Hey there -- I just got my first Celestion Alnico Blue 8 ohm 15 W speaker and immediately put it in my '54 Tweed Deluxe. It sounds sooo amazingly good! Now, I see what all the hype is with these speakers. So, my dilemna lies with worrying about blowing this expensive speaker. How do you guys use these? How many watts can they really take? What about if I pair it with another speaker in a 40W Pro Reverb (which I never run past 4)? Will using two mismatched speakers be additive as far as power handling goes? I was thinking of pairing it with either a G12H30 or Greenback or perhaps another Blue but am weary of the power issue...Hmmm.
