Specifications Are Subject To Change Without Notice

Phase  Control:

 The  phase  control  is  a  switch  located  on  the  panel  with  the 

electrical connections. This switch will reverse the phase of BP112's output with 
respect to its input. When installing BP112 with an existing factory or aftermarket 
system, depending on BP112’s location in the vehicle and the distance between 
it and the other speakers in the car, reversing the phase (by moving the phase 
switch) may produce a discernable increase or decrease in the amount of upper 
bass  reproduced.  Although  the  position  that  yields  the  most  upper  bass  is 
technically correct, you may choose the position that better suits your taste.

Crossover: 

The  crossover  control  adjusts  the  amount  of  high-frequency 

information present in BP112’s output.

Power LED: 

The power LED will glow red to indicate that BP112 is operational.

Thermal Protection LEDs:

 The Thermal/Protection LEDs will glow green when 

the  protection  circuit  has  determined  that  the  woofer  has  reached  maximum 
excursion and power. BP112’s woofer has been modified to provide maximum 
performance,  monitor  the  Thermal  LED  while  you  are  tuning  BP112.  When 
BP112 is properly tuned the servo LED should light momentarily during high-
level  bass transients. Avoid adjustments  that cause the LED to remain  lit for 
extended periods.
