made of hemp. Chosen for its moldability, strength, stiffness and natural damping abilities as well as its inexpensive cost and availability. These drivers are quite stiff, on the 4 ohm taps they seem to mesh better with the Vifa tweeter that's in there (awesome tweeters BTW), much tighter sound than on 8 ohms, but they still seem very directional and inconsistant. I'm contantly adjusting position, using different port plugs and moving my bass traps around, changing amplifiers and sources too. One minute the music sounds terrific (lots of bass, great midbass and stellar highs, the next I don't even recognize it. It could just be me, my new room is probably one of the worst environments to set up a system in, it may be the room too. But my full range single driver mini onkin crossoverless horns sound phenomenal. They use the Merrill driver that I was going to try replacing with a 5.5" hemp driver that Fritz raves about, he gave me these two ways to try out so that I could get a taste of the hemp sound but I'm not sure I like it. As far as I know I have the only Monitor X pair in existance. For Audio Note to be using them, there must be something there. Maybe Fritz is on to something.
