I don't know what "against the interests of the room" means. Does this mean placing planar dipole speakers against the front wall when they're supposed to be well into the room?
Does this mean placing speakers against the short wall when they are designed to be in front of the long wall?
But we can add this to our compiled list of Roman pronouncements which sound important, but which are substantially incorrect.
“Against” does not mean that, it means the speakers should play the room from neutral zone. Finding neutral zone (dpols) need many hours of speaker placement. It is very hard and some guys like styrling or Jim Smith can help.
You can read the sumiko method of speaker placement.
my experience shows Romy is right ,
Two times with two different systems I have experienced the perfect speaker position.
Ron , I agree Kedar a well setup small speaker will outperform wilson XVX easily.
I listened to small Living Voice 2way ($10k) cone speaker in small room, the source was Analog Microseiki 5000 , the speaker position was very good, the amplifier speaker matching was good, AC quality was good, the sound was much better than all wilson XVX in three rooms of munich
