DSP 

 

  

The built-in DSP module works is equipped with 

24-bit/96-kHz AD/DA converters and the best 
software on the market today allowing you perfect 

adaptation of the subwoofer to the room 
characteristic and adjustment of the sound

character, always keeping best possible quality of 
sound.  

 

To provide the highest sound quality the DSP runs 
advanced low-noise filter algorithms with 32-bit 

calculation precision. The software consists of
parametric and graphic equalizer, phase correction,

low-cut and high-cut filters, and delay. 
 

There are many "cheap" equalizers on the market, 

but the most are not good enough to maintain the
high sound quality  for low frequencies because of 

using not appropriate algorithms. The DSP 
software used in the subwoofer has been developed 

by a world leading German company with 25-years 
tradition in professional audio.   

Many years of development is behind the software

we use in 99 W12 DSP. 

 

   

 

 

The cabinet 

 

 

The cabinet is made of 25mm MDF with 3 stays

which makes the box stable  and without 
resonances. 

 
The surface is varnished giving a proper look and 

air sealed box.
