Of the initial list, the Xcon does not belong in it at all. You need to take a moment figure out what your goals are, then come back with them and we can all work on finding the best route to take. I really want people to stop trying to compare the Xcon and the BTL. The BTL is an all out, insanely high output driver that is built to withstand some unreal abuse, it is one of the premier SPL/ground pounder drivers made. The Xcon is built to take serious abuse too, but does not have the cooling or thermal capacity of the BTL. The Xcon is meant to take the "SQ" driver to the limits with higher then average power handling and major xmax.
