Slim Soundbar Front Surround Home Theater Sound System, Wireless Subwoofer, and Flat Amplifier. It includes a super slim soundbar that measures just 1.4 inches (36mm) tall, an even slimmer wall-mountable amplifier/control unit and a wireless subwoofer. The 180-watt, 4.1-channel TH-BS7 owes its slim design to JVC?s own Direct Drive speaker technology that uses a unique voice coil design and strong neodymium magnets to deliver outstanding sound quality and a broad soundfield from a super-slim speaker.
