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.

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.

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

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.
