This auction is for 1 (each) cross-over upgrade service for JBL brand speakers. Model L100A.
If you want a matched pair, please visit my ebay store and find the pair auction.

This particular model uses resistors to lock in the mid and tweeter to the zero (flat) level and bypass the front Lpad controls. It is the best performing type of crossover as the Lpads can be problematic and introduce lots of distrotion.
Comes with full length wires to reach the drivers and input posts.

The auction includes a pair L100A crossovers using Nedlab 1% high fidelity audio capacitors.


You will get an entirely new crossover with high grade components.

*New crossovers to original schematic with some small improvements, including Nedlab 1% film high fidelity audio capacitors.
*Film non inductive resistors in the tweeter section
*OFC 99.99% pure copper wires.
*Point to point wiring with tin/silver solder


Fully tested on lab analyzer comes with frequency response test sheets with better tolerance than +/- 1db


Available also many other JBL models, just email with request.

Price is for pair crossover upgrade.

For repairs, email me with your problems and I will quote fix cost.

20+ years of experience in hi fidelity crossover design.

"I put the crossovers in and I am stunned. I have had the L150's since I purchased them new in 1980. They started irritating me awhile back. So I got these new crossovers. Wow. Again, wow. They sound like a new speaker. Well worth it."

another customer........

 "After several hours of listening to various LP's on my "retro system" Thorens TD124 w SME 2009 and Shure V15IV through my Pioneer A27, I concluded that the L100s had been transformed into JBL 4311 studio monitors ! The sound stage seemed wider and the sound was clear and clean throughout the frequency ranges. With the old crossovers I was getting a muddy mid range and boomy bass. Now the mid range in particular was much cleaner and and more detailed. Your crossover upgrade has been the best speaker investment I've ever made."
