Steve , are those GIK panels in the window, and are they absorbers?
Did they contribute to the image focus or is that effect more from first reflection correction?

They are the GIK 242 Absorbing panels you can see behind the speakers, against the sliding patio doors. They do contribute to image focus. The pictures below show the same GIK 242 panels used on the side walls at the first and second reflection points. The panel that can be seen on the window sill behind the listening position is a GIK Monster Bass Trap and is considerably thicker than the 242 panels. The DaaD tubes have absorbtion faces as well as diffusion. I have found that using diffussion at the front corners and between the speakers, facing the listening position enhances the soundstage. The large DaaD4's in the corners behind the listening position have their diffusing faces pointing outwards towards the side walls.
The overall effect, arrived at through experimentation, in what I would describe as a 'difficult' room to tune (24' X 11' X 8') is rock-solid imagery within the soundstage. The music is nicely layered, behind the plane of the speakers and there is tremendous depth and clarity to the images. Particularly listening in a darkened room, vocals can be clearly delineated from the position of the drums, double bass, piano etc. and adds to the realism of the listening experience
