    Help selecting a encloser for my new sub!!

    I just got a Diamond Audio HP12 sub. I'm looking for the right enclosure for it. I know that buying/building a custom box would be perferable but I lack money tools and time to do it.

    I have been trying to find a vented box that will fit in my trunk and match the subs requirements.
    Here are the requirements for the sub
    Air space (vb) = 1.75
    fb/f3 (Hz) - 35/29
    Port/s (in)(dia X length) = 4 X 16
    pe (W) = 1000
    Mounting depth = 8
    Displacment = 0.15 ft3

    The box specifications are
    12 Single Labyrinth Vented Subwoofer Box 1.86 Cu Ft Air Space
    Height: 14 3/8"
    Width: 20 1/8"
    Depth: 16 3/8
    1.86 Cu Ft Air Space per woofer
    Tuned at: 36 Hz
    Cut out diameter: 11 1/16"
    Mounting depth: 11 7/8"
    Holds one 12" woofer
    Material: Premium USA MDF
    Material Thickness: 3/4"

    If the vent frequence is off by 1 hz, what effect will it have? Does anyone have an opinion on Obcon labyrinth box (good or bad)? Is this going to be a good match?

    The area of my trunk is about 23 inches wide, 14 inch tall and has a depth of 16 inches. So I want to stay in that size range.

    That box isn't too bad for a prefab. But why not go custom? You'll get things like 1 1/2" front baffles, flush mounting, etc. I'd also go about 2.5 cubes tuned to around 30 or so. But that's just me. I prefer larger boxes that are tuned low and manufacturer's specs are usually too small imo.
