Both pretty good overall measurement.

Both should sound good.

Measurements is one thing - however, my main concern is how do they sound.
I prefer to listen with an open mind - if the speakers sound good in my room,
and if they do not annoy or distract me, then I will be fine - regardless of any
printed measurements. My final decision is based on real sound, not perception
from just reading measurements.

However overall, those speakers measure nicely - and should sound good.

The vertical response of the R700 is the best I can recall seeing- wow!

the revel performa was measured up to 45 degrees off axis. the kef was measured up to 15 degrees off axis. I don't know which is better measured response though. Probably Kef cause it's straighter?

Tower vs Bookshelf maybe the reason for the difference in off axis measurement

Which is not inherently good or bad, but with the majority of homes having fairly short distances between ceiling and floor i'm not sure this is a plus. Early reflections from the ceiling and floor will be more prominent and have the potential to negatively affect timber and perhaps even soundstage size.

On the flip side of the coin, a WWMTTMWW such as the Dynaudio Evidence Master has a pretty narrow vertical throw but nice and even horizontal throw.

The limited vertical dispersion as one moves above the tweeter axis will reduce harmful early reflections from the ceiling in the critical 3-5khz range.

Likewise, look at the verticals for the Dynaudio Temptation:

As one moves above or below the tweeter axis SPL starts to decrease quite rapidly.

I do so love coaxials, though. I have heard the Blade and the R900 and I enjoyed both. I have also heard the Dyn Evidence Master and enjoyed it quite a bit.
