Hi, I'm looking for speaker suggestions for a Blackstar Stage 60 2 x 12 combo amp. It has celestion 70/80's in it currently. I'd like some with better highs, mids that cut through the mix, and a little more bass. I play mostly classic rock/modern rock, like AC/DC, Judas Priest, Joan Jett, but also stuff like Buckcherry, Theory of a Deadman, and Disturbed.
