E167: Southwest Audio Fest 2024-Best Sounding Rooms-High End by Oz

[@davidwrobinson5229]

A really fine, coherent video report, Greg! Well done!

[@theaudioanalyst]

David, thank you so much...

[@amandela55]

Dr. Weaver. What a great show report video. Oz really knows how to put together a great sounding system. Well done.

[@theaudioanalyst]

Thank you so much, my friend. They really hit a synergistic home run with this event...

[@ozanturan9741]

Thank you @amandela55 for the kind words

[@audio_acoustic_engineering]

Great review of the hotel, interview and what a system! I enjoy listening to United Home Audio’s music collection on Oz’s system, it’s such a pleasure.

[@theaudioanalyst]

Thanks for the kind words on this episode... As you are well aware, these cats always play some great music. But this room and system just synergized and made some fantastic sounds! Such a great exhibition for them...

[@ozanturan9741]

Thank you @audio_acoustic_engineering. We try to play variety of music at shows. Glad you enjoyed it

[@adsph]

Thanks for the detailed info on this room. Hope to visit them at Axpona.

[@theaudioanalyst]

Thanks for watching and commenting... If you see me there, please introduce yourself and say hello! ☺

[@adsph]

@@theaudioanalyst will do

[@ozanturan9741]

I want to let you know that we are not going to be axpona this year.. our next show is going to be at THE SHOW in Irvine,CA then capitalaudio fedt in November

[@adsph]

@@ozanturan9741 perhaps next time. Thank you.

[@johnsonadekunle7675]

Nice meeting you at the Dallas southwest audio show. I'm the guy that mentioned the Django XL speakers.

[@theaudioanalyst]

Hello, John. Thanks for taking the time to introduce yourself and chat. Did you enjoy the show as much as I did? 😁

[@johnsonadekunle7675]

Yes I did. Believe it or not, it was my first time attending an audio show.

[@theaudioanalyst]

@@johnsonadekunle7675 OMG! How very exciting is that? And, what a great first show to experience... I'm already looking forward to next year's event! See you there? 😃

[@johnsonadekunle7675]

I should be there next year.

Would you happen to know why Lansche has not developed corona plasma drivers to cover the entire frequency spectrum? I too enjoy the Southwest Audio Fest immensely.

[@theaudioanalyst]

That would be a question for Lansche, but I suspect that it has something to do with the practical limitation of physics and the technology necessary to do so. Do you recall the issues Nelson Pass faced when he built a prototype corona wind loudspeaker that he called an Ion Cloud panel? It was an ion/plasma speaker... massless.info/DontBreathe.html

Worth clicking the link for the pic of Nelson as a younger man! ​@@theaudioanalyst

[@marcus1970]

Amazing looking building. Stella had much to contribute to your explanation of Corona Plasma tech and presentation. Wonder if She'd appreciate first hand(paw) the upper registers being present from this tech?

[@theaudioanalyst]

@@marcus1970LOL... Yes, she was so busy barking at delivery drivers, neighbors cleaning up their lawns, and kids playing, riding their bikes, and walking their dogs, that there was very little chance of keeping her quiet...short of locking her downstairs or out in the back 2-acre yard... I opted to let her have her say, the little stinker! 😊 Hopefully, no one will find it TOO distracting!

[@anthonybertolami3888]

@@theaudioanalyst Oz’s presentation addresses the safety issue convincingly , and I appreciate your comments on the challenge of seamlessly engineering the drivers in previous designs.

[@carlosoliveira-rc2xt]

When are people going to stop expressing efficiency in decibels? Sensitivity in dB and efficiency as a percentage.

[@theaudioanalyst]

A speaker's efficiency is the measurement of how effectively it converts an electrical signal into acoustic output. And while that relationship may be expressed as a percentage, as that percentage is typically about two percent or lower (for the more standard dynamic cone type driver), it is not seen as being a particularly useful specification given its resultant limited scale. But by the mid-1970s the established standardized method of assessing a loudspeaker's efficiency was to deliver precisely one watt of power to the speaker and to measure the resultant amplitude of the output with a calibrated microphone and decibel level meter placed precisely one meter from the speaker. The resultant output level that results is considered to be a more useful expression of the speaker's efficiency rating, and because it includes the cabinet interactions with the drivers as well, it also offers a clearer expression of the speaker's overall sensitivity given the finished loudspeaker’s choice of mechanical loading.
