That driver should never have been used in a vented enclosure, at least not one of that size. It can work reasonably well vented, but only in at least 8 cubic feet.
In 2.3 cu ft with the port size you listed it would have an Fb around 65Hz, with an 8 to 10dB hump at 70Hz. I can't imagine listening to that. Making the port 14 inches long would lower Fb to around 40Hz, lowering the hump to perhaps 5dB at 45Hz, which is better. But I'd put that driver into a sealed cab of 3 cu ft or so, heavily stuffed to get the Qtc down to around 0.8. That should give reasonably flat response with an F3 at 45Hz.
