The Quad 57 are excellent loudspeakers (one of the all time greats!!) but have now reached an age where they can become temperamental and misbehave. The Quad 57 repair kit has been designed to address the most common issues found with faulty ESL panels, namely, low or distorted output from one or both speakers and strange noises such as hissing, clicking, popping etc.

Our repair kit contains sufficient diaphragm material to re-diaphragm all panels in a pair of Quads, replace the dust covers and still have some left over.

The following kit is supplied for home use only and may not be used for commercial gain unless authorised by ER Audio in writing. All photographs, drawings and text contained in the kits are subject to copyright laws and may not be reproduced or copied in part or in full without written permission from E R Audio.
Acceptance of any kit implies acceptance of these terms.

Now better value than ever.
The kit now includes 6 metres of 800mm wide x 6um thick heatshrink material for dustcover repair or upgrade.
This is much thinner than the original Quad material and improves the high frequency and transient response
of the speaker.
