  1. Sorry, forgot to convert the values ​​here . The manufacturer is tuned above 40Hz and inappropriate for you

    Your small car and thus the max SPL to dodge

    whopping gross: 5,728 cu.ft

    Port: 2x diameter 3,93700787401575in x length 11,8110236220472in

    Box tuned 29hz,

    or

    slot port : length : 13,7795275590551in x height 1,5748031496063in x depth 13,7795275590551in

    box tuning 27,2hz

    box tested Citroen Saxo and Toyota Yaris!

    simulation and measurement corresponds

    good luck gally

    umm....what?

    i dont do this build for SPL....its more like sql it for my own musical taste...

  2. So, today i pourchaused a Ground Zero Hydrogen 38X, or its a 15˝ dual 2ohm subwoofer with a FS of 19.3hz...so this project is for the lows...mostly

    my space dimension

    55cm/21.7inch length or depth-

    114cm/44,8inch width--

    53cm/20,9inch height---

    im sorrsy but im trying to type from my em...sort of a tablet computer and is a little difficult

    and the frequency i would like to be from 29-32hz...

  3. Well here is a suggestion (for the car in the sig):

    Enclosure Specifications:

    Fb = 35.5 Hz

    Vb = 3.15 ft^3

    External Height = 16 in

    External Width = 40 in

    External Depth = 16 in

    Port Width = 3 3/4 in

    Cut Sheet List:

    * All Dimensions in Inches.

    * Wood Thickness is 3/4 for all Parts.

    External Enclosure Parts:

    2 x Top & Bottom (3 parts) = 40 x 16

    Left & Right Sides =

    Side 1 = 14 1/2 x 13 3/4

    Side 2 = 15 1/4 x 13 3/4

    Front = 35 1/2 x 13 3/4

    Back = 40 x 13 3/4

    L Port Internal Assembly Parts:

    Front to Back = 10 3/4 x 13 3/4

    Extension = 11 x 13 3/4

    If you want something different let me know

    thank you sir!!!

    thats exactly the design i was looking for...

  4. they are very tricky subs and need no break in time so i would say you need to try a differnt design

    had some amplifier settings off the mark...so now they sounds pretty good but the lows dont get so much attention...i mean....i can feel 27hz so strong but when it comes to 26hz....nothing....tested with test tones and music....26hz and bellow there is nothing...subs move like crazy and no sound...just air

    could it be gain matching? i have seen this before when the amp was not getting enough signal

    yeah...gain which was set after that and the subsonic filter...

  6. I usually have the SSF set 3 below tuning. It's not a wall, so its not like you're not playing anything below that

    so today i installed my fifth sistem....2 pioneers 3002 D4 on 32hz...my subsonic is set at 24 or 25hz, and it moves a LOT of air....but no sound at all...and the subs moves like crazy....
