REL Acoustics Wood Grille for S/550 Subwoofer

The S/550 comes with REL's standard cloth grille, which matches the fabric color to the subwoofer's, and has a heavy wood frame. You can optionally select the Premium Wood grille that uses real wood in a frame that matches the subwoofer color.  As this uses a natural material, grain and color variations are expected and unique to each grille.
