I was sitting around thinking to myself while working on my active 3-way design "Self, why is it that virtually no speaker manufacturers offer an active crossed loudspeaker even though it is superior to passive crossovers?". I haven't found an answer to that one, but it did get me thinking about the idea of buying nice pre-built speakers and replacing the passive crossovers with something like a Behringer DCX2496. I personally am going to use a PC with KXProject drivers as my active crossover, but I was wondering if anyone had any experience replacing existing passive crossovers with active ones in pre-built speakers. Specific examples and explaination of the results (and even pictures!) would really be appreciated.
