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.
ROBUST INPUT TERMINALS
Single 5-way input 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
Featuring a scratch resistent Ebony vinyl finish that boasts an elegant satin painted
baffle, for a premium look in any listening space.
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.
CAST ALUMINUM FEET
Provides a more modern look with less resonance than MDF or ABS plastic. It is
mechanically designed to minimize surface area in contact with floor, decoupling the
speaker for faster, tighter low frequencies and more detail.
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.
