There are indeed quite a few more. Harbeth, however, are unique in that with a government research grant they developed a special polymer (which they call Radial) that was optimed for this application. Others mostly used ordinary polypropylene. There is quite a bit of documentation about this on the Harbeth website.
Harbeth blog
Alan Shaw, the designer and owner of Harbeth, the high end speaker manufacturer, has started a new blog on the Harbeth User Group: http://www.harbeth.co.uk/usergroup/forum/designer-s-blog/75232-ahoy-from-the-engine-room
He discusses audio and particularly speaker design, but also the science of hearing and the methodology for testing and listening to gear. Anyone who is interested in the scientific approach to audio engineering (and sensible purchasing decisions) will enjoy his writings. Subjectivists may be annoyed, and so will be the snake oil sellers.

Sorry, that is what I thought. Anyway, the Harbeth material is a proprietary compound to have just the right mix of properties. See here for some of their explanation: http://www.harbeth.co.uk/usergroup/forum/the-science-of-audio/213-harbeth-radial-v-other-cone-materi... |
