The electronics for the system are contained in a hall closet located behind the speaker wall. The speaker cable runs through the front wall, into the living room, and power to the closet is supplied by the two power conditioners which are plugged into a single outlet in a spare bedroom (then ran through the wall into the closet). The room is approx. 18' x 24' x 8' (1/3 of which is the dining and kitchen area). The floors are plaster/carpet/cotten rugs and the room contains three walls of books. The rest of the wall/door space is covered with (mainly) paintings on canvas. Lots of clutter, cats, et cetera.
