I've not heard the 9.2 myself, but here are some measurements that might be of interest.
The Google translated text is:
"Was Canton with the predecessor a spectacular litter succeeded, this is even more true for the optimized Reference 9.2. It would be difficult to find in the noble class of the compact a universal usable box than this. Audiophile, balanced and dynamic sound! Fantastic.
The amplitude frequency response shows what you hear: Here everything is right, there are no break-ins or exaggerations, the box reproduces straight-line and balanced down to 50 hertz. Even off-axis, the high-tone waste is extremely minimal, the omnidirectional behavior thus excellent. We recommend stand installation and easy angle to the listening position. The efficiency of 83 dB is average for a speaker, but good for a compact speaker. Excellent is the step response, which shows a perfect, virtually flawless timing of the two chassis - and explains the equally inspiring as credible liveliness of the lecture. The impedance curve reveals a minimum of 3.2 ohms around 50 Hertz, which is standard - but a stable amplifier can not hurt!"
