Klipsch R-40PM Powered Bookshelf Speakers — Reference-Series Hi-Fi Without the Receiver

The Klipsch R-40PM powered bookshelf speakers bring Reference-series hi-fi to a single pair of cabinets, with no A/V receiver required. A customized internal amplifier is tuned to the drivers, so the system is ready to play as soon as it's plugged in and connected to a source. Inside each enclosure, a 1" LTS aluminum tweeter sits inside an edge-to-edge 90° x 90° Tractrix horn, while a 4" copper-spun TCP woofer handles the midrange and bass. The R-40PM is the right choice for listeners who want legendary Klipsch dynamics in a compact, self-contained package.

What Sets the R-40PM Apart

The R-40PM stands out because it carries over trickle-down technology from Klipsch's Reference Premiere line. Woofer cones use Thermoformed Crystalline Polymer (TCP) with steeper angling for smoother response and improved rigidity, while the LTS (Linear Travel Suspension) tweeter pairs an aluminum dome with a Kapton suspension to minimize distortion at high output. A rear-firing bass-reflex port extends usable low frequencies down to 60 Hz without needing a subwoofer.

Driver Technology and Sound Character

The horn-loaded tweeter is the heart of the Reference sound. By coupling the 1" aluminum dome to a 90° x 90° Tractrix horn, the speakers deliver controlled directivity, sending more music to the listener and less to the walls and ceiling. This produces a wider, more stable stereo image and lets the speakers fill medium-sized rooms with ease.

• Tweeter: 1" LTS aluminum dome with Kapton Suspension — high efficiency and low distortion for clean, detailed highs
• Woofer Cone: 4" copper-spun TCP (Thermoformed Crystalline Polymer) — steeply angled for smoother response and improved rigidity

Built-In Amplification and Connectivity

The integrated amplifier is the key to the R-40PM's plug-and-play appeal. Because the amp is tuned to the drivers, listeners get matched performance without the cost, complexity, or rack space of a separate A/V receiver. A full input panel on the back covers virtually any source a listener might own.

• Maximum Output Power: 240 W — enough headroom for medium to large rooms
• Inputs: Bluetooth, phono (with ground screw), USB, optical, analog RCA — turntable, TV, computer, phone, and streaming all covered

Cabinet, Dimensions, and Subwoofer Expansion

The MDF cabinet uses extra internal depth for warmer, more impactful sound from a small footprint. Low-profile magnetic grilles let owners choose between the copper-and-black look of the exposed TCP woofers or a clean, all-black appearance. An RCA line-level output on the back panel makes adding a subwoofer — such as the matching Klipsch R-101SW, R-121SW, or RP-1000SW — a one-cable upgrade.

• Cabinet: MDF with rear-firing bass-reflex port — extended bass response and reduced cabinet resonance
• Dimensions (D × W × H): 25.65 × 14.48 × 29.97 cm — compact bookshelf footprint that fits desks, stands, and consoles
• Weight: 8.3 kg per active speaker — solid, vibration-resistant build
• Subwoofer Output: RCA line-level — pairs with Klipsch R-101SW, R-121SW, or RP-1000SW for full-range 2.1 systems

Who the Klipsch R-40PM Is For

The Klipsch R-40PM is the right choice for vinyl enthusiasts who want a turntable-ready system without buying a separate phono preamp and power amp. It suits desktop listeners and home-office users who need powerful, room-filling sound from a small cabinet, and it works equally well as a TV audio upgrade in a living room or bedroom. Because the speakers are self-powered and accept Bluetooth, optical, USB, and analog sources, they fit any setup where simplicity, footprint, and Reference-series dynamics matter more than rack space and component count.

Klipsch and the Reference Series

Klipsch is one of the first U.S. loudspeaker companies, founded in 1946. The Reference series — refined with each generation — is the company's most recognized line, defined by horn-loaded tweeters, copper-spun woofers, and high-efficiency designs. Part of the latest Reference generation, the R-40PM brings the same acoustic philosophy that built the brand into a compact, self-powered format for modern listening spaces.
