This control helps to align the phase shift of a subwoofer for a smooth blending, without canceling 

the bass from other speakers or subwoofer(s). The Phase is continuously adjustable from 0 to 180 

degrees.

Sub Sonic Filter Adjustment

 

This filter avoids the reproduction of inaudible low frequencies which could damage the 

subwoofer(s). The Sub Sonic filter is fully adjustable between 20Hz and 50Hz. Frequencies below 

20 Hz are considered inaudible to the human ear. 

 

HOW TO SET UP 

1.    A SINGLE VOICE COIL SUBWOOFER SPEAKER (XT 3.5KW, XT 5.0KW) 

 
 
 
 
 
 
 

Don’t connect two 1 Ohm speaker simultaneously
