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.

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

Some Voltage Drives ;



Pic with Lpads in place ( showing impedance stabilizing coils ) ;

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.

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 ?

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 !!!

just would like to check - what would the the polarity connections be for the drivers / 2123H 2441 2405 / and biamped 2245

Im guessing + to black for 2123 2241 2404 ?

[kartsmart]

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.
