My choice - I had a Beolab 8000 + Beolab 2 combo before and the Beolab 9 without subwoofer is the better choice.
I suggest a Beolab 7-4 as center speaker (run this in my cinema room with Beolab 4000 as rears).
(In the living room I have a Beolab 7-2 with Beolab 9 (and 8000 as rears) and I feel the Beolab 7-4 in the cinema room is the better choice - not sure if this is due to the room?)
