A ported box has an infinite flat frequency spectrum. It just happens that the boost frerquency will have a larger gain.
There are no negatives to a properly built ported box with a properly designed subwoofer.
My d3 runs a flat curve down to 25hz with a curve that peaks at + .5db in a ported box. Even toby said he surprised at how flat it was.
