All New 90° x 90° Tractrix® Horn

An updated horn design, including increased outer horn dimensions, will deliver more power and emotion to your 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

Utilizing trickle-down technology from Klipsch's highly acclaimed Reference Premiere series of speakers, the 4" TCP woofers have steeper angling of the cones for a smoother response and improved accuracy and transparency.

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 to fit right into your home décor.

Premium Wire Management

Featuring innovative wire management for discretely adding these Dolby Atmos elevation speakers, you won't see cables sticking out from the back of the speaker. All you'll hear is immersive, 360° sound.
