Dont look at the overall dimensions, but the phase plug is measured from the altec 288-16b

E.C. Went is a name I will not forget.

If only this information could be written in stone. Time has a way of erasing information. Perhaps it should be etched into stone?

I've been collecting information on horn design for a few years (on and off) for personal use. I will definitely add a few of those pages to my collection.

Afaik, E.C. Wente did not "invent" the compression driver.

The compression driver predated his work. He improved the design.
Made it practical for higher SPLs and wider freq range, lower distortion.

Hello Bear,

I fully agree with you

Mechanical drivers using compression chambers were yet used in phonographs.

The most important inventor for compression drivers, diaphragms, horns of begining of the 20th century was IMHO Harrison : see here something like a compression chamber :

http://en.wikipedia.org/wiki/File:Ha...cal_filter.png

Norton probably invented the first phase plug :

After the triode was invented and the need for electomechanical drivers (then later "loudspeakers") Whente, Thuras and the others used to develop their ineventions from many things yet invented for phonographs (metallic diaphragms, compression chambers, phase plugs, horns...)

Best regards from Paris, France

The mouthpiece [1] of a "brass" musical instrument, when combined with a pair of human lips, is probably the very first implementation of an acoustical compression driver. Note that a "brass" musical instrument does not have to be made of brass. Any horn that generates sound from the buzzing of the player’s lips into what is generally a cup-shaped mouthpiece is considered to be a "brass" instrument.
