Another detail sometimes overlooked is the crossover. Active biamped speakers have active crossovers at line level, which are way more precise than a passive crossover at the speaker side. You'll see a woofer or tweeter inside a bi-amplified active speaker is connected directly to the amplifier without any passive crossover.
I fix powered speakers all the time, and usually the more expensive studio monitors sound very very good indeed... I'd say it's hard to beat them... Not a tiny budget speaker, but a high quality 2 ways monitor is defintely a very good speaker. On the other hand, I think they won't last 40, 50 or 60 years as many solid state amps and passive speakers still working today.
NO AFFILIATION, but this is a €100K powered speaker: https://www.bang-olufsen.com/es/es/altavoces/beolab-90
Would be nice if they actually showed the driver's in those B&O cabinets, as opposed to several photos of basically the same thing
