The HIGHPASS filtering setting (HPF) - on the respective control - of
the satellite channels will also take away unnecessary mechanical and
electrical 'strain' from coaxial speakers or component speaker systems
(compos), as such speakers are not designed to reproduce powerful
bass signals in the first place. Depending on the actual cone surface
area, voice-coil diameter and the rated power handling of the 'satellites'
it is recomenended to set the hiphpass cross-over / cut-in frequency
between 40 and 240 Hz.
If the satellite highpass frequency is set too low, the mid-bass repro-
duction will be increased, but at the same time the power-handling
capacity of the satellites will decrease. If the highpass frequency is set
too high, the mid-bass reproduction will become 'thinner' while the
power-handling capacity of the satellites will increase.

Satellite . r ule . 1 . The better sounding satellite system should
always be installed in the front of the vehicle.
Satellite . r ule . 2 Based on identical speaker diameters and
comparable engineering quality of the front
and rear satellites, the crossover / cut-in
frequency of the front satellites should
usually be set lower than the highpass
frequency of the rear satellites.
The .(LOWPASS) .crossover .frequency .for .the .subwoofer .should
usually be selected between . 5 0 . a nd . 9 0 . H z. Adjust the LOWPASS cut-
off control in such a way that the bass reproduction will be precise and
rich, while still delivering a good and solid low-end bass.
Subwoofer .
Generally, setting the LPF lowpass cut-off
frequency too low will result In a weak and
uncontoured bass response.
Setting the LPF control too high tends to give
the subwoofer a 'booming' sound.
