I will go out on a limb and say the Wilson Maxx ll.
The series 2 upgrade on these speakers is truly amazing as it has much of the X-2 technology at 1/3 of the price. They are a speaker worth owning--so much so that Wilson Audio has discontinued their much more expensive X-1 Grand Slamm Series lll as it is outperformed by the Maxx ll
