Sound Lab

The Finest Electrostatic Loudspeakers

This is the statement speaker product from Sound Lab and is regarded as the finest electrostatic loudspeaker ever made. It offers the most transparent, true to the source sound, one can experience. It has no crossover and Sound Lab electrostatic speakers are the only single transducer, full-range loudspeaker in existence. 

The U-1PX not only incorporates Sound Lab's latest electrostatic panel and electronic technologies, it also incorporates a massive steel frame to protect and preserve the critical tolerances of the electrostatic panel. The heavy duty frame employs three-inch diameter steel support posts that are solidly connected together with 1/2" thick steel brackets, terminating at floor level with spikes for solid floor coupling. The high reactive mass of the framework eliminates frame vibrations, thus eliminating frame resonance and insuring that all sonic energy is converted to music.

The massive steel frame of the U-1PX not only provides technical benefits, but it also manifests a unique space-age beauty. A wide range of finishes and grille fabrics are available.

For the absolute sound, the Ultimate PX electrostatic loudspeaker from Sound Lab provides clear advantages. It offers the most realistic reproduction of sound that modern technology can provide. We have used Sound Lab electrostatic technology in our reference system in our main studio since 2006. Our guests have thoroughly enjoyed the astonishingly realistic music they reproduce, and we have yet to hear better.
