HYBRID TRACTRIX® HORN TECHNOLOGY

Klipsch proprietary Tractrix® horn-loaded technology ensures high-frequency energy of the RP-400M bookshelf speakers are aimed directly at the listener and reduces unwanted, artificial reverb caused by indirect sound bouncing off walls - meaning you experience the most clear, detailed, lifelike sound possible.

HORN ANATOMY

Klipsch Reference Premiere series speakers feature a compressed molded silicon face that is matted to the 90° x 90° Tractrix horn to reduces horn resonance for smoother frequency response. Klipsch computer modeled phase plugs act as a mechanical filter to further ensure a smooth, flat frequency response while protecting the tweeter from damage.

Vented Tweeter

A vented tweeter design reduces standing waves behind the tweeter diaphragm for a smoother high frequency reproduction.

The titanium tweeter diaphragm's light weight yet rigid composition exceeds the performance of aluminum, polymer or silk tweeters.

Klipsch award-winning Linear Travel Suspension technology leverages a piston motion of the titanium diaphragm that lowers distortion and delivers real-to-life sound.

A ceramic magnet housing provides premium performance, Klipsch Reference Premiere tweeters set the standard in acoustic reproduction.
