Alex,
My listening room is about 11.6 X11.6 located on the second floor of a one and half story house so the second floor ceilings slope to match the roof line outside.

The speakers are in the corners about five inches from the side walls under one of the sloped ceilings and the backs of the speakers are parallel to the wall they are against.
I found that toeing them in resulted in way too much direct higher frequency info from the horns in the small room.

The room contains a small sofa opposite the speakers, curtains on a double window unit, (side by side) a rug covering 70% of the floor and misc stuff like LP's and end tables on each side of the sofa with lamps on them.

The only problem I am aware of is with source material with lots of upper midrange information at higher listening levels like Placido Domingo or Maynard Ferguson recorded a bit on the hot sizzly side.

I think there the room is just too small and too live at higher volumes yet Joan Sutherland sounds great at high levels so it's recording related too plus I am using 3-4db of treble boost at 20KHZ to compensate for the 802G falling response after around 13KHZ.

I hear no problems with the bass and I'm using about 3db of bass boost under 100HZ.
It could be that I'd like the 19's more in a larger room but they sound so good now I have no real complaints.
