I'm really tempted to venture into the realm of the "Super 12s" but should I be concerned about the longevity of the drivers? Does the high excursion make them more fragile or decrease life in any appreciable way? I also have a related question (I should probably start a new thread but anyway...): Do any commercial manufacturers make anything comparable to super 12s? Are genz benz or other good quality major manufacturers producing anything that can come close to a Baer, Barefaced, Thunderchild, etc? I've heard great things about the Aguilar stuff, but is it unreasonable to expect the kind of output of a "super 12" from their (or other major manufacturer's) 112s?
