I'm buiding this now, but can't find any follow up on this one, although due to the Author "I THINK" I trust this will work properly, I can spend my cash only once

Yes, I'm making some right now I have pics if you need schematics or where to get parts I'm here to help.

What 2"driver you gonna use?

[earspoiledbyjbl]

I'm using JBL2426J driver with the butt cheek horn.

The boxes were made by me and the parts are; JBL2205H, JBL2123H, JBL2426J, JBL2405H and the new charged coupled x-over N3145 and I'm using a regulated power supply with 16vdc instead of a battery.

Ah well, well it was me to do about the 2"driver part, so wanted to know if that modification was working as intended.
Nice project btw, did you do any compensation for the 2344 horn in the filter? I tried that combo too with the 4355 filter by 4313B, it was clear that that filter wasn't ment for a Bi Radial horn although it sounded nice. Btw I used the P Audio version with a 2445, so there was a LITTLE mismatch between the driver and the horn at the throat entry

yes I used a fixed L-pad and a zobel network to keep a flatter response in the middle of 1250kHz to 9500kHz as well as keeping the impedance down for the amp. I used a 12oct slope @ 1250kHz and 18oct slope @ 9500kHz.

[Hans Bleeker]

Knowing what an unfinished/uncompensated version does, YOu must be very happy with that setup.
Someday ill catch up
My curent try out setup

Well my dad and me worked on them for a whole summer as well as making his 4350 and 4355. It takes a lot of time and money witch my dad help me with cause I was going to college at the time for a deg in electronics so he did most of the wood work and I did the X-overs on them all. I'm sure you will get what you want. For me its the hobby that keeps me going.
