woww!!
so wuts the deal of two chamber and small port everywhere?

To you and anyone else who is wondering, this isn't some crazy design they made up. It's been around since the 50's in home audio. It's called a DBR (double bass reflex). Essentially you have two tuned chambers, and one chamber fires into the other, while both are ported out the front. Never heard one that I liked, but they do get nice lows. While it is a little different, it's still a DBR at heart.

One diff though is the pic your showed has only 2 ports, whereas an ABC has 3.

AHHH! He's right. Someone told me that they were just "modified" DBR's. Lemans is wrong again //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Since Lemans is wrong do I get a free box?

Looks great. I'm building another one of Pete's designs right now, one of his rear loaded horns. Should be done this weekend. He can design a heck of a box.

i sure could steal it.

would fit like a glove in my explorer!

but he does his boxes to certain woofers, so im guessin it wouldnt perform the same if you used different woofers.
