    Icon32 (setting) lpf, subsonic filter, and tuning. ? . ? .

    I see alot of people post to turn this off(subsonic filter) . I have a pa lt980/2 and it turns up and down but not off what should I set it at? I have 2 atlas12's ported 2ft^3 each at 32hz also where should my setting for the lpf be set I have it turned to 30hz same as the subsonic filter at 30hz is this bad?
    also does anyone know a good port tuning for the atlas 12's their website only shows a sealed box.or would I be better off going to a smaller sealed box for the subs? rather than the 2ft^3 ported box I have them in now if the ported is ok I just need to know what hz. to port em at.

    ok I was told to set the low pass at 80~100hz and the sub sonic filter to 25~30hz I will try that and see what happens now .. .

    I made a box for an atlas 12" that was 4cubes gross, 2.7 of sub airspace, tuned to 27hz. the sub sounded phenomenal. granted i added a couple of port tricks to the box but it sounded better than really, any 12 ive ever heard under 400 bucks.



    i drive a honda element.

    -Eclipse AVN h/u
    -custom fiberglass doorpods
    -CDT 7.2usx comps
    -mmatts SQ####? amp (200x2wrms underrated)
    -"custom" TC9/XXX 15"
    -Cadence zrs-10

    and lots and lots of bjork.

    just a rounded out baffle maze, and a few other things.
    mostly little nuances borrowed from smaller horn designs

    Something not worth the time learning how to do, imo. Ported box would sound just great. I say HPF at 10hz...LPF at 80-100hz (whichever you want)



    Take off every 'sig.
