I'm still using JBL L212s I bought in '79. But I built new crossovers, Couple-Charged, the same type of crossovers used in JBL's top of the line Everest and K2 models. That design keeps the caps operating in class A mode. Also added spikes to the bases, which didn't exist back then.
But I also have the latest generation of the L212, the Performance Series PT800s, that I use in the HT, and expect to use them for many years also.
