Box subwoofer hole slighty too small for RF T1D412?

[USAFradartech]

Any suggestions on making the hole a tad bigger? low on funds so it will be a temporary fix before getting one custom made. only needs to be 3/16" bigger diameter

sandpaper...

Grab some 60grit and sand. will keep the shape pretty accurate

you can either get to sanding or build 1 or 2 mdf rings to pick the sub up to where it can fit with the taper of the basket.

This works too, just a bit more work/time.

Thanks for all the suggestions, will be going with the sandpaper option.
