I'm comparing two versions of Fane Crescendos with Pulsonic cones from 1973; the 12" version and the 15" version. David Gilmour used the 12" version in his WEM Starfinder cabs. The purpose of this video is to determine if you get close to that tone also with the 15" version. I'm playing the speakers with a 1981 Hiwatt DR103 and a 1973 Fender Stratocaster and a 2008 Gibson Les Paul R9.
