I just picked up a cab with 2 x 15" Fane speakers for next to nothing. I have no knowledge except I have heard of Fane guitar speakers from guit4rists before. The label is blue and says Heavey Duty High power Loudspeaker and few other generic comments. There is a number on it. 15108. Any info appreciated.
I bought what sounds like identical speakers a few years ago off ebay UK, I paid around £30. IIRC theye were from some industrial PA speakers, kinda lie a tannoy, they were 150 watts each & had a secondary cone in the middle around the coil cover.
I had them in a Marshall JCM 800 & just like Scott says my Hiwatt 201 made very short work of them, switched them out a few weeks later for Emminenece Deltas.
