I'm going to turn this into a useful example. Let's say that when you were looking at your Nemesis you were also looking at another cab. Here's the specs for the Nemesis (assuming this is the right model 15, they've been through a few different models):
Power Handling 250 Watts RMS
Freq. Response 38hz - 18khz
Impedance 8Ω
Sensitivity 100dB SPL@1W1M
Weight 42lbs[/quote]Mine's the older one with a slightly different spec, but that's not really relevant

Power Handling 350 Watts RMS
Freq. Response 35hz - 18khz
Impedance 8Ω
Sensitivity 101dB SPL@1W1M
Weights 48lbs
So you might think so yourself, well the latter cab is a bit more powerful, a bit more sensitive and goes a bit lower, so it's worth the extra weight. But let's assume that Vd was also quoted.
For the Nemesis = 350cc
For the Brand X cab = 250cc
This means that despite the Nemesis looking like it'll be less loud and fat according to the original (and very open to marketing abuse) specs, it will actually produce greater low frequency SPL.
Alternatively you could have an excursion limited power handling figure added to the specs (which would be likely to show the Nemesis as having more) or a true low frequency sensitivity figure (ditto). The product of these two figures would show the Nemesis as having better performance.

Aha.
So to use a motoring metaphor, judging a cab purely on things like sensitivity and frequency is a bit like judging a car purely on horsepower and 0-60 time... the first car has more horse and a quicker 0-60, but when you look closely at the second car it has more torque and a better 30-70 time, which in reality is far more useful. Have I got that right?
