Greetings all!
I recently picked up a good pair of JBL 4311Bs in excellent condition. I remember this model well from working in studios in the 1980s.
Since purchasing them I have - of course! - been on-line to read up everything I can about these magnificent beasts! I was surprised to learn of the crossover design - woofer wide open and only two caps.
I've also read the thread here, and on other web pages, about improved crossover designs to smooth out the frequency response, especially the peak in the high-mids.
I love the sound of my JBLs and would never go this far (I appreciate the school of thought that says that one should just leave the 4311's alone to be what they are), but I wonder if something as simple as a low-pass cap across the midrange driver might go some ways towards taming that peak?
(As this "solution" has never been mooted (to the best of my knowledge) you can perhaps infer from my question that my crossover design skills are zero!)
