when listening from behind the system, switch the front drivers in and out. You should hear a

When listening from the front, you should hear a strong increase in the LF range when connecting the
rear drivers.

8.5 Final Pre-Sound Check Check
•
Play a CD track (preferably generous and periodic in the LF content) on the SUB output, mono left,
mono right and then both sides:
•
both sides must sound strictly identical when listening at the center;
•
level must not decrease at the center when playing left and right simultaneously as opposed to one
side only.
•
Play the same CD track on the MAIN system, on the SUB system, then on both:
•
Inverting polarity on one of these outputs – MAIN or SUB - should always result in a massive
difference near the crossover point.
