Klipsch R-40M Bookshelf speakers

Affordable speakers that can rock the house

Klipsch's Reference speakers have always offered a tremendous value, serving up room-filling, detailed sound without straining your wallet. Their new R-40Ms are affordable bookshelf speakers that work well in both home theater systems and two-channel music systems. These solidly built speakers feature a new 4" woofer and an upgraded horn and tweeter for enhanced, articulate sound.
Next-generation drivers

The R-40M's 4" woofer uses spun-copper TCP (thermoformed crystalline polymer) for its cone material. Klipsch chose this material because of its smooth response and transparency. The woofer also uses some trickle-down technology from the company's more expensive Reference Premiere line. It has a similar cone shape and uses additional ribbing for extra rigidity, which reduces distortion at higher frequencies.

The hallmark 90°x 90° Tractrix® horn features an upgrade too. Klipsch widened it's opening for more high-frequency directivity. That means the 1" LTS (Linear Travel Suspension) tweeter inside the horn has a wider "sweet spot" and delivers more detail inside that sweet spot.
