Wide Dispersion Surround Technology (WDST): The Klipsch RS-400 delivers precise sonic detail through the careful positioning of two Tractrix Horn loaded titanium-diaphragm tweeters and two 4-inch woofers. By aligning the two horns at 90° with respect to each other, along with the two woofers, the RS-400 smoothly covers a 180° horizontal arc, allowing maximum placement flexibility. This unique Wide Dispersion Surround Technology delivers a new dimension of reality and convenience, and produces a smooth, seamless broad distribution of sound, which is the perfect vehicle for every surround format.

• Tractrix Horn Tweeters: The RS-400 utilizes dual Tractrix Horns for a more genuine, lifelike sound. The square Tractrix Horns deliver a 90° wide by 60° high dispersion pattern for a broader sound-stage. In addition, behind each horn lies a 1" titanium tweeter with a powerful neodymium magnet motor structure to provide a unique combination of precision, clarity and effortless dynamics.
• Cerametallic Woofers: The dual 4" woofers of the RS-400 surround loudspeaker feature Klipsch's distinctive, copper-colored Cerametallic material. Made with an anodized aluminum, this cone is strong and dent resistant. The anodizing process converts its inner and outer surfaces to ceramic. The outcome is a rigid cone with superb damping characteristics that will not flex or resonate at frequencies within the woofer's operating range The 4" woofers also employ a rubber surround for added durability.

Klipsch Horn Technology: Klipsch employs Horn Technology to deliver these four principles of great sound.

• High Efficiency: Klipsch speaker employs horn technology because the horn shape is perfect for accurate and dynamic sound transmission. Greater efficiency means lower distortion, which means maximum realism.
• Dynamic Range: Klipsch horn technology reproduces the softest sounds with remarkable clarity and detail and the loudest sounds with no harshness or distortion.
• Controlled Directivity: Unique Klipsch horn technology means speakers that more accurately direct sound and offer a more lifelike soundstage.
• Flat Frequency Response: Klipsch horn technology delivers exactly the sound the artist intended, with no unnatural highs, mids, or lows.

Bass Reflex Enclosure: The dual 4" Cerametallic cone woofers and dual 1" titanium diaphragm compression drivers are mounted in a bass reflex enclosure which features two side-firing ports (one one each side). The twin side-firing ports eliminate turbulence noise, while increased baffle ribbing around the horn mouth dramatically improves acoustics across the sonic range. The bass reflex enclosure features a MDF cabinet finished with a Matte Black vinyl and an aluminum front baffle. The RS-400's rigid cabinet offers improved internal cross-bracing to minimize panel vibrations that can color sound.

Binding Posts: The Klipsch RS-400 is equipped with sturdy binding posts to ensure a secure connection to many types of cable and connectors. The binding post terminals will accept banana plugs (single only), pin-connectors, spade-connectors, and bare wire (up to 10AWG).

Mounting: The Klipsch RS-400 features a back-panel keyhole slot for on-wall mounting and dual 1/4"-20 threaded inserts for attachment to popular adjustable wall/ceiling brackets and 3rd-party stands (sold separately). The speaker also come supplied with four self-adhesive rubber feet so you can sit the speaker on a stand or shelf securely. The rubber feet add approximately 0.3125" to the height of the speaker.

Placement: The Klipsch Wide Dispersion Surround Technology surround speakers in a typical 5.1-channel system can be mounted to side or rear walls. It is recommended that the RS-400 be mounted above the ear height of seated listeners (between 5' to 7' above the floor).
