I never use their automated ordering process. I think a few others have tried and gotten the same outrageous shipping amounts. Just email them with your order and your shipping address. They should respond with a quote in a day or two.

Hi all, and many thanks for your great job in this forum.
regarding this post

external crossover should really have a 18db/oct slope? sometimes I've found sometimes a 12db/oct value .....
thanks,

Been in hospital for the last 3 months looking forward to get back to this project when I'm able !
I am finishing up my 3155 cc networks \ I have 2 questions \ 1 hooking up the Lpads does the terminal 3 go to crossover and terminal 2 go to the driver and terminal 1 go ground / as in the 4344 MK ll networks ? question 2 - is the EQ for the 2202-2441-2405 used [ N4 N5 N6 K4 K5 K6 } if so is it both the K and N - and what would the value be ? the 2202 is replaced with the 2123H as what 4313B did .... thanks for any help
Yes.
Those are just labels. They mean nothing. EQ was my notation for "Equivalent". N4, N5, N6 are nodes for voltage drives in LEAP.
Everything in that schematic including and to the right of S6 and S8 is nothing to concern yourself with. Just replace all that stuff with normal L-Pads. It looks like the L-Pad on the 2441 is supposed to be 16 ohms and the L-Pad on the 2405 is supposed to be 8 ohms.
Thanks for your time to answer my questions , hopefully i will get these done , I had one of the worst years of my life !!! once again Thanks !!!
Im guessing + to black for 2123 2241 2404 ?
i give . please what is the answer
I Googled 'JBL 3145', went to their website and it looks like they did just that on the top three transducers.

Old thread but might help people building these nowdays, I have build both networks, the one with and the one without coils, The one without did every thing perfect except that it has some harsness in the vocal range ön the 2" driver if you have a huge choir . On the other hand the non coiled version seems a litle bit more dynamic and open to me. So I personaly feel, for slam take the non coil'd and for accuracy the coiled.
Yes Hans, it's still very helpful. A thread may be old but as long as there are people using big vintage 43's any info is appreciated
I bought a pair of 2123H (Sorry, no more stock looking 4343 ) which I hope to receive at the end of this week and thus with the 2123H and 2441's I won't be able to use Giskard's 4344MkII networks but instead I need the 4355 ones.
What kind of "2 did you use, the 2446 with Ti dia's?
2445 with Aquaplas , 2446 somehow doesn't fit in, I cant explain why but 2445 is way better sounding in this combination. Doesnt matter what membames I use btw, Ribd Flat or Aqua, aways the same difference.
Hi Hans Bleeker,
You said "coils", are there "Zobel impedance compensating coils" or something else?
Can you show the networks schematics?
Do you use 2311/2308 horn-lenses combo, or some others?...
As I have remembered 2445 driver with some other horns, not 2311 can produce narrow, but deep notch around 10kHz.

while 2450 (I think very very similar to 2446) has not such behavior

I ment the inductors as you can see in one of the schematics in this post, 4313 made that network without the replacement inductors for the tapped transformer, I use the drivers as in these schematics as in this post, so with a 2405 on top from 10Khz.
Its not the frequentie response, it has to do with soundstage, the soundstage is what ever horn I use , deeper and more coherent with the 2445 then with the 2446, its a small difference but noticable. Sinds the 46 has a different phase plug I'm not even that amazed about that happening.
Although the 2446 is more cleaner , so im now in the position where I change every week between them because I cant choose
