Quad ESL-2812 Electrostatic Loudspeakers

Description

ESL-2812

The ESL-2812 is the smaller, more compact electrostatic speaker produced by Quad.

The original ESL is a most iconic loudspeaker: The world’s first full-range, ultra-low distortion electrostatic loudspeaker, which set standards for accuracy and fidelity in loudspeakers that remain unsurpassed to this day.

A labour of love for founder Peter Walker, the ESL-57, as it came later to be known, is still revered by audiophiles all over the world.

ESL is the complete embodiment of the Quad company ethos – "The Closest Approach To The Original Sound" – reproducing a sound which is indistinguishable from having the performers right there in front of you. The latest models (ESL-2812 and ESL-2912) have built on the original concept with improved efficiency.

Quad

The history of Quad is one of technical achievement in the field of sound reproduction. It is a story that began with their first amplifier, which applied fifteen years of knowledge and experience in professional audio and industrial products to the task of making the most accurate domestic audio amplifier of its age.

Every product in the Quad portfolio of amplifiers, headphones, moving-coil loudspeakers and electrostatic loudspeakers have received international acclaim. However, Quad has never indulged in technical one-upmanship. Their technology exists for a purpose that has remained constant over the years - to reproduce music in a form that is the closest approach to the original.

Unilet Sound & Vision are one of the longest-established official Quad dealers in the UK, and one of only a handful of dealers for Quad Electrostatics in the entire country.
