Even with the "provenance" I have to assume that speaker collectors are not the most prolific group, also assuming that "collectors" and "owner/users" are not the same group, this in itself relegates you to a very small segment of "people in the money". However, the "E-Bay" auction can reach a huge population compared to conventional advertizing and local auctions. It would be interesting to hear what the "Keno Brothers" on Antiques Road Show would have to say about the K-horns. Hell, write them a letter and see what happens.
