+1 russ - With passive crossovers, it's much easier to protect the drivers too. I don't use any components between the drivers and the amplifier outputs, just wire. Somewhat risky for the drivers, but worth the risk for the sound improvement to me.
Active vs passive crossover
I think most of forumers in this plaftorm know what are active/passive crossover (essentially crossover before/after the amplification) and understand the pros and cons of them. Some if not all might even agree the best sound reproduction solution is active crossover with DSP. But, my question is, why the vast majority of companies in this industry still chooses the passive route.
