That rating only tells you how much power they can generally take before damage occurs.
The numbers you are looking for is the sensitivity rating which is decibels of output at 1 watt input. The more sensitive speaker will be the louder one, but sensitivity can vary by frequency even though the published specs rarely offer any detail.
Interesting, thank you.
The Copperback’s sensitivity is listed as 100dB.
The Cannabis Rex is listed as 101.8dB.

According to what I’ve read on Celestion’s website, that's a negligible difference to our ears.

Also the round, seemingly less precise number for the Copperback makes me wonder if it’s really an approximation.
Based on all that I would conclude that both speakers are producing nearly equal volume, with the CRex possibly sounding sightly louder.
Another spec that can be seen on the above pages is Resonant Frequency (Fs). There’s a much bigger variance, with the Copperback at 55Hz and the CRex at 96Hz, but I don’t know how that might effect tone and/or volume, other than to speculate that we might hear more Copperback at lower frequencies, and more CRex at higher frequencies. Although according to some info I gleaned HERE
, the frequency range of a guitar in standard tuning is about 90-1300Hz, so maybe the lower Fs of the Copperback would only be apparent in a drop-tuning or with a bass guitar.
For whatever it’s worth, the frequency range on the Copperback is 70-5500Hz, the CRex is 80-4500Hz.
Regardless, the combo sounds great to me and I’m having a lot of fun with it.
