Hey, hey, Anyone here using old Altec-Lansing speakers still? An old retro theater or club perhaps? Later, Gator

Hey, hey, Not buying or selling just curious. I know some are using Altec gear on SETs for hifi rigs but wondered if anyone used Altec for live sound or theaters anymore. Did a search here and on AA and didn't see anything like that. Does Great Plains Audio sell to pros or is it mostly DIY'ers? Later, Gator

Nope not anymore. Back in the mid and late 70's I used them for main PA's for bands. After a while running them at or near there full rated RMS power they'd start self destructing. So they earned the reputation as Altec Self Destructs in my book. After looking into those blown drivers, it looked more like it was a thermal problem. Like heat getting built up in the gap melting the coil glue and letting the coil weld itself to the pole piece. But I've had good luck running other drivers in there cabinets and horns with no problems. The only way I'd use Altec drivers now days would be in a home stereo enviroment, nothing live.

I wonder what you were doing to those Altecs to melt them. I ran PA for 10 years (indoor and outdoor) with a pair of Altec A-7 500s driven by a Dynaco Stereo 416 (200+ watts per channel). Opera, Country and Western, a Rock Band, soloists, Choirs, you name it. Never had a failed element. One year a horn was stored face up and water ran in and froze so I had to get a new diaphragm/coil assembly. Another time someone poured a cup of coffee down the throat. I drained it and had no trouble. I still use the speakers with no trouble. Of course you have to realize that the tweets are only rated about 15 watts continuous, but they will stand huge overloads for short (musical) periods. Same for the woofs only a few more watts.. Now if you feed them 60 cycle hum at ear shattering levels I can see them melting after a while.
