Help identifying these vintage electrostatic speakers? Found them in a consignment shop in San Diego. Thought they had a really interesting design but no branding I could find. : r/vintageaudio
My first pair of Electrostatic Speakers (Infinity). Found them for $40 today while out with my daughter. She said the instruments sound like they are "alive". : r/audiophile
