    Yo guys, I got a deal on some unloaded cabs for next to nothing the other day and I'm thinking I might try and fill them. Now I know this is less then optimum as far as engineering goes. But i figure its worth a shot! It gives me something to play around with and potentially give me some sweet sounding cabs.

    I've been playing around in WinISD for awhile, but it seems to give you dimensions based on speaker choice, not vice versa.

    I have a matching pair of cabs that have the internal dimensions 23 1/2" x 20 3/8" x 12"

    Including the baffle the total internal volume is 5387.89 inches cubed. And the front speaker opening is 13 7/8" across. Which to me seems like an odd size. I'd like to put a 12 or 15" speaker in each of them.

    If anyone with any knowledge on the subject has any insight of any kind it would be really appreciated. Ill post some pictures of them later tonight, I'm just on my way out right now.

    Thanks guys.

    Nope. You can spec any cab size you want and plug in drivers until you find a suitable match.You will need to play with different alignments (port tunings) to get there too, unless it's a sealed cab.
  3. You are starting with 3.325 cubic feet gross internal volume.

    Working backwards from your stated cutout of 13.875" diameter and box volume, this filters down to one driver.
    The Beyma 115Nd/W is a perfect fit for your existing box.
    It requires a cutout of 13.860" which leaves a tiny bit of slop so you don't have to hog out the hole.

    it does have a port I forgot to mention. It is 1 5/8". Thank you though I will play with the program more.

    Thank you very much. I'm not sure I've ever heard of this driver before but I'll look into it.

    I do love this website. Where else can you get this level of knowledge and know how in 15 minutes or less?
  5. Shelf port?
  6. Difficult to calculate and build for an accurate tuning.
