Enhance the audio of your display with the Klipsch Cinema 400 soundbar and subwoofer from RC Willey! It features two 1" tweeters mated to 90 x 90° Tractrix horns and two 3" fiber composite woofers, with an 8" wireless subwoofer for augmented bass response. The soundbar has an HDMI ARC and an optical input for direct connection to your display, Bluetooth connectivity for wireless streaming from your compatible device, and a 1/8" analog input for devices without Bluetooth. A subwoofer output on the soundbar lets you use a second subwoofer, or replace the included subwoofer with one of your own. At just 2.8" tall, you can place the Cinema 400 under your display on a table top, or mount it to the wall with the included hardware.

Easy Plug-and-Play Design

Just plug the included HDMI cable or an optical cable into your TV to upgrade its sound.

Slim Profile Design

Measuring just 2.8" tall, the Cinema 400 is designed to fit below your TV whether wall-mounted or placed on a table top.

Engineered for Clear Audio

Two 1" tweeters with 90 x 90° Tractrix horns are designed to deliver crisp highs, while two 3" woofers help provide clear vocals and dynamic soundtracks. Horn-loaded drivers direct the sound to more efficiently bring detail to your ears.

Dolby Audio Decoding Built-In

The built-in Dolby Digital decoder formats all your Dolby Digital content to help the system output a detailed cinema experience.

8" Wireless Subwoofer

The wireless subwoofer can be placed nearly anywhere in your room. 2.4 GHz wireless technology automatically connects the subwoofer to the soundbar with virtually zero latency. An additional wired subwoofer output lets you add a second subwoofer to your setup, or replace the included wireless subwoofer with a wired one of your choosing.

Bluetooth Audio Streaming

The system works with nearly all Bluetooth-enabled smartphones, tablets, and computers, so you can play music directly from your device.

Dialogue, Surround, and Night Modes

Enhanced virtual surround formats are designed to provide a surround sound effect without additional speakers and wires. Dialogue Mode increases the volume of dialogue for enhanced vocal clarity without increasing ambient sound effects. Night Mode adjusts the dynamic range for quieter listening environments.

Wireless Remote Control

The included remote control lets you control volume, input selection, and subwoofer level.
