Their general stated sensitivity rating is 90db. Which is on par with the Axioms. I know some 3rd party measurements of the earlier M3 was stated at 86db but haven't seen anything from the V3 model but it is stated at 92db and 96db (in room). Of course, in room, these ratings will change. It is possible that your Cambridge model speaker is more sensitive. Not really a big deal either way IMO.
Iím armed and Iím drinking. You donít want to listen to advice from me, amigo.
