Product Information

90° x 90° Silicon Composite Hybrid Tractrix Horn

Horn loading maximizes efficiency and increases detail while focusing high frequencies on 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. The second generation increases horn size for a larger soundstage and enhanced directivity.

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 them a core component of some of the best speakers in the world.

Vented Tweeter Design

The vented tweeter housing reduces standing waves that create unwanted harmonics, resulting in enhanced detail and clarity in high-frequency reproduction.

Cerametallic Woofers – All-New Design

A signature feature of the Reference Premiere series, Cerametallic™ woofers are exceptionally rigid and lightweight for minimal distortion and maximum efficiency. New voice coils are 70% larger in diameter resulting in improved power handling and greater cone control for greater linearity and flawless reproduction. New aluminum shorting rings reduce distortion as well as increase power handling and the new motor structure improves transit response with more control, greater speed, and accuracy.

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.

New and Improved Input Panel

Featuring audiophile-grade wire and easily accessible aluminum binding posts for any connection type.

Furniture Grade Materials and Finishes

Finishes include ebony vinyl and walnut vinyl that boast satin painted baffles with a scratch-resistant finish.

Strong, Flexible, Removable Grille

Attaches magnetically for an elegant transition from a powerful showstopper to a discrete performance piece.

Cork Pads

Cork pads replace rubber bumpers for security on a stand or table.

Weak sound
I bought this through Klipsch last November. Movie dialogue is weak and easily drowned out by the front speakers. You really need to crank up the sound to hear the dialogue. It was pretty disappointing considering the price.

Like hearing Music and Movies for the first time
Those with discerning listening requirements will truly appreciate this center speaker. The presence, clarity, and distinction between vocals and individual instruments is prenominal. I recently upgraded to Klipsch RP towers as my main fronts, and was so impressed with those I thought a center upgrade could also provide appreciable improved listening pleasure. This center replaced my R34C and YES, well worth the upgrade. I am hearing the subtleties in music that were never heard before. Even my non audiophile friends appreciate the quality and sound reproduction this speaker is capable of. The center speaker being the most important in movie surround, this speaker provides the utmost in vocal clarity, presence and an immersive warm ambiance. Wholeheartedly recommend!

Excellent center speaker
I'm getting older, and need more fidelity in the voice range. I updated from a RC25, which performed well for many many years, and is now going to my daughters house :-). The 504c is a significant upgrade. It really rocks, and has a much greater range. I can really crank up the mid-range, and it's very clear.

Amazing center channel speaker
Wow can't believe how much this speaker was needed. It really ties the system together. If you upgrade to the spl150 you need to get this speaker in order to keep up with this sub that will overpowet your R-34C

Klipsch Supremacy
This center channel is certainly the soundstage of my home theater system. It’s not only amazing to look at, but sounds great as well. I’m glad I upgraded with these speakers. Well worth the money!!!
