Question B&W CCM663 —dispersion range?

[OriginalCin]

I have an existing 7.2 dedicated theatre with B&W 705s2 all around plus two SVS SB3000 subs.

I’m gonna install a pair of CCM663 as Atmos speakers, but I’m unsure of the best ceiling placement.

According to Dolby, any wide-dispersion speaker can work, but you should stay inside the primary sound dispersion zone for that speaker.

Does anyone know the dispersion range — or how to calculate it — for the CCM663?

According to the manual the tweeter is aimable up to 30 degrees, so it can be pointed towards the listening position.
In addition there is an EQ setting to increase the dispersion
