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.

It is very difficult to listen for transparency

For YOU

because our (replace our with @thespeakerdude ) detailed audio memory is so short that we have a very hard time comparing

clearly there are several people commenting on this topic who are far more knowledgeable and experienced than you are

Of course there is, otherwise I wouldn’t waste my time in this thread. The people I am gaining knowledge from have all posted their creds. You are making it up as you go along IMO.

I would suggest you lose the attitude

I wouldn’t have an attitude if you posted something besides a fantasy system from your made up job designing invisible speakers, PLEASE prove me wrong OK?

Everything I make claims about when posting I either link to evidence or it is based on my own system which I have posted. When I call out rudeness I respond in kind, your insults to @phusis are ridiculous as he has backed up his claims by posting his system. You are just dancing around spewing insults with nada to back it up besides a keyboard so I called out your nonsense.

 

 

 

There was nothing rude in a teacher correcting a student who has made an error, or correcting someone using a 1990 snapshot of battery technology to comment on electric vehicles. Knowledge is never rude. Taking attitude with someone where you lack knowledge is rude. If you would like to fix that issue, here is a quick smattering of papers that provides a cross section of what active speakers means to those working nearer the forefront of the field. This is by no means an inclusive overview, but it is a good start. When you have read all of them, and fully understand them, including why in almost all cases they require tight coupling of the amplifier to the driver, then we can continue this conversation.

A convenient pressumption to make the narrative fit to your needs. Come on..

How would you listen for transparency? What does it sound like? Have you heard it before? Do you know what relative distortion sounds like in a speaker over any given frequency range? at a particular sound intensity? What would you use to listen for it? Do you know the pedigree of that recording and the signal / processing chain to know the level of transparency from the time the sound was created till it comes off the recording medium?

I'm shooting sparrows with cannons in my systems approach in several areas, and don't have to proof nor explain anything to you with regard to my discerning abilities. The questions you're asking however tells me you may be working from a physically limited framework where it least some of the mentioned parameters will be all the more challenging and press upon themselves to be addressed - more "creatively," even. 

Again, you haven't yet addressed my plead: give me/us something to go by with a range of speakers that meet your criteria in being fairly faithful to the signal presented to them in a given acoustic environment - then we'll see what you're up to and what it really amounts to. It should be clear to most that you're knowledgeable, but so far it mostly comes down as show-off and telling people what they're missing out on. I surely mind being a bitch to that attitude of yours. 

When you understand the intricacies of driving a traditional dynamic driver or AMT in the most linear possible fashion, at all signal levels, with complex waveforms, perhaps your attitude will be warranted.

No, you need to show something by example here. 

.. and probably most people's concept of amplifier/driver is a simple linear voltage based amplifier perhaps with some frequency response modification. Without writing a book, that is a traditional view that is not the future of active speakers. Even active subwoofer drivers with velocity/position feedback already break that mold.

That's a preposterous claim before even realizing what's here. The future of active configuration is first making it more known and widespread in its varieties to the users in domestic sound reproduction. There are bundled solutions. Outboard. Pre-assembled. DIY. Small and large iterations to pursue - the latter if one truly chooses. You want to jump the fence from passive to your way of "shine a light" active as the only thing that really does it - in what form or shape? Details, please. There's a lot in between or even beyond. I've chosen DIY outboard-active from a relatively unrestricted package physically. It goes to show the importance of physics with subs in particular; below the Schroeder frequency it's about capacity, proper design/construction and implementation mainly. The larger the cumulative cone area the less cone movement is needed for a given SPL, and in effect less inertia build-up, more headroom, lower distortion, ease of reproduction and all that jazz. Not to mention attention to room-loading with DBA's, column sub solutions and/or more extensive room correction digitally. Servo drive needn't apply here, not that the effort isn't well-intended. And so on..
