One way o another, speakers (including OHMs) must be mated with amps that are well suited to diving them optimally. Optimally often infers the best case for achieving a generally (if not exactly) flat response. Same true with OHMs.
Active speaker designs see to be one way and perhaps the easiest to accomplish this. The designer does the integration for you. That's a great and perhaps the easiest approach in general for many I think, but certainly not the only way. Matching amp and speaker yourself certainly provides more flexibility and variety in end results, so it may take a while for someone to stumble (or objectively determine) what the right match is. The right match for an individual may not be the same as intended by the speaker designer, although one would expect the designer to be the most qualified to make the determination of how to meet their sound goals technically by integrating amp and speaker..
