Default FS: Audiostatic ESL aluminum cross bars

Still cleaning out the closet...
I have (134) leftover aluminum cross bars used to build Audiostatic style ESLs.

Bars are approximately 9 3/8 long made from:
Extruded 6061 T6 Aluminum Square Bar (1/4 x 1/4)
I had them black anodized locally.

$20 gets the whole lot.
Buyer pays actually shipping cost. Should fit in USPS flat rate package.

Thanks for looking,

Steve

I'll be selling them at the local scrap metal yard next Saturday if nobody is interested.

Hello Jam,

The 2 sets of ESLs that I built with these crossbars are essentially Audiostatic ES-100 clones. The main frames were made from phenolic, and the pictured aluminum crossbars were used just like Audiostatic. The only differences were that I used a small gauge PVC insulated wire and spaced them closer together than on the ES100. I also used only about 1/2 the diaphragm to stator spacing that Audiostatic did to pick up some sensitivity. I used an electronic crossover to remove the diaphragm resonance peak and cross over to a pressure subwoofer at 70Hz.

Hope this helps,

Steve
