I've got a pair of RAM CD 20's. The drivers are supposedly improved versions of those on the RAM 100's, but they're round as opposed the shaped ones on your speakers. If mine are of any interest to you, let me know. The corner of one cabinet has been bashed in and the reflex ports ( which look suspiciously like toilet roll tubes painted black!) have become detached, but as far as I remember, they work fine, no surround rot etc. In case you haven't found it, look at the Falcon Acoustics website for a section on RAM speakers. Good luck!
