Due to its large woofer and high-quality tweeter, the MC8 is excellent for use as Left, Center, or Right (LCR) channels in high-end in-ceiling home theater setups. Is the grille included? Yes, it comes with a white, micro-perforated magnetic grille that can be painted to match your ceiling perfectly.
