LE14H-1 is the first one with a black cone. LE14H actually uses the EXACT same cone kit, as LE14A. The LE14H-1 has a black cone, and a longer voice coil winding. It also rolls off at a slightly lower frequency (doesn't go as far into the midrange frequencies), compared to the LE14H and LE14A.
LE14H-1 can be found in the Ti series speakers... 240Ti and 250Ti, as well as the L250. They're also used in the Fosgate Audionics FS400 subwoofers... but I doubt you'll find a pair of THOSE anywhere.
The LE14H can be reconed as LE14H-1. Just requires the proper recone kit. I've generated those from aftermarket parts, when needed (and which, BTW, met factory specs afterward- I tested to make sure)... factory kits are hard to find, sometimes...
