All you need to know is the sensitivity of the speakers in
question, and the type of cabinet (open-back or closed-back),
and you can compare at will. Celestions (at 100d–(at)–W/1M, as a
hypothetical example) with a 30W amp will be about the same as
EVM12Ls (assume 103d–(at)–W/1M) in a 15W amp, as the 3dB difference
in speaker efficiency is equivalent to a doubling of power. You
can play a loud rock gig with a Deluxe Reverb, if you have a
really efficient speaker, like a Kendrick or EV. Conversely,
you can crank a Pro with the Utah-brand Fender speakers and
not be as loud as that same Deluxe….. Food for thought….
