Linear Travel Suspension (LTS) Aluminum Tweeter With Kapton Suspension

The 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 additional ribbing increases the overall rigidity for less cone breakup at higher frequencies.

Sleek, Modern Appearance

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

MDF Cabinet With Scratch-Resistant, Textured Wood Grain Vinyl

Stylish aesthetic with absolute durability that results in a seamless integration into any décor

High Quality Cabinet Design

Reinforced 3/4” MDF construction with an all-new bracing design reduces cabinet vibration for less audible coloration and improved sonic accuracy.
