I like the look of them. A little googling found this from someone who'd just bought a used pair (though it was from 2006).
"For those of you who don't know them, they date from the early 1990's and sold for about £1000 when new. They are an unusual design that has a 6.5" woofer and a tweeter on a baffle plate on the front, and a further 6.5" woofer on another baffle plate on the back, which is out of phase with the front one and connected by a metal rod, through to the front unit. These baffle plates are fixed to a central pair of thick metal columns that go straight down to the floor and the cabinet is "hung" over this, with no direct connection to the drivers. Unusual looking, and when have you seen another speaker that has a grille on the back as well as on the front??!!
This pair have non-original tweeters but the seller supplied me with an unused set of correct new ones, plus some new baffle plates and full instructions, brochures and disassembly details, all for £31!!"
If you're only gong to get that much for such a decent pair of speakers, I agree with Matthewpiano, keep them, and enjoy them.
