I’m running a pair of Quad 2905s plus passive subs in an actively amplified setup incorporating Roomperfect. It all sounds pretty decent.
However I was recently very impressed ( excuse the pun) by a pair of 11As and am considering a change ( assuming the Lyngdorf digital amp can drive them - there is some doubt on that one).
My question is; would the 11As, or even 13As fit in our lounge ? Which is about 25sq m, or just over 6 x 4 m.
As in the picture I fire the Quads over the 4m width of the room which is essentially one half of the floorspace. The grey wall behind them is 3m across and the panels are 1.1m ( at mid point) in front of it. To the right of the rhs speaker is the other half of the room.
The grey section is, essentially, a wide alcove with unmatched corners. The Quads are about 1.7m apart between inside edges. I sit about 2.5m from the plane of the speakers. The outside edges of the 11s would fire into a couple of metres at least of free space.

Now, the 11s, or 13s, are half the width of the Quads, and from what I’ve read, need less toe in ( try to keep the rear sound wave firing into a corner) . They could be up to 2.2m apart, inside edges. But would 1.1m from wall to panel be enough given the 70cm box depth ?

I would ditch the passive subs you see at the rear if I went 11 or 13A.

110 cm is OK - rule of thumb for Masterpiece - back side of the woofer enclosure should be min the size of woofer from the wall. So you shoul be ok, e.g. 13a 25cm

also 2.2 m is more than enough, i had them at some point 1.8m apart and no toe in, sound was good, on top you have option to use ARC and get bass section controlled. You can also play with forward tilt, this gives nice benefit, if done properly.
 
Actually - 13a’s are not that much bigger in size compared to 11a’s. 15a’s are the big boys.
Difference in performance is much bigger than difference in size - 13a’s are the sweet spot of ML offer in my opinion. You can fit 13a in every rom, where you can fit 11a and they sound significantly better, due to their larger panel size.
