Interesting the sealed bx RE recommended to them was over 2.8ft^3....almost 3 times their recommended specs...they really went "safe" with the regular specs. So that means a good ported box would have to be MUCH bigger then 2.2ft. right now my box is about 3.3ft^3 tuned to 28hz, and god daamn it sounds good with 2800w:crazy:
I'm happy it was given a bigreview like that instead of just forum people reviewing. The ghey thing is they only tested it sealed, with 2000w. That's gay, I KNOW that it didn't eve go 2/3 of its xmax. Using 2800w and a ported box I've only gotten it to 3/4 xmax on really low notes. They needed a ported box, that's what the XXX is designed for IMO.
