N°5 and N°6 Crossblock settings
N°5/N°6 Crossblock is an exclusive high technology crossover offering 4480 different filtering combinations to adapt kit's characteristics to car's environment and
to your own tastes.
We advise you to refer to the Quality Control Certificate provided with each kit in order to know the reference setting (fig. 1).
This setting corresponds to an optimized linearity obtained ac-cording to normalized measuring conditions (see file for more infor-mations) and is a good base
to refer to before begining settings. The response curve may change according to vehicle acoustic, speakers location, woofer / tweeter distance and speakers
orientation. An adapted Crossblock setting will allow to have a flat response curve. We advise you to use a measure equipment (RTA) for a fine setting. We advise
you to note the different settings in order to refer to them as often as you need.
S1 setting (Low-pass)
This setting changes the low-pass frequency value (12dB/octave). "1" refers to the higher value and "10" refers to the lower one (fig. 2).
S2 setting (Q factor)
This setting allows to boost midrange. It aims at correcting medium when the woofer is out of the listening axis, low in the door for example, midrange's losses may
occur. "8" refers to a linear response whereas "1" refers to maximum midrange's boost (fig. 3).
S3 setting (Hi-pass)
This setting changes the hi-pass frequency value (12 dB/octave). Seven settings are available. "1" refers to the higher value whereas "7" refers to the lower one
(fig. 4).
S4 setting (Level)
It refers to tweeter level setting. Each value change level around 1dB per step. "8" refers to minimum boost whereas "1" refers to maximum boost (fig. 5).
