Beautiful pair of famous Acoustat X electrostatic speakers. Lovingly restored frames and grilles. I've sold the servo amps for these separately, so they don't have amplifiers. They would be great for someone wanting a speaker like the model 3, someone who wants to add a servo amp or Acoustat interface to existing panels or someone who wants to build a custom pair of speakers based upon Acoustat panels. Local pickup only in Portland, OR or I can meet in the Pacific NW within 150 miles.
