Dynamic Bass EQ

As the human ear perceives frequencies differently with variations in output, Klipsch Reference powered speakers will dynamically match the ear’s ability to hear lower frequencies. Typically, only available with audio/video receivers, dynamic volume is a first for Klipsch powered monitors. What you get is powerful bass whether the listening volume is low, cranked up or somewhere in between.

Custom-Tuned Amplification

Reference powered speakers leverage independent, ultra-low noise amplifiers that are custom designed to maximize system performance and eliminate the need for external amplification. That means that world-class Klipsch engineers have full control of the signal path. We've tuned the components to be an absolute perfect match, making the system sound incredibly immersive and fills your room with incredible acoustics.

Tractrix® Horn Technology

Klipsch exclusive 90x90º Tractrix® horn technology ensures that the speaker high frequency energy is aimed at the listener and reduces artificial reverb or filtering caused by indirect sound bouncing off of walls. Using this proprietary focused technology gives you the best clarity, dynamics, and detail from your movies and music.

Linear Travel Suspension Tweeter with Kapton® Suspension

Klipsch exclusive Linear Travel Suspension (LTS) aluminum tweeter minimizes distortion for enhanced, detailed performances. Using Kapton®, an extremely light and rigid material, in the tweeter suspension provides high efficiency and improve resolution and detail. LTS tweeters are a hallmark of Klipsch speakers, making them some of the best speakers in the world.

Spun Copper IMG Woofers

Injection Molded Graphite (IMG) woofer cones are exceptionally light while being extremely rigid – providing remarkable low frequency response, with minimal cone breakup and distortion. When paired with the Tractrix Horn-Loaded LTS Tweeter, it provides speaker efficiency highest in its class.

Sleek Design

Exposed fasteners, low profile magnetic grilles and a scratch-resistant, textured wood grain vinyl give these powered bookshelf speakers a polished, modern appearance.
