Tractrix® Horn Technology
Klipsch exclusive 90×90º Tractrix® horn technology ensures the R-820F 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.
