I have a C.Rex in my DRRI Combo, but would like to add an extension cab to give it a bigger and more dimensional sound. Which speaker would you recommend pairing with the C.Rex? I'm specifically looking for something that will make the cleans be more dimensional, possibly something that tames the brightness and flabbiness a touch. For reference, I played a SRRI the other day that I really loved. I know I can't get to that sound, but could an extension cabinet and speaker get me closer? Which speaker do you recommend?
