    Old School Oz Audio 250h 10" subs

    Ok I am looking for box specs for these old school SQ subwoofers. I have the Parameters but I cannot seem to find anymore information on if they do better vented or sealed.

    Spec's

    Qts: 0.40
    Vas: 250.0 l
    Fs: 17.50 Hz
    Re: 2.97 ohm
    Le: 1.45
    Xmax: 0.011 m
    Z: 4.00 ohm
    Qms: 8.35
    Qes: 0.41
    SPL: 90.00 dB
    Pe: 0.0 W
    BL: 8.90
    dia: 0.305 m
    Sd: 0.047 m^2

    I downloaded WinISD.044 Beta from http://www.linearteam.dk/ I'll admit I am not a spec's junkie and I am lost on what I am looking at here..



    If anyone has any idea about these subs or can point me in the right direction on how to get enclosure information (Oz Audios website is pretty much usless) I would be greatful.

    I was pretty sure these were ment to be sealed but I am reading conflicted threads.

    Anyway thanks!

    Oh and here is a photo of the subs.

    Vas is probably correct, I would need to see Cms to know for sure.

    You can do sealed or vented with a Qts of .4 and it will sound great.

    Enclosure will be relatively large either way.

    Pure SQ.

    .305m=12in sure these are the 10in specs m8?
    second seems if they are the 10in specs 1.75cf with 3in port 6.5in long would tune box to 35hz

    but i doubt those specs are for the 10in
