Klipsch Reference Premiere RP-404C 4" 500W 8 Ohm Spun-Copper Center Channel Speaker (Walnut)

90° x 90° SILICON COMPOSITE HYBRID TRACTRIX® HORN
Horn loading maximizes efficiently 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 molded silicon face ensure smooth frequency response. When
combined, the cleanest, most natural sound possible is created.

LINEAR TRAVEL SUSPENSION (LTS) TITANIUM DIAPHRAGM TWEETER
The exclusive Linear Travel Suspension minimizes distortion for enhanced, detailed
performance. LTS tweeters are a hallmark of previous Reference lines, making it a
core component of some of the best speakers in the world.

VENTED TWEETER DESIGN
The new vented tweeter housing reduces standing waves that create unwanted
harmonics, resulting in enhanced detail and clarity in high frequency reproduction.
SPUN COPPER CERAMETALLIC WOOFERS
A signature feature on the Reference Premiere series, 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.

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.

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.

FURNITURE GRADE MATERIALS AND FINISHES
Finishes include ebony vinyl, walnut vinyl and piano gloss. Ebony and walnut models
boast satin painted baffles with a scratch resistant finish, while the premium piano
gloss cabinet is hand-sanded for a clear, mirror-like finish. The mirror-life piano gloss
finish is seamless due to the meticulous hand sanded and hand polished process.

STRONG, FLEXIBLE, REMOVABLE GRILLE
Attaches magnetically for an elegant transition from powerful showstopper to
discrete performance piece.

DRAMATIC DETAILS
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.
