    just seeing if i can get remotely close..

    i know you guys hate this but i gotta know how close (if at all) i came...

    after displacement internal vol. = 4.051 cubes
    15.5 x 1.824" port , 10.853" long. Port area of 28.27"^2

    i was attempting to get a tuning of 35hz, i know numbers arnt exact but is it close? because i got plans from diamond (this is for a 15" cm3) in which the box is 22 x 17.5 x 21.5, and a port with dimensions of 3 x 16 x 39. And that was just so much different than what i came up with.

    Id like to use my design if its close, as i think itd get slightly louder.

    your calculations are close, but its gonna be hard to cut your mdf to 10.853
    I would round up and redo the math to get the same tuning

    the box dimensions you got from diamond would be a box with a volume 2.4 after displacements tuned to about 28 hz

    Re: just seeing if i can get remotely close..

    if i redo my design should i use more port area, since theirs was pretty high on the design i got from them

    thanks for your help btw

    //edit: diamond tech emailed me and said they recommend 2 4inch round ports, 10 inches long. anyone care to explain what that would amount to in terms of sq inches for a rectangular port?
