SETUP PROCEDURES
PHASE SETTING
The PHASE control is used to properly blend the main speakers with
the subwoofer through the crossover region. The goal is to adjust the
PHASE control so the subwoofer driver moves in unison with the main
speaker drivers through the crossover region. Think of it as a “timing
delay” for the subwoofer driver.
When experimenting with the phase setting the idea is to get the output
from the subwoofer perfectly “in time” with the output from the rest of
your speakers, primarily the left and right front speakers. If you have an
SPL meter it is easy to optimize the phase setting. Set the SPL meter in
your key seating position and play several “bassy” music tracks. While
the music is playing SLOWLY turn the phase control and watch the SPL
meter (you may need a friend for this). The highest reading is usually
indicative of the best phase setting. If you don’t have an SPL meter, you
can repeat the above process but simply use your ears to determine
when the bass seems loudest. In this scenario, sit in your key seating po-
sition and have a friend SLOWLY turn the phase control. When the bass
sounds loudest to you....you have the best phase setting!
CROSSOVER SETTING
The CROSSOVER control is an adjustable low pass fi lter. Output at
frequencies above the crossover setting are minimized. This control is
typically set to the fully clockwise position (LFE) and your receiver or pro-
cessor performs all of the proper fi ltering. Please contact us if you need
help adjusting the CROSSOVER control.
