Reading the Outlaw site, the claim is that the dual crossovers allow for "optimal performance" in either a vertical or horizontal position. If that's supposed to mean that the performance when horizontal is just as good as when vertical, that's highly unlikely. While horizontal configurations do require different crossover adjustments to minimize their problems, this doesn't make things even; crossover changes can't do everything. It's highly likely that while horizontal performance is significantly improved with the new crossover, the performance while vertical using the vertically optimized crossover is still superior.
