I have a Fender Red Knob Super 210. Love it. But the speakers are starting to crackle so time to replace. Was wondering if anyone has done this. Thinking of either Eminence or Celestion. So many to chose from. I play a Les Paul (blues) and a 7 String for hard rock/metal. Want something to handle the low's and still have something left for the "softer" stuff in the set. Suggestion are welcomed. Thanks in advance.
