Sonic Style

Drawing inspiration from the very instruments our speakers meticulously reproduce, the Klipsch Reference Premiere Piano Black series presents our high-performance speakers in an aesthetic that exhibits a bold and elegant audio centerpiece.

True Piano Black Finish

Crafting this incredible finish for our most popular home theater speaker series requires a painstaking, three-coat paint and polish process. By delicately fabricating each layer, the result is a deep and vivid reflection that only a true piano black finish possesses. The luminous finish wraps around the entirety of the housing to provide an even reflection that gives the speaker an edgeless appearance from every angle.

Hybrid Tractrix® Horn Technology

Klipsch proprietary Tractrix® horn loading technology ensures high-frequency energy of the Reference Premiere Piano Black series speaker is aimed directly at the listener and reduces unwanted, artificial reverb caused by indirect sound bouncing off walls - meaning you experience the most clear, detailed, lifelike sound possible.

Horn Anatomy

Klipsch Reference Premiere series speakers feature a compressed molded silicon face thats matted to the 90x90 Tractrix horn to reduces horn resonance for a smoother frequency response. Klipsch computer modeled phase plugs acts as a mechanical filter to further ensure a smooth, flat frequency response while protecting the tweeter from damage.

All-New Vented Tweeter

A vented tweeter design reduces standing waves behind the tweeter diaphragm for a smoother high frequency reproduction.

The titanium tweeter diaphragm's light weight yet rigid composition exceeds the performance of aluminum, polymer or silk tweeters.

Klipsch award-winning Linear Travel Suspension technology leverages a piston motion of the titanium diaphragm that lowers distortion and delivers real-to-life sound.

A ceramic magnet housing provides premium performance, Klipsch Reference Premiere tweeters set the standard in acoustic reproduction.

Cerametallic™ Woofers

Klipsch proprietary Cerametallic™ woofers are the Reference Premiere Piano Black series signature statement for both sound and aesthetics. This extremely light, rigid materials holds its shape while being able to deliver lower frequencies with maximum efficiency.

Woofer Anatomy

Klipsch Cerametallic™ cones are matted to a dual-layer, copper-wound voice coil for exceptional conductivity.

Reference Premiere woofers are housed in a non-resonating, stamped-steel basket that’s secured to a large magnet motor for exceptional efficiency and low distortion, and matched to our horn-loaded tweeters for optimal acoustic execution.

Tractrix® Port + Dual Terminals

The rear Tractrix port geometric design creates ideal airflow with minimal distortion or turbulence for clean, precise low frequency performance.

The Reference Premiere Piano Black series speaker features dual input terminals so you can bi-wire or bi-amp your speakers for a custom, high-performance experience.

Finished to Perfection

Copper trim rings around the tweeters and woofers accentuate the Reference Premiere series features and deliver a premium aesthetic.

Strong, flexible, removable magnetic grilles provide further options - for both protection and style.
