Powered speakers show audiophiles are confused

Can you give an example of a 3D movie that you think is a good example?
 

@kota1 I'm sure there have been no movies done in that way. Of course Jim Cameron movies are the best 3D examples. I was going to present binaural recording to Cameron but it would be to much of a jolt listening to sound from a real point of view in a movie. I worked in the same studio for the last 7 years as Jim Cameron while I was doing sound on CSI Miami and Scorpion in Manhattan Beach CA. That technique would not do well for multi camera shoots, and it's hard enough to get a boom mic over an actor let alone a human size head, it would probably be distracting to some actors also.

Checkout the Kraftwerk 3D blueray, 3D video with a great atmos soundtrack

Back in 1999 I had the idea to build a fully horn loaded speaker system with the bass being played by folded corner horns back in the corners and mid range (actually wide range) and super tweeter horns being well out into the room where they could image better.  Obviously DSP was needed to correct the large distance difference between the various horn drivers.   It was 2004 before I found a DSP unit which would do everything I needed at a price I could afford.  That DSP was the initial commercial offering from DEQX.  I built the system then.  It was initially somewhat disappointing.

Over the next thirteen years I changed woofers, folded corner horns, midrange horn drivers, added horn super tweeters and went through six different changes of amplifiers as well as upgrading the DEQX.  I ended up with Bill Fitzmaurice designed HT Tuba folded corner horns driven by a good Dayton 15” woofer.,   BD Design Oris 150 horns driven by AER BD3 8” drivers and Fostex t900a bullet supertweeters.

  I programmed and reprogrammed and reprogrammed the DEQX over and over.  Programming the DEQX  is neither quick nor easy.  I had the system sounding really good, but I always felt it could be better.  Then in 2017 I engaged the services of a DEQX company approved DEQXpert, Larry Owens,  Mr. Owens, a very smart man, connected his PC to my PC which was connected to the DEQX,  and we communicated via a Skype call while he did speaker calibration and correction, time and phase correction, room correction and crossovers.  If I remember correctly he took a total of about six or seven hours in two or three sessions to complete the process.  Crossovers were set at 200Hz and 8 kHz with all roll offs being 96 dB/octave.

The speaker/amp system finally sounded as I had imagined it back in 1999.  Modesty prevents me from using all the superlatives I feel my system deserves, but when fellow audiophiles come for a listen and say things such as, "that's the best I ever heard that song" I am immensely gratified.

Thus I have an active system with drivers and amplifiers of my own choosing with every element being easy to change.  I think I have the best of both worlds.  Besides that the system is not ugly.

@kingharold Thanks for the story, you make me really want to seek out horns. Glad you understand active speaker synergy, I feel like it is a step into audio reality away from arrogance. I just can't imagine someone paying so much money for speakers/crossovers and amps that aren't designed for each other. You seem like exactly the opposite of a person who simply pays a lot of money for flashy audio equipment without considering the objective details.
