I have never had a hemp-cone speaker before so I don't know if my experience is typical. This speaker took a long time to break in for an 8", about 20 hours, but it sounds fantastic when done. The difference between NEW sound and broken in sound is bigger than paper cones. Very organic, wide sound. It does sound like a bigger speaker.
