I have the same situation as @donavabdear , about 17 speakers in my HT most of which are active. I saved myself piles and piles of cash on speakers cables and external amplifiers PLUS get the benefit of active crossovers. The specs for my Paradigm Reference Active speakers are in my system profile. Each speaker is internally biamped. That is like 34 channels of amplification that I didn’t have to buy and setup separately. In a word, the most efficient use of an audiophiles budget is to save money using active speakers and use the money saved on room treatments, clean power, source components, and interconnects.
Dynaudio makes both types of speakers and they break it down in this article:
