Is that Seas coaxial driver far behind the excel drivers? I do like the idea of coaxial drivers and had been thinking lately of trying that driver married to a pair of 8 inch or a single 10 inch bass driver as a 3 way active system with DEQX. I just wonder though whether the benefits of coaxially mounted "medium" quality drivers outweighs "better" quality drivers separated vertically. Just thinking out loud.
