To take a slight left turn on the original topic - I recently acquired a pair of 5" Watkins woofers as spares for my Infinitesimal 0.2's and they have have black poly cones. The part number stamped on the magnet is 902-0470 which, according to the spec sheet on the Infinity Classics site, is the replacement driver for the NLA originals. I've never seen a representation of any Infinitesimal 0.1, 0.2, or 0.3 DVC woofer with other than either grey or clear poly cones and was wondering if anybody knew if Infinity used black poly on some of the later replacement drivers that they sold separately.
5" Watkins? Is that the mid bass in Q series? Made by watkins?
