Zu Soul Supreme sensitivity

Posted by rockdoc on May 25, 2017 at 13:28:39:
The Stereophile review of the Zu Soul Supremes shows test results at much lower sensitivity than advertised by Zu.

JA- "My estimate of the Zu Soul Supreme's voltage sensitivity was 91.5dB/2.83V/m, which is lower than the specified 97dB/W/m but still much higher than average.

Zu publishes efficiency as 101 dB.

Who's right?
