Sounds great !!” (J.D.) another customer........"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."J.M. another customer........“What an amazing difference the crossovers make. The mids and highs actually sound transparent. Thank you”D.W another customer........“excellent,item as described great packing,improved sound detail,impressed!”(W.E.) another customer........"Fantastic crossovers, they make my JBL100's sing. Thank you." 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." another customer........"Does nice work! Great upgrade to JBL L100" another customer........"Very very good result."F.P. another customer........"Installed them today......they sound spectacular" another customer........"Stellar JBL L100 crossovers! beautiful workmanship" another customer........ "My feedback is definitely positive. My good old JBL L100s are singing perfectly" another customer........"WOW! These are amazing. Among a long list of things that are wonderful the soundstage is absolutely phenomenal. Thank you."(D.N.) another customer........ "I love the work you did. They sound great, thanks. (A.N.)
