Overview

Our take on the Klipsch Reference Premiere RP-640D

Klipsch Reference Premiere speakers have been putting smiles on our customers' faces for years. Their sound is all Klipsch: powerful, hard-hitting, and dynamic — yet accurate and refined, too. With the RP-640D, Klipsch has managed to fit that same great Reference Premiere performance in a thin, flat design that'll look right at home next to your wall-mounted TV.

Versatile options for your home theater installation

This speaker includes a mounting bracket for on-wall installations, plus a nice-looking glass base for placement on a tabletop. Mount one horizontally under your TV to use it as a center channel speaker, and place two more vertically to the sides of the screen to complete the front soundstage of an all-Klipsch home theater. Those iconic copper woofers can make a bold visual statement, or you can use the wraparound magnetic grille to keep 'em under wraps for a more discreet look.

Wall-mount the versatile Klipsch RP-640D by your TV, or place it on a tabletop using the included glass base.

 

Classic Klipsch sound

Klipsch famously mounts their tweeters inside of a flared opening, or horn. This feature helps control the way sound waves are projected into your room, for crisp, focused highs. The 90° x 90° Tractrix® horn used in the Reference Premiere series is a refined version that delivers a wider sweet spot with more precise placement of instruments and vocals.

The RP-640D teams its 1" titanium tweeter with a pair of 3-1/2" copper-spun woofers plus four more passive copper cones that help reinforce the bass frequencies. It all adds up to rich, full sound from a flat-panel speaker that fits easily on your wall or TV stand.

Build a complete Klipsch on-wall system

You can use three RP-640Ds for a powerful front home theater soundstage. Or mix and match as space allows with the smaller RP-240D. For surrounds, consider the ultra-compact RP-140D. And remember, for maximum home theater impact, we recommend adding a powered subwoofer of your choice.

big sound from a thin speaker

JC from Las Vegas, NV on 9/21/2018

Crutchfield Customer Review (What's this?)

I was leaning towards buying a larger Klipsch center channel speaker, vice this on-wall line. Due to my personal constraints in my home layout on getting one of the RP center channel speakers, I was limited to the their on-wall line. I was nervous on how it would sound, but once setup was very impressed. It doesn't have the big bass as the other standard speakers, but more than filled the need. The center needs to focus on the voice/ vocals of what your watching and it does that extremely well. I also have a RP 12in subwoofer that BOOMS along with two RP-260's. So bass is no issue at all. I hung this speaker right off of my 75in QLED tv. The low profile gives it a great look in our home.

Great Sound from Klipsch

Michael from Gainesville, FL on 3/25/2018

I recently sold my Klipsch floor standing speakers which were in a 7.1 configuration to buy 3 Klipsch Reference Premiere RP-640D and two Klipsch Reference Premiere RP-240D and I was a bit worried that I would not be as satisfied with the sound as I was with the bigger heavier speakers. I was wrong in a big way! I love these speakers so much that my current 5.1 configuration is going to be great without having to add two more speakers to get me back to a 7.1 configuration. The sound is very rich and full whether the volume is low or high and the speakers are easy to hang on the wall as they weigh about 9 lbs each. High recommend this series of speakers!!!

Pros: None

Cons: I want to put these in every room in my house!

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).

  • Wall-Mount Dimensions:
    • Vertical: 6.0" (w) x 28.5" (h) x 2.5625" (d)
    • Horizontal: 28.5" (w) x 6.0" (h) x 2.5625" (d)
  • Table-Top Dimensions:
    • Vertical: 9.0" (w) x 29.9375" (h) x 6.0625" (d)
    • Horizontal: 28.5" (w) x 7.125" (h) x 6.0625" (d)

1 question already asked

couldn't really tell because I have never used the G-28 although the Klipsch RP-640D is a powerful speaker! I was amazed on its performance. Another thing though that I like about it compared to the G-28 is its outer finish, it looks really modern and I like the fact that my fingerprints don't stay on it unlike the G-28's finish which is high gloss that you have to constantly wipe with microfiber cleaning cloth to avoid scratches.
