Sometime, we need drill the holes be suitable for the speaker cabinet, like as a through hole, and a countersunk hole, then you may fix your speaker unit into the cabinet.
We use a machine to do them, come on, take a look that how it works. Also there are many empty speaker cabinets for your DIY, including full range speaker cabinets, 2 ways, 3 ways, and labyrinth, inverted, and so on. You only select that one is suitable for you, then fix it into the cabinet, connect your power amplifier to enjoy your favorite songs...
