Modelling the Speakers and Lights

These are the images I as reference to model the speakers and overhead lights.

To make the speaker, I used a cylinder for the pole and made a box where and placed it where the speakers go.

The clip that holds the speaker was made from a line where I created half a square and used the Bezier corner on the two back vertices to bend out the end to make the U shape.

The speakers were make from a box that I simply bevelled and then added a cylinder for the part inside the speaker and scaled the top face inwards.
