The Xcon and Icon don't really directly compare to each other as they are different in design, but both are over hung topology. The new Icon is more of the great all-a-rounder sub. Not an all things to all people, as that is impossible, but it can satisfy the picky SQ guys and play controlled at lower levels in sealed enclosures. On the other hand, it has greatly increased cooling and a bump in motor strength for those people who want to really lean into it power wise and occasionally make things blurry. The Xcon is a different beast, really an elite driver. Meant for the sound quality crowd that loves some headroom, but does not need bonkers power either. A higher Xmax option to many other drivers out there. A little more old style in enclosure preference, in regards to a larger box and lower tuning. But it has been used by the SPL competitors with better results then we had expected.
