  23. Tline Tuning

    in Subwoofers / Enclosures

    Posted

    Using math on the first page of the T-line thread you should have something like this:

    ( 1130 / freq ) / ¼ = ¼ wave length and ( Cone Area / 2 ) = ( X )² x 3.14 = X in²

    SO....

    ( 1130 / 30.76 ) / ¼ = 12.245ft and ( 11 / 2 ) = (5.5)² x 3.14 = 94.985n² (90in² rounded)

    SO you need to have 90n² of constant port with the port length totaling 12.245ft.

    Of course all that math is just for one 12. If you can figure out the math and squeeze two 12's in the same port (which I doubt you can) Then you'll need

    atleast 24in ~25in height internally and if you go with 25in tall then your width can only be 3.6. Because 25 x 3.6 = 90n² and 3.6 won't cut it unless your running some really shallow subs.

    Not sure is if you can boost the 90n² to 180n² and run both subs in the same chamber. Might wanna ask forever bumpin about that.

    But if you could then you're golden because 25in x 7.2in = 180n² and 7.2 is plenty of mounting room.

    SO... you're port would need to be 25in tall x 7.2in wide x 12.245ft long.

    Confirm that info tho.
