Featuring Tractrix Horn technology, the Klipsch Reference R-40M Bookshelf Speaker Monitors with 4” woofers deliver the cleanest, most natural sound possible. Adding Dolby Atmos is a snap, with simple and hidden connections on the back of the speakers.


Large 90° x 90° Tractrix® Horn
A large horn design, including increased outer horn dimensions, delivers more power and emotion to music and movies. Bigger definitely means better, with directivity control over a larger bandwidth of frequencies, resulting in a more accurate sound stage.


Linear Travel Suspension (LTS) Aluminum Tweeter
A hallmark of Klipsch speakers, the exclusive 1” LTS with Kapton Suspension tweeter minimizes distortion for more detailed performances. Aluminum is an extremely light and rigid material used in the tweeter assembly to provide high efficiency.


Spun-Copper Thermoformed Crystalline Polymer Woofers
Leveraging tech from Klipsch’s highly acclaimed Reference Premiere series speakers, the 4” TCP woofers have steeper angling of the cones for a smoother response and improved accuracy and transparency.


Refined Atmos Connections
Upgrading to Dolby Atmos is extremely easy with the simple and hidden connections located on the back of the speakers. These refined connections reduce the amount of wire seen and hold them in place for better wire management.


High-Quality Cabinet Design & Appearance
Hidden fasteners, edge-to-edge horn, and low-profile magnetic grilles give the speakers a polished, modern appearance. MDF cabinets with scratch-resistant, textured wood grain fit right into any decor.
