Hi
I found a driver that requires a Port of
2-3/8 Diameter (60mm)
4-3/4 Length (120mm)
And found a Port which is 2-3/4 (about a 10mm in diameter increase)
And if this is ok
Or another option is if i can make a printed piece that connects to the end of the bass port to restrict the flow of air
The same way a one of those water restrictor for a shower head but with air not water
