Not necessarily:

Fs = [(1/Pi)/2]*{[1000/(Mms*Cms)]^0.5}

where:

Mms is in grams and Cms is in m/N

>To say light cones are better or heavy cones are better is like saying stiffer springs are better for a car. It depends on what size car they go in, and what type of ride is desired. That's my opinion.

Yep, it all depends on the desired BW and acoustic power/watt you want. If I only need it to load 30-100 Hz, why force a 40 Hz Fs driver with a 400 Hz HF mass corner to do it?
