Some random quotes for your specific needs from Dunlavy's old web site: "Loudspeakers should be located along a wall facing the shortest dimension of the room for most accurate reproduction of bass". "It is usually best if the distance of a loudspeaker from the side-wall does not equal the distance to the back wall." "For a typical room of average size, e.g. 8 feet high, 13 feet wide, and 20 feet long and a listening distance of from 8 to 12 feet, a good starting distance between the loudspeakers and the backwall would be approximately 1 1/2 to 2 feet ands a distance to the side walls of about 3 to 4 feet.""After listening for several minutes of music at these distances, either shorten or lengthen the distance to the back walls by about 6 inches and determine whether of not the change made an improvement in the overall spectral balance. Patient expermintation with different distances will usually be necessay before optimum distances to the back and side walls are discovered.""If, in the "AVERAGE ROOM"* described above, the listening position is located against a long wall (20 feet) at its center (10 feet from each end) and the loudspeakers are located along the opposite long wall, about 3 feet from the back wall and 4 feet from the side-walls, the angle subtended from the listener is about 65 degrees and the listening position within an "average room" represents a good staring point." "The angle subtended by the speakers from the listening postion should exceed about 60 degrees (the distance from the listening position to each speaker should be less than the distance seperating the speakers).""Research accomplished by DAL has shown that a 4 foot wide by 7 foot high sheet of 3 to 4 inch thick acoustical foam placed on the wall immediatley behind the listener can often turn a problem-room in to an audio pleasure-palace.""A thick sound-absorbing drape (preferably with a high percentge of wool) between the listener and the back-wall will further mitigate problems from developing at the low-end of the sound spectrum. (A low-cost alternative is to use a 3 to 4 inch thickness of sound-absorbing polyester foam, perhaps 4 X 6 feet affixed to the wall behind an attractive drape, preferably one containing at least some natural wool (which will help absorb mid and high frequencies).

While there may appear to be some contradictions, I think you get the idea that these suggestions may be a good starting point and you may need to fiddle about with a few inches here and there. BTW, I have had sucess with these recommedations with Dunlavy SCIV's. Good luck!
