Perrew,
Just to be clear, box size isn't the key here nor is driver size. The type of box and its size relative to certain mechanical characteristics of the driver determine how highly damped the subwoofer system will be. For instance, a 10" woofer cone mounted in a 13" sealed box is quite probably (but not with absolutely certainty) more highly damped than the exact same driver in an 11" ported box. Choosing a smaller box or smaller cone isn't a reliable solution. OTOH, choosing a sealed box is probably (again, not definitely) a good idea if you want a highly damped subwoofer.
I believe that all the JL subs are sealed designs and those I've heard certainly sounded like highly damped designs to me at audition. Therefore all of them, including the 13" model sounded "fast" by my definition.
You might hear it differently.
