Which actually, does virtually nothing for the owner of the sub.
Should you ever require a recone, all the "Quick Change Assembly" feature is going to do is make the life of the person reconing it -- generally, somebody from an Eclipse repair facility or perhaps even a dealer -- a whole lot easier.
Unless you work at an aforementioned facility, the required parts are going to be very hard, if not impossible to come by. Cost wise, it's going to be the same if not more than a regular recone for your standard Joe-Schmoe SQL sub (XXX, W7, Brahma, IDMAX, Flatline, TDX, etc.) -- most likely a little more since it costs more to manufacture an assembly as opposed to a single part (basket, cone, motor, etc.)
Two thumbs up to Eclipse for good marketing skills -- who cares if the buyer doesn't benefit? //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif
