Great to here there is now another m with a pair of Hartsfields!
My crossover is extremely simple. I have attached a drawing of the schematic.

I use a 16ohm L-pad for the midrange...
Please check out my Hartsfield build here http://www.audioheritage.org/vbulletin/showthread.php?34758-My-Hartsfield-DIY-Project
I use very simple first order crossovers with L-pads that work...
Thank you everyone for your comments!
As for my electronic components:

Hi everyone,
So I have been running this pair of 1959 spec JBL Hartsfields in Dallas for about two months now and I thought it was about time to write my opinion of these.
It took some...
Can anyone here advise for/against lining acoustic foam on the inside of the woofer coffin cover for a pair of 1959 replica JBL Hartsfields?
Thanks
We were thinking along the lines of $12,000 Per pair for the unloaded cabinets. If we could get more going simultaneously, the price per pair would go down due to the increased efficiency of side by...
So basically what I have found is that the LX5 is an "Ok" crossover.
It has some peaks and dips in the frequency response that with some trial and error can be improved. However, when using two...
Final LF Response:
62168
Final HF Response:
62169
Here I varied the HF model impedance of the series resistor and inductor combination to see how well this match the DATS system:
(as you can see it is a very good HF model)
62163
For...
Interestingly enough I am currently working on modeling the LX5 and N7000 for my home built Hartsfield.
With some simple simulations I have found that we can do much better on the crossover...
Hi everyone,
I am working on rebuilding a pair of LX5 crossovers for my DIY Hartsfield. I wanted to start with the stock LX5 and N7000 for E145, 2441, and 075 driver arrangement and then make...
Yes these will get a good home!
I am in the process of moving so they are stored until I have the setup ready for them.
As others have mentioned, the quality of the build and the materials...

Hi everyone,
It has been a while since I posted on this project and I have had some very positive feedback from members.
The horns have since been completed and I felt it was time to follow up...
Hi everyone,
So unfortunately I purchased a pair of E145's a while back for a Hartsfield replica that needed to be re-coned. Both had voice coil rub issues and were making noise during operation. ...
Oh really? how do they get access to the voice coil to get it re-glued? Would it be a good permeant fix?
Hi Everyone,
Unfortunately I have an E145 with a mint OEM JBL cone in it that has a lose voice coil and voice coil rub.
I am wondering if anyone has had thier E145 re-coned or done it themselves...
Sorry there was in error in the schematic but the plot is correct.
R3 = 8ohm
L3 = .364mH
C3= 1.42uf
Hi Everyone,
I wanted to share my progress with redesigning crossovers for my DIY JBL Hartsfield project to document and help others with crossovers as well as a sanity check for my own sake....
Hi Everyone,
I am working on modifying/rebuilding some old JBL Crssovers. My goal is to better match the crossover and my specific driver choice.
(This is for a DIY Hartsfield stereo pair).
...
The Hartsfields are not for the faint of heart!:)
The wood work and geometry involved to do it right is mind bogging!
Any chance that you would be willing to sell your pair of E145's?

Hi Everyone,
I have asked this question once before without great response so I figured I would ask again...
I am now at the point where I am finishing up my stereo Hartsfield pair and am again...
