Hi, I've got a Blues Jr with BillM's mods. 30 watts. It's a beauty. It's a NOS with the original Jensen C12k in there. I'm into the sound and letting it break in. But I'm wondering about the two speakers mentioned in my title. I'm wondering how they maintain their edge. I like bright speakers when they break in because they cut through nicely. Does anyone have a longtime friend in the Cannabis Rex or Texas Heat that can tell me about that aspect...? Thanks.
