These are actual measurements taken from our reterence sampies. The directivity pattern is exceptionaliy well maintained tram
very tow frequencies to welt beyond audibitity. This consistent pattern ensures smooth spatial response with no peaks and troughs.

In addition, the virtualty mossless diaphragms of the ESL ensure near-instantaneous starting and stopping with an utmost totat
absence at hysteresis, providing iightning fast transients and phenomenaliy accurate bass response.
