Product Description

Klipsch RP-400M bookshelf speakers offer maximum versatility without sacrificing performance from a small, yet elegant audio solution. Designed as main speakers for a compact living space or surround sound to support a Reference Premiere speaker system, the RP-400M are the ideal choice for your home theater system.

Exclusive Tractrix Ports

Utilizing Tractrix geometry, the Reference Premiere ports allow for the most efficient, fastest air transfer from the cabinet, which reduces port noise for punchier low frequencies. Klipsch Tractrix ports have custom designed inner flares that help reduce air turbulence entering the port. Less turbulent air helps reduce port noise for cleaner, more powerful bass.

Hybrid Tractrix Horn

90° x 90° tractrix horn loading maximizes efficiency and increases detail while focusing high frequencies towards the listening area. Proprietary Tractrix geometry provides the most efficient transfer of high-frequency waves into the listening area. The phase plug and compressed moulded silicon face ensure smooth frequency response. When combined with the silicon composite, the cleanest, most natural sound possible is created.

Linear Travel Suspension

The exclusive Linear Travel Suspension minimises distortion for enhanced, detailed performance. LTS titanium diaphragm tweeters are a hallmark of previous Reference lines, making it a core component of some of the best speakers in the world. The new vented tweeter housing reduces standing waves that create unwanted harmonics, resulting in enhanced detail and clarity in high-frequency reproduction.

Cerametallic Woofers

A signature feature on the Reference Premiere series, spun copper cerametallic woofers are exceptionally rigid and lightweight for minimal distortion and maximum efficiency. When paired with the Tractrix horn-loaded LTS tweeter, it provides the highest speaker efficiency in its class.

Robust Input Terminals

Single 5-way screw terminals accept banana plugs or bare wire up to 12-gauge for flexible, lasting connections while the vibrant color coding provides easy set-up and connection.

Premium Grade Design

Finished with satin painted baffles and a scratch resistant finish, the speakers have strong, flexible and detachable grilles which connect magnetically for an elegant transition from powerful showstopper to a discrete performance piece. Copper anodized trim rings, cast aluminum feet, satin painted baffles and a laser etched logo treatment give the Reference Premiere II series a modern, premium look.
