Features Soundbar w/ Tractrix Horn Technology: The Klipsch RSB-11's soundbar speaker is equipped with two 0.75" horn-loaded textile dome tweeters with 90° x 90° Tractrix horns that deliver crisp highs, plus four 2.5" fiber composite woofers for dynamic midrange and enhanced vocals. By incorporating highly efficient horn-loaded technology into the soundbar, all sounds are more detailed, dialog clarity is significantly improved, and overall output is maximized to cover even the largest listening areas. The tweeters and woofers are bi-amplified and utilize a DSP-controlled crossover network. Wireless Powered Subwoofer: The Klipsch RSB-11 includes a wireless powered subwoofer with an 8" side-firing fiber composite woofer in a bass reflex enclosure with a rear-firing port. The powered sub delivers deep, accurate bass to your movie and music soundtracks. The sophisticated 2.4 GHz technology automatically connects the soundbar and subwoofer together wirelessly; up to 50'. The wireless powered sub's cabinet features a black wood-grain vinyl finish and rubber feet. The wireless powered subwoofer has independent volume control from the included IR remote control. Dolby Audio Decoder: The Klipsch RSB-11 incorporates Dolby Audio for rich, clear, powerful sound. Its built-in Dolby Audio decoder allows the Klipsch soundbar system to automatically reproduce detailed, high-output sound in almost any size room no matter what format of sound (including Dolby Digital 5.1 and 2ch PCM) is coming from the TV's output. Sound Modes: The Klipsch RSB-11 soundbar & subwoofer system offers 3 sound modes to choose from - Virtual Surround, Voice Enhance, and Night. The Virtual Surround mode is designed to simulate the effect of a surround sound system. The Voice Enhance mode increases dialogue volume for enhanced vocal clarity without increasing ambient sounds. Night mode adjusts the system's dynamic range for quieter listening environments. HDMI 2.0: The Klipsch RSB-11's soundbar is outfitted with three HDMI 2.0 inputs and one HDMI 2.0 ARC output. The system's HDMI connectivity supports 4K pass-through and is HDCP 2.2 compliant. 4K Video Pass-Through: The RSB-11 lets you maintain 4K quality from source to screen by allowing 4K video to "pass-through" and be displayed on a 4K TV or projector, without compromising image quality. Giving you the pure 4K experience makes this system the perfect partner for 4K-capable TVs and Ultra-HD Blu-ray players. 480i, 480p, 720p, 1080i, and 1080p video signal are also supported (there is no upscaling). HDCP 2.2: HDCP 2.2 is supported by the system's HDMI inputs and output. HDCP 2.2 is short for "High bandwidth Digital Content Protection" and is used for 4K video copyright protection for compatibility with Ultra HD Blu-ray players, 4K Satellite/Cable providers, and 4k online video services. ARC (Audio Return Channel): This feature of the system's HDMI output allows audio to be sent from your ARC compatible TV to the soundbar system through the same HDMI cable already being used to send audio and video to your TV. This eliminates the need for extra cables connected to your television. Note: The soundbar's HDMI input does not support HDR (High Dynamic Range) video Digital & Analog Inputs: In addition to HDMI connectivity, the Klipsch RSB-11 offers an optical (toslink) digital input and a stereo minijack (3.5mm) analog input. Using the digital optical connection, the soundbar accepts sound from both the TV and any device (such as a DVD/Blu-ray player or Cable/Satellite receiver) hooked up to the TV. The system supports Dolby Digital & 2ch PCM audio through its optical digital input. Note: The digital optical output terminals of many newer flat-panel TVs only send an audio signal in 5.1ch when receiving Dolby Digital surround sound from the TV's built-in tuner, network connection, HDMI inputs, or connected USB device; and will output only 2ch stereo from sources connected to the TV via stereo RCA or minijack. Bluetooth Audio Streaming: The Klipsch RSB-11 features built-in Bluetooth for wireless audio streaming of stored music and music apps on your Bluetooth-enabled Apple iPod/iPhone/iPad, Android smartphone/tablet, Windows PC/Phone, Mac computer/laptop, and more to the Klipsch soundbar & subwoofer system. A simple single button press will pair your device with the RSB-11 system. Once paired, the RSB-11 speaker system will automatically re-connect to your device when within range (up to 33').
