gearfreak Posted April 16, 2008 Share Posted April 16, 2008 Howdy all, I've just aquired some 511 style horns. They have lost the labels, but based on the Peavey 22a drivers and adapters, would seem to be 1", thus 511B? I've been perusing the LH site, but not finding any definative guide of sorts. Anyone have hints for ID'ing whether they are 511B, 511E, etc. ? Any comments on what to do with the 22a's? Have not fired them up yet to see what they sound like as is... thanks Quote Link to comment Share on other sites More sharing options...
Marvel Posted April 17, 2008 Share Posted April 17, 2008 The 511E has a 1.4 inch throat. Quote Link to comment Share on other sites More sharing options...
gearfreak Posted April 17, 2008 Author Share Posted April 17, 2008 Thanks Marvel, Do you happen to know if they are the only 2 designations? 511B and 511E ? I'll measure tonight. Got started cleaning them up and got the 22a's off and was intrigued that the horn throat looked smaller (smaller) in dia. than the driver's. (maybe there's a 511 with a 3/4" throat?). Enough conjecture.. I'll shut up and just go measure... :-) Quote Link to comment Share on other sites More sharing options...
Blvdre Posted April 20, 2008 Share Posted April 20, 2008 I believe the 511A was green and also had the 1" throat, for all intents and purposes the same as a 511B. Here's a helpful website for all that is Altec. It's a bit hard to navigate, but be persistent, you'll find what you're looking for. http://alteclansingunofficial.nlenet.net/ Quote Link to comment Share on other sites More sharing options...
gearfreak Posted April 21, 2008 Author Share Posted April 21, 2008 Thanks all. These are black and have the 1" throat. The holes/throats in the cast aluminum 2 bolt adaptors that fit the 22a appear to be machined from 3/4" at the driver to 1" at the mating point with the horn. Thus not a good match with the K-55-V? I'll look up those selenium adaptors and see what they are... Quote Link to comment Share on other sites More sharing options...

HarryO Posted April 21, 2008 Share Posted April 21, 2008 all series horns were available in most colors. Harry Quote Link to comment Share on other sites More sharing options...
Blvdre Posted April 21, 2008 Share Posted April 21, 2008 Thanks for the correction Harry. Bill at Great Plains seem to think the 511A's only came in green. BTW, I love the green horns. Quote Link to comment Share on other sites More sharing options...
HarryO Posted April 21, 2008 Share Posted April 21, 2008 I went through the same thing a couple of years ago. Some of the Emilar built designations are very confusing. I've also have or have had "B" pairs of gold, brown, and black to go along with the greens. I have or have had the "A" models in the same colors except the gold. Some of the very old Seeburg Jukes remote speakers had the gold "A" I'm told but have never seen them. My thinking is "Long ago companies would go out of their way to please customers" You could probably get any color you wanted just by asking.

gearfreak Posted April 22, 2008 Author Share Posted April 22, 2008 Such a nice green. Alas, these are (flat?) black. When repainting, is there a flat/satin/gloss preference? (for sonic not cosmetic reasons) thanks! Quote Link to comment Share on other sites More sharing options...
ZAKO Posted April 23, 2008 Share Posted April 23, 2008 You can chrome plate them for sonic reasons,,, Make them sound brighter !!! Quote Link to comment Share on other sites More sharing options...
Blvdre Posted April 25, 2008 Share Posted April 25, 2008 You're pure evil, Maron. Interesting about the different colors, Harry. The gold I've seen - nice and flashy. I was wondering about re-painting myself, might be easiest just to cover the flat black w/flat black. I'm also wondering if these horns might benefit from a coating of spray dampening on the outside.

gearfreak Posted April 25, 2008 Author Share Posted April 25, 2008 We've seen other altecs with some sort of dampening coating. I wonder if it is the same spray rubber as from the auto store (for your undercarriage) or some special audio sort. I don't think the auto stuff really dries (ever). Maybe a godo thing, but could get messy. I think I will probably do satin on the interior, after some sanding or steel wool to remove existing imperfections. Maybe they'll look nice in raw aluminum though and I'll have something close to Maron's suggestion. Quote Link to comment Share on other sites More sharing options...
Marvel Posted April 25, 2008 Share Posted April 25, 2008 I have some Yamaha horns that arebare aluminum with a clear coat of some kind. I would try them in something, but they are 1200 Hz horns. A bit higher than anything I want to use. Bruce Quote Link to comment Share on other sites More sharing options...
JohnA Posted April 25, 2008 Share Posted April 25, 2008 The 22As are tough, high power midrange drivers, at best, little above 10k. My brother has a pair mated to FH-1s I'd put them on eBay. Quote Link to comment Share on other sites More sharing options...
gearfreak Posted April 30, 2008 Author Share Posted April 30, 2008 Thanks John, maybe they can (start to) fund some 902's for me. :-) Quote Link to comment Share on other sites More sharing options...
