The ESL63 QA electrostatic speaker
And why are todays ESL`s named as “QA” models?
It was not enough to understand Peter Walkers philosophy. To get a contemporary version of the famous ESL63 ready to work, a lot of labor was needed. Therefore a new department was established, named QUAD atelier. It has the task to join all the importened components of the original to create new speakers. We spend a new frame, which is far more rigid. and we did some further modifikations. Today each ESL63 QA is made under the ideals of Peter Walker. To say it in short words: “Each ESL63 QA will reproduce a Stradivari close to the original sound”.
