Electro-acoustic Tuning
After you finish installing the enclosure in your vehicle, it is recommended to spend some time
to tune the system and its amplifiers. Remember that a small power amplifier driven into full
distortion can damage a speaker. On the contrary, a very powerful amplifier with a linear
operation rarely causes system failures.
Reflex Tuning
Before completely finishing your reflex enclosure, we recommend that you test its response
in your vehicle first, as this is the only way to be sure you achieve the best sound according
to your preference:
Do not use loudness controls or equalizers at low frequencies.
Adjust the amplifier gain control to make use of all
the amplifiers undistorted power.
If available, use the subsonic filter, setting
the cut-off frequency around 25 Hz.
Set the cut-off frequency between 45 and 120 Hz
according to the type of configuration used.
Vary the tuning frequency by changing the port length
or the quantity of damping material inside the box.
If you shorten the port or reduce the quantity of damping
material, the tuning frequency increases and the bass will be
harder and lean.
A longer port or more damping material will lower the tuning
frequency creating a less defined but deeper bass.
Experiment with the positioning
of the enclosure inside your vehicle,
changing the output direction of the
subwoofer box and the tuning port.
Test both ways and choose what you prefer.
