No problem, the Q series has been continually updated and refined and I believe this is their 8th revision.
I tried to find an impedance response graph online but thus far have been unsuccessful. I found the previous version(Q900) graph and the dips are down to under 4 ohms from 90 to about 300 Hz. A fair amount of the response is under 6 ohms as well. I’d say that almost half of the frequency response is under 6 ohms.
Google Stereophile Kef Q900 review, the the specs of the two models is quite close I believe. I only went with the Q750 because my room is not large.
