3 Way Seven Pi crossover, with JBL CS3115 Parts

Hi Wayne,

Thanks for all you're help. The crossover diagrams you make are easy to follow. Designing the crossover and "really" understanding it, is something I have difficulty with.

When you get a free moment (I know your very busy) If you could help me with a crossover, I would greatly appreciate it.
Here are the drivers I wish to build into a seven Pi.
All specs are from JBL.

Low frequency;
2226G 4 Ohms sensitivity 89db spl 1/1

Mid frequency;
M209-8 8 Ohms sensitivity 105db spl 1/1 (with horn)
Fs 91hz Re 4.9 Le .265mH Qts 0.385 Qms 2.04 Qes 0.475

High frequency;
2425HS 8 Ohms sensitivity 111db spl 1/1 (with horn)

JBL has recommended in their tuning specs to cross these parts at 420hz, 1.6khz
Attenuating with
+2db woofer
-5db mid
-10db Tweeter
I dont know that this would be the same in a Seven Pi corner horn, but It might be helpful information.

I think this will make a great Seven Pi corner horn.

Thanks,

Bill
