It could not be that all of the ones I owned were "the good one", but then again the ones I owned were real Jensens, not reissues.
I used to find them in old PA speakers like the ones you find in schools, offices and factories. I usee to get C12Qs from a certain Rickenbacker combo model that I kept finding in SoCal. Those I like in my BFDR. So when it comes to Jensens I prefer finding old good ones versus the reissues. Not easy, I know, but worth the effort. Gotta visit thrift stores, swap meets and ham fests. Meanwhile, you still need something you can live with.
