Alternative to tapped inductor in 3110a or 3115a?
Greetings,
I have a multitude of 2225H, 2445J (with 2380 horns), and 2404H drivers that I am trying to put to use. I would like to build something similar to a 4673 clone but the tapped inductor of the 3110a and 3115a crossovers have me stumped. Is there any way around them using multiple standard inductors?
I have seen the 3110 equivalent HP filter that gets around the tapped inductor, but I need the "a" version to go with the CD 2380 horns.
I have used the Behringer CX4300 in the past but I want to keep this a passive crossover.
My next question is how much of an issue is CD compensation if the 2404Hs are blended in at 5kHz?
Thanks for any input.

Crossover Network Rotary Switch
Well, without having an actual JBL network on hand to do an exact comparison. This is my best guess as to the correct switch for the network. I am pretty sure that JBL is using an Electroswitch brand rotary switch. But, without actual physical measurements I am not sure which Electroswitch switch series is being used. (“C4”, “D4”, or “D7”) Electrically, any of these 3 series should work and could be interchangeable. Now, there are some key words that must be followed when ordering this switch. The switch should have “Solder Lug Terminals”, “1 deck”, “2 poles per deck”, and “3 or more positions” and “Non-Shorting”. And have adjustable rotation stops. So, if the switch has more then 3 position, you can reposition some stops to limit the shafts rotation to just the required 3 positions.
Actually, for the 3110A network a “1 poles per deck” switch would work.
While a N1200 network would require “2 poles per deck”
Considering cost and availability, I would have to say that the “Electroswitch D4G0205N” switch would be my best guess and it should work for this application.
