The Klipsch RP-640D is a slim, wall-mountable Reference Premiere speaker finished in matte black — built to deliver Klipsch’s signature horn-loaded sound from a cabinet thin enough to sit flush beside a flat-panel TV.
The Klipsch RP-640D packs Reference Premiere performance into a slim on-wall cabinet built to sit flush beside a wall-mounted TV, with dual copper-toned woofers and a matching set of passive radiators for surprisingly full sound from a flat-panel speaker.
The RP-640D ships with both a wall-mount bracket for on-wall installation and a glass base for tabletop placement — horizontal or vertical. Mount one under your TV as a center channel, and add a pair vertically on either side of the screen to round out an all-Klipsch front soundstage.
A 1" titanium LTS tweeter sits inside a 90° x 90° Tractrix® horn, controlling how sound waves project into the room for a wider sweet spot with precise placement of dialogue and effects.
Dual 3.5" Cerametallic™ active woofers are reinforced by four more 3.5" Cerametallic passive radiator cones, giving this flat-panel speaker noticeably more low-end weight than its slim 2.4" depth would suggest.
Use three RP-640Ds across the front of a home theater, or mix and match with a smaller on-wall model as budget and space allow. Pair with a Klipsch subwoofer for full-range impact.
I’d invite you to book an appointment at our Ottawa showroom to hear the RP-640D in person — on-wall speakers are hard to judge from a spec sheet — alongside the rest of the Klipsch Reference Premiere II lineup. Our team also handles amplifier matching, professional installation, and delivery anywhere in Canada.
Yes — mount it horizontally under your TV to use it as a center channel, or place two vertically on either side of the screen as left/right speakers.
No, speaker wire is sold separately. Ask us in-store or by appointment for a recommendation that matches your amplifier and run length.
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.
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.
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).

Orders under $99 will have shipping calculated separately and confirmed with you after checkout.
Some large or heavy products — including floor-standing speakers, large subwoofers, and TVs — ship via freight carrier rather than standard parcel courier. For these items:
If freight charges for an oversized item are not already included in your order total, we will confirm the cost with you before shipping.
If the shipping box shows signs of physical damage, we recommend inspecting the product while the shipping company is present. Minor punctures or dents to the box do not often result in damage to the well-padded product inside, so a refusal of delivery is generally not necessary for minor box imperfections. However, should the product itself show signs of damage, it must be refused at the time of delivery for an RMA. Products not refused due to damage at the time of delivery will not be eligible for RMAs. To ensure your full rights to warranty and potential future claims, please have the delivery company note any box damage on file, even if the product itself appears undamaged.
For any questions regarding your order, please contact us.
