After checking into the a/d/s/ subs a little farther, it has two major strikes against it. For ultimate SQ, an underhung VC is essential, the a/d/s/ uses an overhung. For SPL, a large xmax is necessary, which the a/d/s/ doesn't have. One very nice design feature is the high sensitivity for a 10. It will only take 1/3 the wattage to reach the same volume levels as a JL10W6.
