[QUOTE="handsome, post: 1070072, member: 772"] x-over type depends on your design. "Ideal" x-over is a 4th-order Linkwitz-Riley alignment. That is the only configuration that "sums flat" IOW if you add the response of the two crossed-over drivers together you will get a flat frequency response. Other x-over configurations give you dips or bumps when summed. This assumes that both halves of the x-over share the same x-over frequency. Any order crossover will give you a phase shift - that's just physics. A filter's (ultimate) phase shift is 90 degrees per order. [/QUOTE]
