I have a set of FOUR Samson quick release swivel tower speakers (the same quick release mount exile uses) that are loaded with Focal top of the line PS 651v1 component speakers. The clamps are for a 1 7/8" tower. Will sell for $800 shipped to the lower 48 states. Sorry, no international shipping.

These would be fantastic for surf speakers. The focal components are some of the clearest best sounding speakers on the market.
