I have some Cornwalls and EV Dominators, but these are my favorites. The stand is missing. I think it sunk in the San Francisco bay.
Wow, have you ever tried to operate this? Do they have rotary motors inside, or are they a linear motor with diaphragm setup?

Diaphragm.
The largest of the three diaphragms is cracked, so I need to order a new one ($65). I waiting to find someone with a forge and the proper skills to straighten out the bent bell without cracking the bronze.
Here's the specs for those of you who might care:
6" -
Wt. - 26#
Air Consumption - .45 cu. ft./sec. @ 40-140 psi
Freq. - 190 cycles per sec.
120 db @ 25'
Audible range - 2 1/2 - 3 1/2 miles.
8"
Wt. - 45#
Air Consumption - .85 cu. ft./sec. @ 40-140 psi
Freq. - 168 cycles per sec.
120 db @ 25'
Audible range - 2 3/4 - 3 3/4 miles
10"
Wt. - 70#
Air Consumption - 1.4 cu. ft./sec. @ 40-140 psi
Freq. - 140 cycles per sec.
123 db @ 25'
Audible range - 3 - 3 3/4 miles.
The "horns" sit on a ported manifold (about 50 lbs) with a 2"intake. Each horn has it's own "crossover" (inlet port restrictor) for fine tuning. The current diaphrams are brass, but I may replace them with stainless steel, which the mfg. now uses.
It will take a 160-185 CFM compressor to "properly" operate. I have a couple 1300s in the yard right now.

I didn't even think about air....... I had no idea an air operated horn would use a diaphragm.

And that's not counting the additional 12 Frazier horn tweeters sitting in a box, or the ones that have left the building, like the Fortes, Choruses, CWs, and Frazier Mark V's....
Is that a Stromberg Carlson integrated amp I spy in the garage? Nice. John
Here's a pic of my set up with a pair of speakers that have wood horn tweeters:

Absolutely, I'm surprised those aren't up in the trees, already. Halloween is just around the corner. Need wire?

I was planning on tying a chain to them and dragging them around the block a few times first. Then, I will take you up on your offer, Lance.

I'm sorry, I thought you appreciated audio gear. I don't know how many times I've seen people get something in good condition and then put it down on abrasive cement. It makes no sense.

Concrete (or cement as you refer to it) is only abrasive if there is movement between it and whatever rests on it. I can assure you that the horns were not moving during the few minutes they sat while I got them out of the van.
I wouldn't do that with a wood cabinet, but a durable paint finish can withstand the "punishment" of sitting on concrete for a few moments while I take a couple of pics and unlock the door to the house.
No children, animals or horns were harmed during the process.
Thanks for your concern though.

The bigger ones are still work in progress. Just hooked them up to tweak the crossovers.
