About the X
The Acoustat Model X is a pioneering hybrid electrostatic loudspeaker system introduced in 1976 by Acoustat Corporation of Fort Lauderdale, Florida. It combines electrostatic panels with a built-in valve-based servo amplifier and high voltage power supply in a single integrated unit. The system is designed to deliver the coherence and musical detail characteristic of electrostatic speakers with the convenience of integrated amplification. The Model X represents Acoustat's first commercial product and established the foundation for the company's reputation in electrostatic speaker design. The speaker features a wooden console cabinet and operates on standard AC mains power (120V 60Hz or 220V 50Hz).
