Thank you 4313B for the time spent on this project!
First off I would like to point out that the 350hz Edgarhorns are mine and are the ones in my avatar. :D
I had tried some EV DH1A compression drivers on them in the past. Dan (Cosmos) also heard them when he visited me before. We both agreed the HF extension was decent enough(passive crossover @ 800hz using passive attenuation/EQ), but the "simbilance" or what I call the "titanium sound" was readily evident.:banghead:
I plan to use a 4-Pi (Wayne Parham) 1.6khz crossover w/JBL 2226J's on the bottom end w/JBL 2446 compression driver equipped with Be diaphrams as soon as I can afford to make that happen!:)
I see with the 2446/Be/Edgarhorn plots that the 1.6 khz region looks to be fairly flat response wise. I don't know enough to extrapolate all the info here so I'm actually speculating!:blink:
Thanks a million for the help 4313B!!!:applaud::applaud::applaud:
Regards, Ron
PS: Did my e-mail with the att/EQ chart help show what Wayne is trying to do with his crossovers?
Here's some quick values to try out for 16 ohm diaphrams
Using my chart on the e-mail I sent out:
R2 20 ohms
R1 60 ohms
C1 .2 ufd
This is for approx 15 db attenuation/EQ on a 1.6 khz crossover which is the closest I can find for the difference between the JBL 2226 @ 97.4 db/watt and the JBL 2446 @ 112 db/watt if I have the information correct.
The crossover I plan to use is the one I sent you the schematic of. I adjusted the values to reflect the 16 ohm LF and HF drivers I'm using (ie: 2 x coil/resistor values and .5 x cap values).
My application is for passive crossover vs the active bi-amping that Rick, Brad and Dan are going to use.
Thanks again 4313B!
