- Back-throw Bass-reflex Tractrix ® port
- Strong, Flexible Removable Grille
Hybrid Tractrix® Horn Technology
Klipsch proprietary Tractrix ® horn-loading technology ensures that the RP-400M's high-frequency sound energy is directed to the listener, reducing unwanted, artificial vibrations from wall-bouncing sounds – so you hear the clearest , most detailed , lifelike sound .
HORN ANATOMY
Klipsch Reference Premiere series speakers feature a compression molded silicone surface mated to a 90° x 90° Tractrix horn for smoother frequency response. Klipsch computer-built phase plugs act as a mechanical filter to provide a smooth , flat frequency response while protecting the tweeter from damage.
Linear Motion Suspension (LTS) Titanium Diaphragm Tweeter
Exclusive Linear Motion Suspension minimizes distortion for enhanced, detailed performance. LTS tweeters are the most distinguishing feature of the Reference series, making it a key component of the best speakers in the world.
VENTILATED TWEETER DESIGN
The new vented tweeter section reduces standing waves that create unwanted harmonics, resulting in improved detail and clarity in high frequency reproduction.
PREMIUM MATERIALS AND SURFACES
Between the surfaces is ebony vinyl. Ebony models are adorned with satin-painted partitions with a scratch-resistant finish . The mirror-like piano shine is impeccable thanks to the meticulously sanded and hand-polished process.
CERAMETALLIC™ WOOFER
Klipsch Proprietary Cerametallic™ woofers are the signature RP-400M for both sound and aesthetics. These extremely light , rigid materials deliver lower frequencies with maximum efficiency.
WOOFER ANATOMY
Klipsch Cerametallic ™ cones are mated to a double-layer, copper-wound voice coil for exceptional conductivity.
Reference Premiere woofers are housed in a non-resonant steel cabinet, fixed to a large magnet motor for exceptional efficiency and low distortion, and paired with our Horn tweeters for optimum acoustics.
TRACTRIX® PORT
The rear Tractrix port pairs perfectly with cabinet and woofers, providing ideal airflow with minimal distortion or turbulence even at the lowest frequencies.
ROBUST INPUT TERMINALS
Single 5-screw terminals accept up to 12 scales of banana plug or bare wire for flexible, long-lasting connections, while vibrant color coding ensures easy installation and connection.
DRAMATIC DETAILS
Copper anodized trim rings , cast aluminum legs, satin-painted baffles and laser-etched logo application give the Reference Premiere II series a modern, premium look.
