Bigger Horn | Better Sound

Hear every word of the dialogue and lyrics with crystal-clear precision.

A new, larger 90^° x 90^° silicone composite hybrid Tractrix^® horn provides incredibly efficient transfer of high-frequency waves into the listening area to create a crisper, clearer sound.

Linear Travel Suspension (LTS) Titanium Diaphragm Tweeter

The exclusive 1" LTS minimizes distortion for enhanced, detailed performance. LTS tweeters are a hallmark of previous Reference Premiere Series, making it 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.

All-New Cerametallic Woofers

A signature feature on the Reference Premiere series speakers, the four 5.25" Cerametallic^™ woofers have been updated for absolutely flawless sound reproduction, minimum distortion, and maximum efficiency. The redesigned woofer will deliver the power, detail, and emotion you expect from a Klipsch Reference Premiere speaker.

Tractrix Port

Utilizing Tractrix geometry, the Reference Premiere port allows for the most efficient, fastest air transfer from the cabinet, which reduces port noise for punchier low frequencies and cleaner, more powerful bass.
