Every Reference speaker utilizes our Tractrix Horn technology for lifelike sound, more output using less energy, improved reliability, reduced distortion and a large soundstage with well-defined imaging.

Titanium tweeter with linear travel suspension trickle-down technology from our flagship Palladium Series provides an open, natural sound, making you feel as if you' re in the studio with the recording artist or on the set of a film.
