This picture shows not actual measured curves. It is only intended to be used as an illustration on the different acoustic 

characteristics in the lower frequencies. 

Room Tuning - 
Mechanical 

adjustment of the 
boundary frequency 

 

 

 

 

  

By using the supplied bass plugs in the bass reflex
gates, you can alter the lower boundary frequency

on XTZ 99 W12. 
This makes it possible to alter the sonic 

characteristics of the woofer. The picture below
shows 3 basic settings. 

 
This is a ground setting for the subwoofer then you

use the DSP functions to adjust the characteristics

perfectly. 
 

With 1 or 2 open reflex gates(bass-reflex) will 
increase the efficiency so it can handle more sound

pressure than with 2 closed reflex gates(closed-box) 
 

1st mode - no plugs in the reflex gates  

No plugs in the gates will provide a "quick" bass
character especially suitable for larger rooms where

the lower frequencies often are amplified by the
room itself. 

 
2nd mode - 2 bass plugs in the reflex gates 

 

This will provide a neutral, even and controled bass 
setting(Closed box) 

 
3rd mode - 1 plug in the reflex gate 

 
All plugs in the gates will provide a "deep" bass

suitable for smaller rooms. 

 

 

 

Since the sonic characteristics depends on 
the room a whole range of external 
factors, there exists no "standard" setting 
for a neutral representation. 
 
Room tuning will also have influence on 
the efficiency you will have to adjust the 
volume, frequency and High Pass in the 
room tuning modes.  
"Quick" bass explained: 
By this we mean a bass with less deep bass 
information. This might also be called 
"hard", "attack", "tight", "punchy" etc.
