Hi sirquack ,
my room dimensions are
Width: 4.20 m ( 14 ft)
Length: 5 m(16.5 ft)
Height: 2.43 m(8ft)
Approximate Listening position From speakers: 3 m (9.8 ft)
Distance between speakers :2 .7m(8.9 ft) I have planned already where to keep them Is the room too small for them ?
I am attracted by the unique 2 Tweeter 2 Midrange configuration of M80s over M60s and money is not constraint
(By the way I saw the pictures of your set up and I am very much impressed)
