Foster,
The other thing that comes to mind is to make sure the driver is tightly secured to the cabinet. With my F-5s, there are 4 wing nuts that must be tight to secure the driver else the bass levels suffer. These worked slightly loose after some initial playing time and I found that a tight fit is key to good bass.
How are your drivers secured to the base? Is there anything that might need tightening?
