I have several JBL E-140 15" drivers for sale.
They are highly efficient, and suitable for bass reflex enclosures, mid-bass horns, and subs. They are rated at 400W.
These were removed from concert sound enclosures. Some still have original cones, others have been reconed, but all have JBL factory made cone kits.
They are in good used condition.
I can be reached at (704) 779-1910 or via Asylum Email.
