Are these Altec cabinets?

[gearfreak]

IIRC I had used an Audiovox PS-3 for some of the L'pais. 12v 3a regulated. They pop up now and again.

If you want an easy way to test the effect of increased/decreased voltage, something like the Xantrex/Sorensen XT 30-2 has big fun numbers and knobs and is fan-less.
However my 2 of them physically hum, don't know if that's a flaw or they all do that. Their numbering is representative, e.g. up to 30v @ up to 2a for the model above.
With one, you could probably run several (or scores?) of chip amps? I was running 2x stereo 60wpc rackmount (not chip) amps that had worse power supply noise issues, and they didn't break a sweat per the amperage readout. ...that was with multiple relatively HE Altec's and not at concert levels though.

I?ve been bugging this guy for pics of the horns he has to go with the cabinets. He finally emails me a pic today. Green 811 horns/802D drivers with a pair of JBL 150-4c woofers. All very very clean looking. Obviously not all for 200$. I don?t even want to know what he wants for the drivers, but I?ll have to ask. Probably more than I?m willing to pay.

Pi$$ poor match up, woofer's designed for 500 Hz or lower........

True. It would be an odd setup. I’m wondering if the woofers he has even came out of these cabs. He said in the ad they had an Altec setup before
