TWEETER ATTENUATION ADJUSTMENT
When setting the attenuation of your tweeter, you are going to want to adjust this level by the dis-
tance from tweeter to listener as well as personal preferences.  The attenuation has fi ve levels that 
range from 0dB to –6dB. Generally, this would be set up with 0dB being further away, and –6dB being 
closer, to the listener’s ear.  If you have the attenuation set at 0dB and the speakers seem too bright, 
adjust the jumper downward until it matches your personal taste. If the speakers seem too dim or 
quiet, adjust the tweeter upward. 
Note: The tweeter adjustments will also dramatically affect the balance between your tweeter and 
the 0, 30, and 60 degree setting of your midrange. After setting the tweeter to a comfortable level, 
you may need to readjust your midrange off-axis adjustment to achieve the optimum balance.
THREE LEVEL OFF-AXIS ADJUSTMENT
MTX designed the TXC components to compensate for undesirable factory mounting locations within 
the vehicles by including a three level on-/off-axis adjustment feature. Since you cannot move the 
factory speaker mounting locations within the vehicle, these adjustments will help to deliver sound 
that is clear, deep, and positioned like it is coming from directly in front of you.  The music will have 
a sense of depth where it sounds like it is not confi ned by the windshield but rather coming from the 
road in front of you. 
There are three settings on the crossover for Off-axis adjustments- 0˚, 30˚, and 60˚. These positions 
will compensate for the speaker placement and will use your vehicle’s unique environment to create 
the best sounding system possible. 
Note: For applications greater than 60˚, the 60˚ position setting is recommended
Once the speakers are installed in their fi nal locations, do the “sit in the seat and close your eyes 
test.” The vocals should be jump out at you, be cleanly defi ned, and move from side to side while the 
instrumentation should be full and distinct layers. If you don’t hear your music in this fashion, select 
a different jumper position and repeat the “sit in the seat and close your eyes test” (The jumper 
settings listed below are our recommended starting points). Take time to listen to the components in 
each of the jumper settings in detail to determine which sound is best for your application.
