Features

Horn-Loaded Tweeter: The Klipsch Reference Premiere RP-640D features proprietary Tractrix Horn technology coupled with a Linear Travel Suspension (LTS) titanium tweeter to produce clean, natural high frequencies.

• 90° x 90° Tractrix Horn: The Tractrix Horn's geometry helps to improve high-frequency response and extension, while enhancing imaging and dynamics. The 90° x 90° Tractrix Horn also focuses the high frequency sounds towards the listening area, for the cleanest, most natural sound possible.
• LTS Tweeter: Behind the Tractrix Horn lies a 1" titanium tweeter with a Linear Travel Suspension (LTS) for open, natural, sound. The Linear Travel Suspension (LTS) minimizes distortion for enhanced, detailed performance.

Spun-Copper Cerametallic Woofers & Passive Radiators: The RP-640D loudspeaker features two 3.5" woofers and four 3.5" passive radiators made from Klipsch's distinctive, spun-copper Cerametallic material. Made with an anodized aluminum, the 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 woofers and passive radiators also employ a rubber surround for added durability.

ABS Enclosure w/ Wrap-Around Grille: The speaker enclosure is made of ABS and features a matte black painted finish. The speaker also comes with a removable, wrap-around cloth magnetic grille which easily snaps into place over the ABS enclosure.

Spring-Post Terminals: The RP-640D is equipped with spring-post terminals to connect bare speaker wire from 16AWG to 12AWG. Due to the position of the spring-post terminals they will not accept banana plugs or pin-connectors.

Applications: The RP-640D on-wall speaker can be used as a front, center, or surround speaker in a home theater setup.

• Placement for Front Speakers: For the most spacious sound place a pair of speakers 6' to 15' apart with the listening position about 1-.5x the distance separating the speakers. However, excellent sound can still be achieved by placing these speakers close to both sides of your TV if that is more aesthetically pleasing.
• Placement for Center Speaker: Since a center-channel speaker is designed to place dialogue and primary sounds so that they appear to come from the video screen. The speaker should therefore be placed horizontally, as close to the screen as possible, preferably at least 1" directly below the screen.
• Placement for Rear speakers: As rear surrounds, a pair of speakers should be placed approximately 2' above the listening position (typically this will be about 5'-7'above the floor. The surrounds should be placed on the walls directly adjacent to the listening position or on the wall behind the listening position.

Mounting Options: The RP-640D on-wall loudspeaker can be mounted vertically or horizontally when wall-mounted or attached to the included table-top base. The included wall-bracket and dual four-way keyhole slots allow for easy, tight-to-the-wall mounting (mounting screws not included). The included glass base provides a table-top solution for placing the speaker on a stand, table, or shelf (the base attaches to the speaker using the two included screws).
