3.1-channel soundbar elevates your viewing experience with crisp, clear dialogue and room-shaking bass. Its wireless subwoofer eliminates the hassles of a wired connection so you can set it anywhere in the room and surround yourself with richer, deeper bass. Surround Sound Expansion feature lets you sync to additional wireless speakers (sold separately) to add depth and bring a new dimension to your listening experience. Connect your soundbar to your Samsung TV (sold separately) or compatible devices with ease and without the clutter of wires via Bluetooth. Or, connect it directly through HDMI for the best audio and video experience.
