Something tells me it was University Sound who made the system used in Viet Nam. IRC, 16 drivers on a single horn. Would take a long time for me to find the magazine...

You are confusing two different products.Originally Posted by gvasale
University made I think a 12, 16, and even a 24 driver horn. Just plain ain't what I was talking about.
Lower right:
Buncha El Cheapo screw on drivers, louder than stink and sounded like it too.
I am talking about Giant Voice systems. Way more expensive and way clearer.
And no, University had absolutely nothing to do with the big systems hung from helicopters. They were powered by custom built solid state amps. I saw a couple being built, no way to confuse with the University, it's a toy by comparison.
Went over to unofficial, remembered Todd had a couple TL's on the Giant voice stuff, but the links are not working.
GPA does have a sales lit partial for the stuff. Only pic is 3 multicells in an array with dual 290's

The two systems I saw being built were 203's in a radial configuration each with dual 290's.

Your neighbors called. They like your music.
In a certain movie I'm sure you'll remember the helicopter scene with the horn.

Near the beginning you see it a couple times then again at 2:49
Enjoy.

Nothing like a great big pair of speakers to make your day.

Link doesn't work, but I know the scene. I posted a still photo of those horns a few years back asking what they were. Don't think there was ever an answer.
Now I'd say they were University as shown on the sheet above.

There's a page in the 1968 Altec catalog (that I posted this link for in an earlier thread) devoted to the "Giant Voice" system--some info and photos (also confirms it is definitely an Altec product, not University).....You are confusing two different products.

Being of "Sound" Mind
Electronics World Magazine had a feature article on the University Horn system in ther bottom right of the catalog page. Sometime in the later 60's if I remember correctly. Talked about its use as you alluded to. Altec may also have had something similar, but EW Magazine was all about University Sound in their artlcle. I think I may still have a copy of it, but it would take a lot of time to find it. Not sure if web searches would be productive, and since I don't have the movie, I can't review it or grab a frame shot from the scene in question.
I posted a still here a one time. Will see if I can dig it up.
First, it just plain isn't similar, again you are talking about totally different things. The University is ONE HORN with a lot of drivers. Yes, they saw some military use.
The Altec systems were multiple horns with drivers on each horn. Much bigger, much louder, and much clearer. You cannot compare that University to one of the big Giant Voice systems any more than you can compare a Yugo to a Rolls Royce.
Altec quoted the larger Giant Voice systems at 125 dB at 100 feet...

Well, determined to find a way out of this dilema, I ordered a copy of Apocalypse Now to scrutinize the scene in question, and I also found the Electronics World Magazine I referred to. September 1968, pages 38 & 39. I will scan and post these later, but the article shows a Cessna and a significantly larger Navy aircraft fitted with the University Sound B-24 PT speaker and their own 1800 watt (3 600 watt paralled)amplifier. Claims of "over 148dB @ 4ft, and 80dB @ two miles." I have a 1968 Altec catalog which has an overview of the Giant Voice. I can scan and post that as well. Just waiting for the movie now. Over 43 years since I thumbed through that issue. 19 years old then.
Author of the article claimed this speaker to be developed during the Korean War for psychological warfare.
