Here's a little cut and past of my studio speakers on some of the benefits of being powered in just the crossovers. A small part of the design.
The active crossover design offers multiple benefits:
- The frequency response becomes independent of any dynamic changes in the driver’s electrical characteristics or the drive level.
- There is an increased flexibility and precision to adjust and fine tune each output frequency response for the specific drivers used.
- Each driver has its own signal processing and power amplifier. This isolates each driver from the drive signals handled by the other drivers, reducing inter-modulation distortion and overdriving problems.
- The ability to compensate for sensitivity variations between drivers.
- The possibility to compensate for the frequency and phase response anomalies associated with a driver’s characteristics within the intended pass-band.
- The flat frequency response of a high-quality active loudspeaker is a result of the combined effect of the crossover filter response, power amplifier responses and driver responses in a loudspeaker enclosure.
There are so many reasons why powered and active speakers are the future the sports car analogy is one most audiophile understand. Everyone knows powered speakers are the future in every category of playback, I started a thread about how audiophiles were confused about powered speakers, 65k views later people still didn't have a clue. Yes you can put a "A" or "AB" or whatever kind of amp you want in a speakers you just need big heat sinks (Pass did it).
Look at it from this point of view, today speaker cables cables are becoming some of the largest costs in a system, assuming that this is a proper use of audio money then why not bypass the cables completely. If there is merit in the idea that cables create such a huge deeper, wider, higher, lower, more accurate, tighter bass, blacker backgrounds, more musicality which is caused by hyper priced 1 meter speaker cables then why not do without cables all together just think of the musicality then wow. For that reason alone (if it is valid) designed powered speakers make sense.
