This Zu Audio Undertone Subwoofer is available now in the dark espresso finish. The cabinet is in great shape and the sub functions perfectly. It’s rated 7/10 due to the absence of the original box and owner’s manual, but rest assured—it will be professionally packed if shipping is required. A solid low-frequency extension option to complement any system.
