Overview

Klipsch R-40M Reference Series 4" Bookshelf Speaker Pair

Klipsch R-40M Reference Series 4" Bookshelf Speaker Pair

All New 90° x 90° Tractrix® Horn

The updated horn design, featuring larger outer dimensions, delivers greater power and emotional impact for both music and movies. The increased size allows for directivity control across a wider range of frequencies, creating a more precise and immersive soundstage.

Linear Travel Suspension (LTS) Aluminum Tweeter

A signature feature of Klipsch speakers, the exclusive 1" LTS tweeter with Kapton Suspension reduces distortion for more detailed sound. The tweeter’s aluminum construction is both lightweight and rigid, delivering high efficiency and precise performance.

Spun-Copper Thermoformed Crystalline Polymer Woofers

Drawing on technology from Klipsch’s acclaimed Reference Premiere series, the 4" TCP woofers feature steeper cone angles for smoother response. This refined design enhances accuracy and transparency, delivering clearer, more precise sound reproduction.

High-Quality Cabinet Design & Appearance

Hidden fasteners, an edge-to-edge horn, and low-profile magnetic grilles create a sleek, modern look. The MDF cabinets feature a scratch-resistant, textured wood grain finish that blends seamlessly with your home décor.
