When properly set up, very little sound should appear to come directly from the speaker. Instead, the sound stage should extend far beyond the left and right edge of the loudspeakers and there should be tremendous front to back depth. When the recording is
A simple rule of thumb to follow is that focus will be achieved by placing the speakers closer together or
2.3Phase Control
We suggested in the beginning of this section to set the phase to 0, 45 or 75 degrees. Now that you have roughed the system in, you may want to experiment with different phase settings.
Using the remote control you can adjust the woofer's phase angle up or down in
The changes are subtle and they usually affect the imaging and soundstage. Listen carefully to the positioning (in acoustic space), of the orchestral players as you change the phase control. You may notice small shifts in their apparent relationship to the other members of the orchestra. Do not expect them to actually move. Expect minute changes in the soundstage, the apparent width of the stage, your ability to distinguish individual players etc.
If you are using the output from the preamplifier to drive the servo- bass amplifier, the phase setting you need will depend on the relative difference between the input phase and the output phase of the power amplifier used. In extreme cases, where the power amplifier inverts phase, the phase setting you use may have to be 135 degrees or more.
Experiment with rock and blues recording (even if you only listen to classical music). If the phase is correct, your foot will naturally tap in time to the music. If the phase is out, you may think that the drummer is having difficulty coordinating his cymbal work with his kick drum.
