Tractrix Horn Technology

Klipsch exclusive 90º x 90º 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 clarity, dynamics, and detail from your movies and music.

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 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 high in its class.

Exposed fasteners, low profile magnetic grilles and a scratch-resistant, textured wood grain vinyl give the R-51M bookshelf speakers a polished, modern appearance.
