    I was looking at some UniBox graphs...

    Apparently, a cheap (good) sub with nice Xmax and Qts can deliver a good deal of power (close to a Titanic 10" - 12"), if the box is big enough.

    Even better, the response curve is just -6 dB at 20 Hz.

    If I do build this thing (the box is big - 150 L), is there any other thing to check for than max displacement and group delay? Is building a bigger box an easy solution to flatter frequency response with a less powerful driver? I'd assume this helps reduce overall distortion, too, since the driver doesn't have as much air resistance to overcome as in a small box...

    Thanks for your help!

    Javier.

    Jack,

    The driver is a small Cerwin-Vega, which has 17 mm Xmax. I was wondering whether building a big box for it is a good idea, given the fact that it's not a really complex or expensive driver. I know cheap drivers must do something worse than expensive ones... and I really don't know whether building a big or a small box for them is recommended.

    Not that I'm worried too much about getting this sub wrong... because today, my Tempest AA will be finished!!! [​IMG]
