Welcome to the army of the "Great White Horn". I have been using these beasts for almost thrity years.
The flange on these horns is designed for use with a 1.4" or 1.5" driver. The JBL 2420 is a 1" 3 bolt "JBL pattern" driver.
Adapters are available from Electro-Voice (ADH-1) that allow a 1" "thread on" driver to be used with these horns. The driver to use with these adapters would be the JBL 2425 or JBL 2426 with the 1" "thread on" connector.
I am an active crossover type of person -- I like 24 dB / octave slopes. That being said, on the bottom end anything between 700Hz to 1 KHz works well with these horns and the drivers I listed. The actual crossover point will be predicated by the upper response limit of you woofer and its enclosure. On the high end, I've always used a crossover point of 10 KHz to a JBL 2404 "baby cheek" tweeter.
Hope this helps.Rerurn to Romy the Cat's Site
