Loud Speaker For Auditory Perspective By Thuras

The Fletcher system was the father of the Shearer sound system and all those to come. I've posted about this before but now I wonder if this system survived? Does anyone know if this most important piece of audio history still exists? I pray it is out there somewhere. The construction is amazing. How big is the compression driver on the bass bins? It never ceases to amaze me.
The New York Times reported that "Sound Waves 'Rock' Carnegie Hall As Enhanced Music Is Played" and "The loudest sounds ever created crashed and echoed through venerable Carnegie Hall last night as a specially invited audience listened, spellbound, and at times not a little terrified."

Here is the article on the Loudspeaker Article by Thuras.

    1. This is one of the most important audio systems ever and no one knows if it still exists.... I pray it does!!!!

  3. In 1971 or 1972, I got a look at these speakers in the basement of the Seeley W. Mudd building at Columbia University. By the way, the metal diaphragm pictured in the lower right is 20 inches in diameter. The attached voice coil is 8 inches in diameter. As a result of this experience, I have always thought it would be interesting to build a horn-loaded loudspeaker to hear how it might sound.

    1. Thank you so much Paul it is good to know they have been seen since the 30's. I wonder what the odds are still sitting in the basement.

      Horn loaded loudspeakers are amazing.

  4. What is the date on this article?
