Our Reference range offers the very best that can be achieved in accuracy and musicality. We are honored that these models are some of the most awarded loudspeakers in the world. They combine advanced materials with cutting edge science and engineering. Designed without compromise, their singular aim is transporting listeners into the heart of the music.
Sonja 3.2 is a true, reference loudspeaker, delivering the life-like, natural sound which is the hallmark of YG. Capable delicate holographic imaging while still recreating concert scale audio, it is one of the very best loudspeakers in the world. With the revolutionary Lattice tweeter, twin BilletCore midrange drivers and our innovative Ultracoherent crossover, it combines an astonishing sonic performance with exceptional engineering and craftsmanship.
The Reference speakers are structured from high- grade aerospace aluminum, machined in-house to an incredible precision. The speakers are meticulously hand-built by experts in our Colorado workshop.
The Reference 3 models include new technologies and design innovations based on novel theoretical models, detailed multi-domain simulations and thousands of hours of listening. The end result: loudspeakers which convey every nuance of emotion, each musical cue from the tiniest micro-detail to the visceral impact of the most thunderous crescendo.
An entirely new, hybrid Lattice tweeter uses a novel airframe in a specially-selected aerospace alloy, machined by YG Acoustics. It delivers exceptionally low distortion over a huge bandwidth, with wide angular dispersion to support a large sweet-spot.
Groundbreaking, third-generation Ultracoherent crossovers apply a deep understanding from simulation to deliver performance never before possible.
Our BilletCore drivers use advanced motors and cones machined in-house from solid billet, offering some of the highest performance and lowest distortion in any driver available today.
