2)lowpass filter slope selector switch - 12dB/oct or 24dB/oct. wat shud this be on?
3) Subsonic mode selector switch - off or 15Hz????
4)The input level (gain) - 0.1V-8V (my HU is 2.2V) so wat shud i have this set to??? |
Try this..... adjust the x-over point to approx 70-90hz, set the slope to 24db/octave and leave the subsonic filter off and set the gain to about 1 volt. (*unknown factor 6x9 speaker efficiency vs sub)
now, close the doors & window up. listen to a recording that has good subbass output around 25-45hz...... then flick on the 15hz filter and see if it improve the transient response without losing the very bottom of bass extension. (usually 15hz is not too bad if it has a 18-24db/octave roll off.)
and leave it on if it's an improvement.
