PMC’s 

twenty  

active subwoofer features DSP-based user-equalisation options. These comprise an 

adjustable low-pass filter to determine the frequency range over which the subwoofer operates, 
with an adjustable slope which allows perfect integration with the low-frequency response of the 
satellite speakers.  

The low-pass filter can be switched off, or configured with a slope of 6, 12, or 18dB per octave, and 
with turnover frequencies of 50, 80,120,150, or 200Hz, as illustrated in this diagram.
 
 
 
 
 
 
 
 
 
 

When using the 

twenty 

active subwoofer with any other model from the 

twenty 

series range, we 

recommend starting with a low-pass filter setting of 80Hz. However, you may adjust this setting as 
room conditions and personal preferences dictate (see pages 19 & 20 for initial set ups with 

twenty

 

series products).
