Does anybody have any thoughts on these speakers? I replaced an old problematic JBL in my Twin with one a couple of years ago, and loved it. I recently got a pair of alnico's and a pair of ceramics for my Hard Truckers cabs and I'm not very impressed, especially with the low end response. I got a pair of old JBL D120's back from a friend, and installed them in one of the HT cabs. It was like comparing a Porsche to a Honda. Very different from the California in my Twin. I played them through my Two Rock Classic Reverb, and my CT45 and got the same disappointing results, while the JBL's killed me with tone!.
