Custom waveguides enhance audio dispersion for an expansive soundstage.

Supported by tweeters on either side, the center tweeter fills the room with dazzling vocals and lead instruments.

Widely spaced around the sides to minimize vibration, two high-performance woofers produce balanced bass.

A pair of tweeters evenly covers the room for a consistent listening experience no matter where you’re sitting or standing.

Loaded into a directional horn, the upward firing tweeter reflects sound off the ceiling to bring spatial audio content to life.
