    Please help guys

    Hi guys i own a clarion pxw1552 DVC, 15",each coil is 4ohms, total power of 750rms, 1500 max power.
    those are the specs:

    Fs=23.28Hz
    Qms=5.927
    Vas in(L)=193.07
    Qes=0.6018
    Qts=0.546
    Vd=0.21ft^3
    Xmax=12.5mm
    .
    .
    .

    the supplier catalogue is saying that a vented box should have a net Vb=3.5ft^3 and a Vent dimension of: 4" ID and 7" long.
    Is it true?? isnt it a very small enclosure for that 15" sub?
    Thx a lot

    Re: Please help guys

    Hi, can u please tell me if my port dimension will be OK?

    the supplier catalogue is saying that a vented box should have a net Vb=3.5ft^3 and a Vent dimension of: 4" ID and 7" long, port area is OK?

    I used online calculators and found out that with such port dimensions=> my tuning freq is around 30Hz, but the calculators suggested that the minimum port diameter for the 30Hz tuning freq must be 7 inches. is it true? so i will have port noise....? thx

    WinISD says 4x7.6 for 30hz so I would say that should be fine.
    Just round all of the port edges to keep from having port noise.
