Powerful On-wall Speaker for Large Rooms

The Klipsch RP-640D on-wall speaker's robust assortment of drivers and passive radiators make it an excellent addition to home theaters and stereo setups in large rooms. This speaker boasts two Cerametallic woofers and a quartet of 3.5-inch Cerametallic passive radiators, delivering an immense low-end push that emboldens your music and music with stunning weight and realism. Furthermore, an aluminum LTS tweeter coupled with Klipsch’s cutting-edge Tractrix horn ensures spot-on imaging and superb high-definition response. And while the RP-640D speaker offers dual 4-way keyholes for secure vertical or horizontal wall mounting, the included glass base is a perfect choice for those after a less-permanent desktop-mounted setup. Visually elegant and unobtrusive, the RP-640D is sure to finish off your home audio setup with an enveloping wash of authoritative Klipsch sound.

Spun-copper Cerametallic woofers

Each Klipsch RP-640D comes loaded with two 3.5-inch Cerametallic woofers, yielding impressive low-frequency audio reproduction down to 55Hz. In addition, the RP640-D ups the ante with an immense-sounding quartet of 3.5-inch Cerametallic cone passive radiators to further bolster your bass response. We're highly impressed by the quality of these woofers and passive radiators here at Sweetwater; they positively represent the pinnacle of Klipsch's cutting-edge design philosophy. No matter what you listen to, these rigid yet eminently lightweight drivers and radiators will deliver the goods with minimal cone breakup and near-zero distortion.

Titanium-dome LTS tweeters and Tractrix horns

Housed inside every Klipsch RP-640D speaker is a 1-inch titanium-dome LTS (Linear Travel Suspension) tweeter. These tweeters maximize dynamics, ensuring a hyper-detailed sound that's never shrill or harsh. The RP-640D also includes a Tractrix horn, arming you with unrivaled high-frequency response and extension, along with spot-on directivity.
