Definitive's in-ceiling DI 6.5 STR speakers feature near-invisibility thanks to their small diameters, concealed flange design, and low profile micro-perf grilles. They are as simple to set up as standard flanged flush-mount speakers, and don't need customized sheetrock/spackle abilities to set up yet they are almost invisible. The DI 6.5 STR grille is a mere 8-5/16 inches (21.04 centimeters) in diameter, about the same noticeable size as competitive 5-1/4-inch in-ceiling speaker.
