Linear fireplace, tile surround, granite mantle, & in-wall subwoofer

Detail of tile niche, granite mantle, and new ultra hi-def TV. Simulated wood-grain tile is from Italy and is 8" high x 48" long. Vertical metal edging hides hides the tile edges. Granite mantle helps to deflect heat from the fireplace away from the TV. Granite is "Absolute Black", 2cm thickness. Speaker in foreground is a KEF brand passive subwoofer, powered by an amp housed in the recessed gear rack.
