I've had excellent experiences with Star Sound's Audio Points on my custom racking systems. In fact, not too long ago, I became a dealer for them.
You might also try experimenting with ics for your sub. All ics generate time smear to either a very small or great degree which leads to ill-defined and sloppy bass (and other things for main speakers). My limited experience tells me the vast majority of scs and ics generate great degrees of time smear and you'll never know it until you try one with less time smear.
Audience (AU24, Maestro, and Conductor series) or Audio Tekne are two names that come to mind that generate an absolute min. amount of time smear. Speltz Anit-ICs is another.
Properly addressing vibration mgmt techniques along with installing good quality ics can make the sloppiest of subs sound extremely tight, deep, fast, and well-defined. Which is what true bass is supposed to sound like.
-IMO
