If it was me, I would put an extra set of connectors on the show speakers, and promotional pictures. Just for show.
Imagine these two situations:
1) Rich football player (Peyton) enters the room in the market for speakers. Likes the speakers, looks them over and sees that they are connected by unusual connectors. Thinks to himself "those connectors won't work with my $10,000 spaded cables". He then leaves the room, goes to the next room and buys a pair of B&W speakers.
2)Peyton enters the room, likes the speakers, looks them over and sees that they are connected by unusual connectors. But also sees normal connectors. Asks Danny about it, and discovers the unique flexibility of the speaker, as well as the advantages of the tube connectors. Thinks to himself, " two connectors who is the genius who thought of that 'Jack's extra Jacks' idea?" (milehighguy). Buys the speakers.
