Connections
It is essential that correct polarity be observed with subwoofers. Positive is marked in red,
negative in black.
Wiring
The quality and gauge of wire used will have a strong effect on the quality of sound. Focal
Audiomobile recommend a minimum specification of 2.5mm
2
oxygen free copper (OFC) wire
for subwoofers. Ask your dealer for advice on your specific installation. We recommend the use
of Focal FC 300 and FC 500 cables.
Adjusting the cut-off frequency
The ideal cut-off frequency is usually between 60 and 100 Hz. Optimum adjustment can only
be achieved after listening and/or measuring.
Recommended power
Focal Audiomobile subwoofers have high power handling characteristics. It is therefore
important to choose an amplifier powerful enough to drive them properly. An amplifier that is
too small will distort quickly, limiting the level and quality of the sound and eventually causing
damages to the loudspeakers.
Due to constant technological advances, Focal reserves its right to modify specifications without notice. Images may not conform exactly to specific product.
