I have old B&W 110i with drivers broken. I want to use the enclosure in another project

Freq. res. 70hz - 20kHz
Cabinet size 25L
Height: 490mm Width: 260mm Depth: 250mm
Port inner diameter now 50,50mm
Port length now 70mm

Driver i want use in the enclosure is HDS-P830874 Peerless

What would be the new port length and inner diameter?

I can make the enclosure smaller if needed
