The DCB 535-SURR is the surround speaker. These speakers use two 1" tweeters and two 5.25" woofers, in a bipole/dipole configuration. There's a small switch at the bottom left as you face the speaker, allowing you to choose between a bipole (in phase) or dipole (out of phase) set-up. There's a matte black textured finish, with a removable black cloth grille, and the speaker measures 19.25” H x 10.50” W x 5.00” D
