Perfect Smooth Edges On Speaker Boxes

The quest for perfectly smooth sides from 90 degree wood joints is over. You don't have to struggle with making sure you clamp your lumber together exactly in the right spot, or sand until the cows come home. A flush router bit is all you need to get the perfect corner.

I just today did all the same things you mentioned.

Excellent work! Hopefully all worked out all, and better yet, they sound amazing?

Better not to do slotting, pre-cut so that the router only has to take off a tiny bit.

I personally probably won't, I had a cabinet builder do most of my cutting, and after watching him work I understand how they get perfect fits. For us average home builders I think you're right. We just don't have the tools for it.
