Dunlavy question for Steven Stone

 Hello,
 
Dunlavy speakers, whether they are SC1's or SCVI's, need to be ten feet from the speaker to the listener's ears for ideal phase coherence. That is the distance John D. used for calibration and testing. I toe in my SC VI's so I can't see either side from listening position.
 
As for distance from side wall and back wall, if you are running them full-range without a subwoofer I suggest several things:
 
1. Move then as far into the room as is ergonomically possible for initial set up and then gradually move them toward the side walls until that point where the room becomes overly-energized by bass frequencies - then move them farther away from the side and back walls to reduce this effect.
2. Do not set up the speakers so they are perfectly equidistant from the side walls i.e perfectly symmetrical in the room. Skew them at least 6" so the primary listening position is NOT dead center in relation to the side walls. Mine are 1' off center. This will reduce center point room node interactions at your listening position.
3. Use a test disk with both frequency sweeps and set point tones combined with a sound pressure meter to make sure there are no serious peaks or dips in the frequency response.
4. use something on the floor to absorb the floor bounce (thick rugs work, but an ASC half-round tube trap is even better). Also use absorbers for the first side reflections. 
I have included some photos of my set-up. Notice the tube trap is under the long oriental on the floor. Tube traps are also beside the screen to absorb sound that would otherwise reflect off the screen and affect imaging.
