I have an X12, 4ohm with BP power option, in a 1cu ft box after displacement, running on 350 watts. I need to know about what frequencies to set to LPF and subsonic adjustments on my Mono amp to best meet the specs of the sub. My subsonic will adust from OFF to 50Hz and the LPF adjusts from 40Hz to 220Hz

Thanks

Steve

I assume your box is sealed since it's 1 ft3? If that's the case then leave the subsonic filter at 0. For the low pass, put it at approximately 80 hz (it's really personal preference so just play with it a little bit to get it how you like it. 80 hz is just a general starting point).

If it is a sealed box you should not need a subsonic filter.

Yes it is a sealed box.
