The KEF R700 does measure well but the tweeter still has some hash and is not nearly as clean as the Seas Excel Millenium tweeter - see the outstanding lack of resonances (much better than any metal dome) in the waterfall plot for this speaker with the Seas Sonotex dome in their Excel Millenium tweeter (around 200 euros each!)

You need to look for a clean waterfall with fast (damped) decay and no hashy stuff or resonances. The main resonant ringing is not normally in the audible band - my concerns are the additional resonances and lack of damping in rigid domes. The titanium dome on the JM Lab Utopia is up to 2 msec across the treble - this is a lot of vibration compared to something mostly clean or down 20 dB after 0.5 msec.
