Hybrid Tractrix® Horn Technology

Klipsch® proprietary Tractrix® horn-loaded technology ensures high-frequency energy of the RP-400MB 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 thats matted to the 90x90 Tractrix horn to reduces horn resonance for a smoother frequency response. Klipsch computer modeled phase plugs acts as a mechanical filter to further ensure a smooth, flat frequency response while protecting the tweeter from damage.

All-New 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.

Cerametallic™ Woofers

Klipsch® Proprietary Cerametallic™ woofers are the RP-400MB bookshelf speakers signature statement for both sound and aesthetics. This extremely light, rigid materials holds its shape while being able to deliver lower frequencies with maximum efficiency.

Woofer Anatomy

Klipsch® Cerametallic™ cones are matted to a dual-layer, copper-wound voice coil for exceptional conductivity.

Reference Premiere woofers are housed in a non-resonating, stamped-steel basket that’s secured to a large magnet motor for exceptional efficiency and low distortion, and matched to our horn-loaded tweeters for optimal acoustic execution.

Rear Tractrix® Port

The rear Tractrix port of the R-400MB bookshelf speakers is perfectly matched to the cabinet and woofers, creating ideal airflow with minimal distortion or turbulence even at the lowest frequencies.

Strong, flexible, removable magnetic grilles provide further options - for both protection and style.
