The Linear Travel Suspension (LTS) aluminum tweeter with Kapton suspension reduces distortion for enhanced, detailed performances, and the Spun-copper Thermoformed Crystalline Polymer (TCP) woofers with additional ribbing increase rigidity for improved accuracy and transparency. The Klipsch R-40M speakers also have a sleek, modern appearance with hidden fasteners, edge-to-edge horn, and low-profile magnetic grilles, and are constructed with reinforced 3/4″ MDF and scratch-resistant, textured wood grain vinyl for added durability and improved sonic accuracy.

All New 90° X 90° Tractrix Horn

Our exclusive Tractrix® horn technology delivers the power, detail and emotion of the live music experience with the cleanest, most natural sound possible. The increased outer horn dimensions allow for directivity control over a larger bandwidth of frequencies, resulting in improved high frequency directivity and a more accurate sound stage.

Linear Travel Suspension (LTS) Aluminum Tweeter With Kapton Suspension

The Klipsch R-40M exclusive Linear Travel Suspension (LTS) minimizes distortion for enhanced, detailed performances. Aluminum is an extremely light and rigid material used in the tweeter assembly to provide high efficiency and improve resolution and detail. LTS tweeters are a hallmark of Klipsch speakers, making it a core component of some of the best speakers in the world.

Spun-copper Thermoformed Crystalline Polymer (TCP) Woofers

Utilizing trickle-down technology from Klipsch’s highly acclaimed Reference Premiere series, the TCP woofers have steeper angling of the cones for a smoother response and improved accuracy and transparency. The Klipsch R-40M additional ribbing increases the overall rigidity for less cone breakup at higher frequencies.

Hidden fasteners, edge-to-edge horn, and low-profile magnetic grilles give the speakers a polished, modern appearance.
