Will the HW-Q950A work in my room?

[RichD1]

I have a thro' lounge diner measuring 7.5 mtrs x 4.25 mtrs wide. The area is split roughly 60/40 in favour of the lounge. The original dividing wall has now got a large arch between but the sides and ceiling are not continuous. The TV is located diagonally in the far corner next to the fireplace and to the other side is an open doorway through to the sun lounge. Main viewing point is diagonally opposite the TV and about 3 mtrs from the screen. We have two settees in the room, one facing the fireplace and one right under the dividing arch. Ceiling is 2.5 mtrs but as I said not continuous.

We watch mainly TV and movies and my existing Denon/KEF eggs don't provide good dialogue clarity and gets lost in the background music or action sounds.

Would the 950A provide good performance is this shape of room?

Or is there a better solution.
