Paradigm signature vs. Sunfire signature

General feedback of which one to use (why): paradigm signature Servo Speakers vs. Sunfire Subwoofer EQ signature

It seems a bit cheesy to compare Paradigm's 15" sub against Carvers 10".

The only fair comparison would be with Carvers Top of the line 12" Signiture model.

One can only speculate why this apparent subwoofer shootout chose Carvers smaller cheaper and less capable model to make their comparisons?
