    Single sa x-18 ported box 33.35hz on music?

    Hey guys,

    Need a bit of help here as I searched all over and cannot find any info on this X-18 ported enclosure, size is not an issue since its going into a van.. I would like to keep it 'musical' but has some 'thump' when need be, daily driven across the midwest, weekly.. I ordered a single X-18 D2, will be running at 1ohm on my IA 20.1, roughly 1800 rms, wiring and extra power all taken cared of. I used the Torres Box Calculator and came up with some # and need to see if this is something you guys think will work or not..

    First the subs specs:

    X 18
    Fs : 20.5 Hz
    Qes : 0.57
    Qms : 5.61
    Qts : 0.52
    Le : 5.92 mH
    Sd : 1140 cm^2
    Vas : 237 L
    BL : 24.79 NA
    Mms : 470 g
    Cms : 128 uM/N
    Sens : 87.22 dB 1w/1m
    Wattage: 1250wRM

    Torres Box #'s I came up with:

    GROSS VOLUME: 6.80CF
    PORT VOLUME: 1.27FT
    PORT AREA PER CUBE: 15.32IN
    PORT AREA: 74.00IN
    NET VOLUME: 4.83FT
    PHYSICAL PORT LENGTH: 22.50
    TUNING: 33.35

    Basically, box is going to measure 40X18X20.. with one slot port.. So, question is, do you think the box is too big for 1800 rms??. If so, what size box should I use?. Any help from you guys would be great!!. Even a link if anyone knows of one.

    Well, maybe its new and no one knows yet???.. I know they are selling them like hot cakes so I can't imagine, there is not a person putting it into a box??.

    Personally I think the box would be good. Im putting my PSI PF2 18 in a 6.91 tuned at 32 for music.
