Those are made in 2003 Blaupunkt Overdrive 5 x 7s. No brackets, that is just the speakers and grilles in the piston covers.

5 1/2" round fit great there too. Just watch the rear depth to be sure you clear the cylinder or top spring as it moves through its arc. The speaker has to be very shallow; you can mock it up with cardboard or clay for testing. There was not even enough room to mount this speaker behind the panel like I wanted to.

In '03 there were very few speakers that could fit here, but with the newer magnet technologies thinner speakers are more common. These are also synthetic cones so that water does not destroy them.
