It depends how the manufacturer measures the speakers - the same thing came up with my Audio Note E and prior to that my Audio Note J/SPe.
I can't speak for Zu but in my AN E's case - Audio Note measures "both" speakers in room from a corner loaded position. In other words - what you will get with real world results in the ACTUAL way you will use the loudspeakers in 99% of all cases. The corner of a room adds 18dB of gain in the bass (9dB from each speaker) and 3dB of gain in sensitivity from the corner position. Martin Colloms who is a degree holding engineer and was the measurements taker at Stereophile for years got the same number (in fact slightly better) than AN's published number. Hi-Fi Choice also measured both the J and E and got the numbers AN produced. Only JA doesn't.
Of course - Stereophile measures only one speaker in the middle of a room for sensitivity in a quasi-anechoic manner.
Ask Zu if they get their sensitivity measurement from taking a measurement as a stereo pair (as it should be taken) and that if they measure two speakers - you know why there is a discrepancy.
The easier way is to ignore all this crap and go to a shop carrying whatever speaker you are interested in and connect up whatever 3 wattish amp you intend to use and see what happens. You'll find the ease of drive by using your ears.
I would not not buy a Zu or a Tekton because of a measurement from one source especially one where virtually everything fails - umm if everything fails it's in all likelihood a bad test.
