ESL 2912X

Electrostatic Loudspeaker

The ESL X concept began in 2019 as part of an intensive review of the QUAD Electrostatic manufacturing facility—a suite dedicated solely to the production of QUAD ESL loudspeakers.

The ESL 2912X is the flagship QUAD electrostatic loudspeaker. Featuring an expanded six-panel design for increased radiating area, higher sound pressure levels, dynamics and extension, the ESL 2912X delivers an immersive listening experience with deeper bass and rich textures, bringing even the most complex music to life. Built for the ultimate audiophile experience, it offers enhanced dynamic range, improved headroom, and a spacious soundstage.
