Powered speakers show audiophiles are confused


17 of 23 speakers in my studio and home theater systems are internally powered. My studio system is all Genelec and sounds very accurate. I know the best new concert and studio speakers are internally powered there are great technical reasons to design a speaker and an amp synergistically, this concept is much more important to sound quality than the vibration systems we often buy. How can an audiophile justify a vibration system of any sort with this in mind.

A powered speaker is really the epitome of an integrated, better yet a Bose Wave Radio, B&W Zeppelin. 

I love Genelec speakers (I spent 200k +) but they are only the example of a speaker with the design concept of making an amplifier with a speaker in mind. Meyer Sound is probably the best example of this, Meyer Sound is more of a concert speaker but they sound great. A perfect amplifier only amplifies the weak original signal, it shouldn’t have a sound at all but since the very complex load the speaker gives to the amp the pathway to simple amplitude multiplication is impossible to do unless that amplifier is designed to understand the particular speakers impedance loads and the unique ways that speaker deals with frequency and how fast all this can happen among other things. I’m sure Genelec didn’t make my "The Ones" speakers with perfect amps because they of course have to keep their prices down like everyone else.

The point is that everyone knows curated speaker and amplifier design is proper but very few are doing it because the community of audiophiles are really out to lunch (I am one) we worry about very esoteric things where there are huge design concept that make great difference in proper sound.

Surprised no mention of ATC.

Some of the best sound I have ever had was with ATC Anniversary 50s.

6 Class A amps designed for each driver and active crossovers.

ATC also designs all its drivers and has been building among the best in studios,

performance venues (the Disney, the Sidney Opera House, etc.) and homes around the world for many decades.

They have optimized the advantages of powered speakers.

 unless that amplifier is designed to understand the particular speakers impedance loads 

Can you share with us how an amplifier can be designed to a drivers particular impedance load? Especially one as simple as a woofer which we all know has a predictable curve that rises with frequency quite smoothly.

 

So, this thread is really about active, bundled speakers. While all active speakers are powered, the reverse scenario is not always the case; a 'powered' speaker strictly just refers to a passively configured ditto but with the amp (plus of course the passive filter) built into the speaker.

Great for pro audio use and in studios or for those who want simplicity in a system but most audiophiles want outboard amplification. Also many don’t want to bin a speaker setup because one amp failed inside. My experience with powered speakers failing is fairly vast and while with a few I could repair or replace amps most are junk after just 1 amp fails in a stereo pair. I have built actives but I outboard amplification because of this.

Indeed; active can be with outboard amplification, and obviously also DSP/electronic cross-over and DAC.

Most by default assume and refer to active as a bundled solution, which it needn't be. As mentioned previously one could, with a worthwhile distinction, refer to it as an active speaker or an active system, with the former being the bundled solution and the latter an "active with separate, outboard components." So long as the cross-over is placed prior to amplification it is - by definition - active.

If you like to tinker, great. Tinker with the front end. But why tinker matching amps, drivers, and speaker cables when the engineer who DESIGNED the speaker can do it for you at a much lower cost?

You're restricted having only preassembled, bundled active speakers to choose from. You could do anything really with all sizes and types of speakers choosing an outboard, active solution. Of course this way it's up to each to handle all aspects, but with dedication it's hardly an insurmountable challenge to any existing complexity.

Moreover complete pro segment speaker systems are available sans passive XO's, or you could simply rid passive "hifi" speakers of their XO's and start from scratch with active config. and DSP filter settings. Many an audiophile love to tinker with a range of aspects with their setup, so why not take it a step further and master your own filter settings? 

And I second the praise for Meyer Sound speakers.
