OPERATING INSTRUCTIONS
Congratulations on your purchase of this AXTON enclosure sub-
woofer system. Please read and follow the provided installation
and operating instructions carefully, to benefit from the max. sound
quality and performance this component is capable of.
CONNECTION & INSTALLATION
Your trunk box subwoofer is designed to be placed in the trunk
compartment of your car, where it uses the boundary effect for linear
output and good bass extension. The terminal binding posts allow
quick and easy installation or removal of the trunk box – should this
be necessary from time to time. Ideally, the box should be placed
with the angled backside against the rear seats or against the front
dividing wall of the trunk compartment.
Connect the speaker wire coming from the sub-amplifier to the
terminal binding post of the subwoofer system. The best connec-
tion polarity of the speaker wire connected to your subwoofer will
be adjusted in the set up process described in the next chapter.
AMPLIFIER ADJUSTMENTS
LOW PASS FILTER
Your AXTON trunk box subwoofer needs a low-pass filtered signal for
optimum results. The low pass filter slope steepness of the electronic
crossover should be at least 12 dB/oct.. Make sure that the low-
pass function of the amplifier channel(s) driving the subwoofer is
activated! Use the HPF (High Pass Filter) function of your amplifier
to cut of the low frequencies for the other channels driving the main
speakers and tweeters.
CROSSOVER FREQUENCY
A recommended starting point for the low pass cut-off frequency
is around 70 to 100 Hz and must be played by ear, i.e. is found
empirically by adjusting the frequency up and down in small steps
until the sonic result is pleasing.

BANDPASS ENCLOSURE
SUBWOOFER
The final crossover frequency and input gain adjustments on the
sub-amp should only be attempted after all tone controls such as
„treble", „bass" and „loudness" have been set back to their neutral/
zero position.
AMPLIFIER INPUT GAIN
Before you proceed, please close the input gain adjustment. Please
refer also to the manual of the amplifier. Now with the music playing
at a 3/4 to 4/5 level, open the input gain of the channel(s) driving
your AXTON subwoofer, until the amount of bass is balanced with
the remaining spectrum of the music.
ACOUSTICAL IN-PHASE CONNECTION
The acoustical „in-phase" connection of your subwoofer is critical
for best sonic results.
In-phase connection means that the corresponding acoustical
outputs of the satellite speakers in the front doors are in phase with
the output of your subwoofer, to sum up properly at the cross-over
frequency point. Out of phase connection means, the acoustical
output will cancel itself at the crossover frequency. Reversing the
polarity of the speaker cables connected to the terminal of your
subwoofer reveals the correct connection, since "in-phase" connec-
tion will give you a stronger and fuller reproduction of bass content
and the music that is played back on your sound system. Once the
correct electrical polarity is found, you need to adjust the input gain
once more, and fine tune the crossover frequency as the last step.
In general, selecting a crossover frequency too low will yield to
unprecise and infra-bass heavy sound without punch, whilst setting
the corresponding lowpass x-over point to high will render a hard
and droning sound reproduction.
