This has frustrated me for a long time. You can always do a better job with active crossovers and matched amplification than with a passive system. Add DSP, and you can do things that few purely mechanical speakers can hope to accomplish. But then, I'm bugged by the elimination of tone controls as well. Sometimes, purism can be self defeating.

Mostly because the effort necessary to surpass top class amps and passive network is much more difficult than paper theory, one such problem is overcoming the microphonics from amplifiers when placed inside enclosures.

It's an engineering effort, to be sure, but pro speaker and subwoofer manufacturers certainly haven't shied away from it. My sense is that it just wouldn't sell in the high-end consumer market. Audiophiles like to choose their own amplifiers and cables and to use the sonic characteristics of one component to balance the sound of another. And there's a certain amount of equipment lust involved as well.
Concur Josh,
there are other reasons why pro speakers fail in fhe high end, frankly just not enough quality of a speaker, much different design criteria .....
Regards
Yeah, the design criteria are very different. I've never heard a monitor I would want to use at home. The one area in which they are superior is dynamics -- so many audiophile systems can't play at realistic levels.
Puesdo audiophile systems Josh ... :)Yes and mainly because most are content with 80-90db for playback levels and at peaks at that. As to active , my experience with active setups date back to early seventies and my first SOTA attempts. Back then 2 and 3 way active was doable and i had used xovers from Sansui,Sony , Crown and custom built discrete units, this worked really well over what i had before , but later , after i had acquired a Pr of MC3500's in 78 i went back to a full passive design and with the better amplification the system was much better. Over the decades i have tried many different itinerations of active setups, but always found the best results, Passive for mid-twt and active bass/mid-bass to be the best compromise over a full active setup.
Active in the bass makes not only good technical, but practical sense and does work in real world application. Connecting the amp directly to the woofer has many benefits, as oppose to running thru non-linear miles of aircore (due to big values) or linear, but compression killing laminate coils, not to mention the phase angles presented to the amplifiers as is usually necessary for a good low bandpass filter.
Still Full passive can be hard to beat when done right, the active setup will be extensive for SOTA performance and it will be orders of magnitude more expensive..

Interesting. Why do you prefer passive for mid/tweet? Because of problems with the sonics of the active crossover?
Yes i found the sonics and coherency superior with passive xover and of course with good caps ...

There are active designs with external amps. I don't believe that this makes any significant difference but if it did there's an easy workaround. I've never seen anyone dispute the known advantages of active designs.
Imagine how boring the internet would be if folks were as civil here as they are in person.
What known advantage is being disputed ..? What active speaker are you currently using ..?
no known advantages are being disputed because nobody has anything. I've had several active speakers. Currently I have a pair of custom ATC active 110's that have external P-4 amplifiers. It's not really relevant. Microphonics mattered in tube days. Enclosures can be built that don't resonate.
