I have new 2234/35 cones in the 2224H baskets making them into 2234H's. I bought some lead aquarium plant weights to load them up, but broke down and bought genuine JBL OEM mass rings for a mere $85 each. They appear to be zinc (pot metal) so I an be comforted I won't get lead poisoning listening to the speakers. Just have to glue the mass rings in and the dust caps on to make the drivers 2235H's.
The Eminence ASD1001 was my low budget plan for a mid, but I saw 2450J's were actually relatively cheap, so I now have the most modern neodymium magnet version of the 4" diaphragm tweeter JBL makes. The massive ferrite magnet versions cost twice as much.
In this far, I figured I might as well spring for a pair of 2405H's instead of the Beyma clones I already bought. Thanks to e-bay for refunding the first FUBAR pair of 2405H's, I found a second really nice pair.
I wound up air core inductors to make an N7000 dividing network (mid to tweeter x-over) and have the rest...
