Altec Lansing DRivers and horn

gedlee · 20th November 2012, 08:34 PM

I have a pair of very old Altec 1" compression drivers and the 811 horns that have been just sitting arround for probably 25 years. They are all in perfect condition. Make an offer.

I also have lots of newer P-audio compression drivers and woofers that I would love to clear the storage space of. They have never been used, just tested. I will sell them cheap, but packaing and shiping will not be cheap (I can't control that).

Any specifics on models. I may be interested.

katana2112 · 20th November 2012, 08:52 PM

What do you have for woofers?

gfederys · 20th November 2012, 09:54 PM

Hey Earle, Any B&C 8MDN51 8" Neodymium Woofers? How about crossover parts, caps and such? Thanx.

gedlee · 20th November 2012, 10:31 PM

Altec drivers are standard 1" units - they only made one model back then - w/800 Hz horns.

P-Audio woofers: C15-600EL, SD15
Compression drivers: SD450N, PA D45

No B&C deals, but decent prices (I am a dealer so I can get anything), no crossover parts, I use them.

Uh...no. There is definitely a difference between 802s and 806s. There were also models that used tangerine phase plugs. It would be very helpful to know exactly what they are.

The Altec drivers are way older than Hendrickson's Tangential phase plug design. The drivers have no model number on them any longer. If there is a difference between the 802 and the 806, then what is it? These are very old Alnico magnet designs with alluminum diaphragms.

Similar motor, different diaphragms and loading caps for the 802, 804, 806, 807, and 808.

Yes there is but all of them can be made into one another with a parts swap. If they are as old as Earl is suggesting, they are likely from before the Tangerine.

EDIT: Earl beat me to it. Plus some models of 802 and 808 had a larger motor body. I'd have to look up which is which.

EDIT2: Too much to list here including mislabeled drivers that said one diaphragm but were actually another.

I'm pretty sure all the 802s and 808s have larger driver bodies than the 806s.

Cal Weldon · 21st November 2012, 04:53 PM

You could be right. I know they both changed the length of the bodies when they switched from annular to radial phase plug.

Maybe Earl could post some pics of them disassembled.
