Product Description
The Klipsch Reference Premiere III RP-5403C center channel speaker is designed to deliver clear dialogue, powerful dynamics, and balanced sound for immersive home cinema systems. Its one-inch titanium LTS vented tweeter works with a flush-mounted Tractrix horn to produce detailed, consistent high frequencies across a wide listening area. Four 5.25-inch Cerametallic woofers with Faraday rings provide controlled midrange and strong bass while reducing distortion. An internally braced MDF cabinet and rear-firing Tractrix ports improve rigidity and airflow for cleaner performance. With 96 dB sensitivity, 150-watt continuous handling, and 600-watt peak capability, this speaker offers effortless output. Ebony and Walnut finishes, copper accents, and a floating grille complete its refined design.
Clear, Focused Center Channel Dialogue
The RP-5403C is engineered for the center position, where voices and on-screen details need to remain easy to understand. Its balanced two-way design projects dialogue with strong presence and controlled tonal character, helping movies, television, and multichannel music sound natural across a broad seating area.
Titanium Tweeter With Tractrix Horn
A one-inch titanium LTS vented tweeter is mounted inside a flush-mounted BMC axial Tractrix horn. This combination supports crisp high-frequency detail, controlled dispersion, and consistent clarity. The vented tweeter design also helps reduce unwanted resonance, allowing delicate effects and vocal nuances to remain clean at higher listening levels.
Quad Cerametallic Woofers Deliver Impact
Four 5.25-inch Cerametallic cone woofers provide the surface area needed for full-bodied midrange and convincing bass response. Their lightweight, rigid construction supports quick movement and accurate sound reproduction, while integrated Faraday rings help lower distortion and improve control throughout demanding movie scenes and dynamic musical passages.
Rear Tractrix Ports Improve Airflow
The bass-reflex cabinet uses rear-firing Tractrix ports shaped to promote smooth, efficient airflow. This design helps reduce port noise and turbulence while extending low-frequency performance. The result is tighter bass support and cleaner output, giving the center channel greater weight without sacrificing the clarity needed for spoken dialogue.
High Sensitivity, Powerful Sound Output
Rated at 96 dB sensitivity, the RP-5403C produces strong sound from moderate amplifier power and can reach impressive cinema levels with less strain. It handles 150 watts continuously and up to 600 watts peak, providing generous headroom for sudden effects, action sequences, and dramatic soundtrack transitions.
Internally Braced MDF Cabinet Construction
The MDF enclosure includes internal bracing to improve structural strength and reduce cabinet vibration. By limiting unwanted resonance, the cabinet allows the drivers to perform with greater precision and consistency. Its low-profile center-channel shape also fits naturally beneath many displays or projection screens in dedicated home theater installations.
Flexible Angle Adjustment for Placement
An included angle screw allows the cabinet to be tilted for more accurate sound direction when placed above or below the screen. This practical adjustment helps aim the tweeter and woofers toward the listening position, improving dialogue focus and maintaining a more convincing connection between the picture and sound.
Premium Finishes With Refined Details
Available in Ebony or Walnut, the RP-5403C combines a furniture-grade appearance with recognizable Klipsch styling. Copper-colored driver accents, clean cabinet lines, and a removable floating fabric grille create a polished look that blends easily with matching Reference Premiere speakers and a wide range of home cinema interiors.
