Ever Bought an Audio Product that was Stupid Good for the Money?

I have two similar pairs of JBLS 1959s (my fathers) and 1964 bought in mint cond for $400 one is the 15 inch Mid Woofer the 64s have the 12 inch (D131). I want to upgrade the crossovers who did the work and what do you think did the most good.The sensitivity easily equals my Klipsch Heresys and approaches my Las Scalas (Yes I own a lot of speakers) I also have cheap but Gold series Tannoys, VSA VR2s and Focal Electras etc. . You can drive the Klipsch with a fraction of a watt but be aware that a lot of that volume comes from those powerful squawkers. You’ll want more power to drive the woofer to the same levels -really. Your new crossovers may take care of that

Mine have the D130 (15") woofer with the bullet tweeter and N2400 x-overs.
I did the work myself. Found a crossover diagram online with the parts values. Parts express has all you need. You could also use mundorf or other exotic parts if desired. I replaced the tweeter level controls with new ones too. It's needed! Modern parts are smaller and fit well in the boxes. I was able to remove the original parts and wiring without any cutting and save them. Not a difficult job.

A pair of 6l6g tubes made by rca with a tungsol label from the 1940s. They we're only $86 and they had a HUGE impact on my system.
