I wanted to thank you for posting the link below that displays a graph of the frequency response of CD horns.
This is a great illustration and helped me to calculate the needed Passive EQ filter with the help of DJK.
I also used the Jeff Bagby Excel program (version 2.0) which shows a great graph of notch filter response compared to original driver response.
After adding the parallel EQ circuit of 8uf, 1.2mH, and 20 ohms, the system has an all together new sound. I kept the current 3-way configuration. I will do some measurements over the next week to double check what I think I am hearing but the big hump which starts at 800Hz, where the mid band pass crossover section begins, going to around 10kHz seems to have been greatly reduced. I like the sound of the system much better now.
Thanks for your invaluable advice.
Have a great week.
