Taking these photos I am standing at the front wall looking towards the back of the room. You see the opening to the equipment room on the left, and then two large fixed glass windows (covered in orange paper), and then the glass breakfast nook (the exterior wall of which is covered in yellow paper) which extends five feet behind the windows on the left, and then the glass wall panels to the kitchen on the right.
I have been planning to put a drop down shade in the opening between the listening room and the equipment room; shades over the two large glass panels; a movable curtain to block the glass breakfast nook and a movable curtain covering most of the glass wall panels to the kitchen.
After speaking with David I think I am going to drop the idea of a shade in the opening between the listening room in the equipment room, and the idea of a movable curtain covering most of the glass wall of the kitchen. The glass wall of the kitchen will be retracted and open when I'm listening to music.
I think it makes sense to start out simpler. David recommends natural wood shutters or blinds. He believes that most fabrics have uneven frequency absorption characteristics. I would prefer vertical slats for decor reasons.
I think I am going to leave the top window uncovered; specify vertical wood slats in a color similar to natural walnut in the large lower window, and extend those slats to the right between the wall and the track of the kitchen glass wall panels.
In the first photo you can see the swing-out wall-mounted lights. Six lights are spaced every two feet and are located above where the equipment racks will be placed. Floor-standing MikeL lamps will be added later. I want that turntable lit up like an alien landing pad.
