Focal FP 1.800 - Manual (Page 19)

In order to optimise the overlap of frequency ranges reproduced by the subwoofer and the coaxial or
2-way kits, we advise you to adjust the frequency of the HI PASS filter or that of the LO PASS with an RTA
(real-time analyser). Another possibility is to refer to the packaging of your kit or its user’s manual. In the case
of a Focal kit, the measurements supplied as frequency response take into account the installation of the kit
inside a vehicle.
Tuning the FP 1.800 amplifier for SPL contests:
NOTE:
The following adjustments do not correspond to a “musical” use of the amplifier. What is sought here is the
maximum sound pressure level without damaging the subwoofer/s.
The use of the FP 1.800 amplifier during SPL contests is an additional asset. The various adjustments available
enable you to optimize the amplification for use in SPL contests. Tune the SUBSONIC filter to 50Hz. Position the
BASS BOOST level at 12dB, then tune the BASS BOOST frequency to 60Hz. Adjust the LO PASS to 80Hz
