A 4" round port has about 12.5 in^2 of port area, and the tapered vent only helps to decrease port noise. I haven't personally worked with an SA8, but I'm willing to bet that 4 in^2 is not enough. You'll get a lot of port noise and choke the crap outta that driver. As for what a good box design would be, I'll leave that to some of the Sundown guys.
