"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."

 "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."
