Using all the same amps in a multi-way DSP active setup (with subs) seems unusual. It's like having a set of screw drivers that are all the same.
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.
