Altec 820A Corner horn??

[Dylanl]

Does anyone know where I can get a working set of plans for this corner horn? I am also looking for the freq. range of this unit. I have the original brochure but I am looking for the real feel info.

Thanks

Dylan----"How To Build Loudspeaker Enclosures" by Davis and Badmaieff has the plans.

[Dylanl]

This is the one I am talking about:

[Dylanl]

Tom I think this is one the plans are refering to. I also have that set of plans and I have that book. What is the difference in the two this one and the one I show in the other picture. Is there anyone that has currnetly reproduced these? There is one website by a Guy named Scott that says he is building these but he never writes me back when I email. Not much else on the web.

Tom, you beat me to it.

Dylanl, as I recall the 820A used the aluminum H-808 eight cell, 800Hz. aluminum horn with an 802B driver on top. Later versions of the 820 used the H-811 or 811A horn and probably 802C driver.

The demonstration of a pair of 820Cs at the home of an ex-Altec employee was my introduction to "the good stuff" about 20 years ago. They really blew my mind, as I had no idea at the time that speakers could sound that good.

Dylanl, I think the pair in your picture are 820A systems, as they have the H-808 horns. I believe the cabinets are the 821A described in the brochure you posted, with front grills removed.

[Dylanl]

SO they always had that divider? I dont know these just look a little different. Any other clarification or know where I can get working plans?

[Dylanl]

The other side of the brochure looks a little different also, See they show no seperation??
