This high-impact, polystyrene plastic recessed grille has an attractive ceiling-white finish in round styling. The acoustical louver design provides maximum sound transmission and dispersion. The 8" (203mm) dia. speaker cone is not visible through the louvers and the speaker mounting screws are hidden for a clean appearance. The high-impact polystyrene plastic will not crack or chip and the baffle contains no components which promote mildew growth. Baffle may be easily repainted on the job site to match any decor. Units install via screw-mount installation.
