SETUP PROCEDURES

DELAY SETTING
The DELAY control is used to properly blend the main speakers with the 
subwoofer through the crossover region. The goal is to adjust the DELAY 
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 DELAY 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 DELAY setting. Set the SPL meter 
in your key seating position and play several “bassy” music tracks. While 
the music is playing SLOWLY turn the DELAY control and watch the SPL 
meter (you may need a friend for this). The highest reading is usually 
indicative of the best DELAY 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 DELAY control. When the bass 
sounds loudest to you....you have the correct DELAY 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 (150HZ/BYPASS) and your 
receiver or processor performs all of the proper fi ltering. Please contact 
us if you need help adjusting the CROSSOVER control. 

ROOM SIZE SETTING
The ROOM SIZE control is an adjustable bass shelf attenuation fi lter. 
The large setting will provide zero attenuation to the native frequency 
response of the subwoofer. The small setting will provide the maximum 
amount of available attenuation. This control is typically set to the user’s 
preference for deep bass and their room environment. In many sce-
narios the more the control is oriented to SMALL the “tighter” the bass 
may sound. Please experiment with this control as time allows as every 
room is a little diff erent. Please contact us if you need help adjusting the 
ROOM SIZE control.
