Do active speakers have high THD amplifiers?

TIM starts w negative feedback. Long ago in a banished galaxy people focused on THD Otalla, Thiel, Vandersteen, a few got time, phase, impulse response…even energy storage and release, perhaps a few…pistonic motion..

Question ; if the cone or a portion of the cone is out of phase to the input ( also known as music ), is that distortion ? 

 I am an investor in a recording studio. Powered speakers are popular at the console, not so much the mixer…editing workstation, even more rare at the mastering level and ATC dominant…at least in the circles i travel….

Our choice ? separate speakers and amps, for mastering biamped w speaker level to connections , about $ 130 range, so yes people do make other choices….I know a gal with a strad…made same choice. OF course those amplifiers are purpose built for the load and not some cheap plate amp. About time and phase, you do understand what a steep slope does beyond output ?

Heavy pop the hood on the Beringer, send me a picture…no Op amps ? ya sure ? My choice for active filters is Modjeski and the brilliant work he did for Beveridge….now those…..sound….good.

finally, i celebrate the diversity of opinion and experience in the thread…. thank God we have an amazing plethora of choice…including which subcult to join…

now, excuse me while i go listen to an ESL that approximates a point source….

pistonic applies to planar, like how do those clamped driven edges load and unload….ain’t nothing free…

Seems nobody understood the question, My question was active speakers and studio monitors have bi-amp, DSP/crossover designs but hide amp specifications except RMS powers. Are they truly audiophile grade or Just boom boxes from reputed Loudspeaker manufacturers? Examples Dynaudio Xeo series, LYD series, Adam audio studio monitors , JBL Kliptch powered speakers.
