A 250mm spigot on a 450mm box suits an outlet that needs a moderate amount of air through a large diffuser face. Fit the box above the ceiling, attach the diffuser below and connect the 250mm flexible duct to the spigot with tape and a strap. The damper blade gives a simple way to trim the airflow at the outlet when balancing the system.

Check that your diffuser matches a 450mm square box, that the duct run is 250mm and that the ceiling void has at least 320mm of depth for the box.
