    Double check box specs

    This is my first box attempt and to be honest, want to make it kinda simple but still functional.

    First off i have 2 - 12" PG Rsdc 122 (displacment is .13 for each so .26 total)

    Second set of info i got from the manufacture it is recommend 2.5 cubic ft per sub for more SQ while they say ~ 1 cubic ft for SPL. I started a thread a while back trying to find out this info and just recently found a pdf version of the manual.

    I used a box program and these are what i came up with so far. I want a simple slotted port box, around 4 cubft after displacemnt. Subs up, port firing to driver side. 3/4 mdf will be used

    (all outer dimentions)
    Height: 13in
    Width: 30 in
    Depth: 28 in

    Port specs
    (all inner dimensions)
    height: 11.5
    width: 4.5
    length: 18.25


    With that i got gross of 5.03 cubft, .74cubft port, physical port length to be 17.5 and 51.75cuin port area( 12.8 per cubic foot)

    Leaving me a net of 4 cubic feet tuned to 36 hz.

    Does this sound correct? Also what should my cutouts be for my top, bottom, sides, etc because the program i had didnt let me input where the port will be so it didnt factor that in on the sheets.

    Thanks in advance, also if u have any suggestions on which type of glue/screws i should use id love to know.

    What program did you use? Expo's box calc? I'm getting the same results you did, or at least, **** near them.

    4.24 ft^3 @ 36.87 Hz
