Hi Guys,
I have a line on a K120, but I have no way of telling if it is a recone. Is there anything I should look for? Or is it easy to tell by a marking on the cone? Thanks!

PM me if you want Ive been in this market for about a year now so Im learning on a curve what is real and not. I would say that if you look at the cone on the underside it should have a hand written code on it. Not all speakers have this! the next thing to look for is the dome, is it clear or black or silver? then there is the rim this is BIG I have schematics on all of the JBLs so...
