Founded in 2002, Colorado-based YG Acoustics has focused on the “ultra” high-end loudspeaker market and done rather well in the process. The manufacturer now offer two very distinct loudspeaker lineups including the “Peaks” and “Reference” series models that are designed for audiophiles with very deep pockets.
Have you ever wanted to experience a $150,000 to $200,000 high-end system and not feel guilty when you don’t pull the trigger post? We expect some interesting sonic fireworks when YG Acoustics and Vinnie Rossi demonstrate the new Sonja 3.2 along with Rossi’s BRAMA electronics in Virginia.
Rossi has come a long way from the iMod iPod that he offered almost 17 years ago; EIC Ian White reviewed one of the first samples and owned a number of his battery-powered amplifiers over the years. The new BRAMA Collection was designed specifically for demanding loudspeakers like the Sonja 3.2 and 3.3 and was one of the most interesting new product lineups at AXPONA 2023.
YG Acoustics Reference Series
YG Acoustics loudspeakers are built from the highest-performance materials, and manufactured in-house to unprecedented precision. YG-made speakers are designed to provide nuance and the tiniest micro-detail through to the physical impact of the listening experience.
Two entries in their Reference Series are the Sonja 3.2 and 3.3 which feature a modular design with different bass modules (lower half). As part of the version 3 update to their reference line speakers, the Sonja 3.2 and 3.3 include several improvements.
What’s Improved?
Lighter and Stiff Cones: The Sonja speakers incorporate a lighter and stiffer cone design. Back wave damping and absorption inside the cabinet have been updated and a new constrained layer of damping material between layers of the cabinet walls has been integrated into the design.
Crossover: Crossover improvements include a new electrical design, with a major focus on vibrational damping, reduction of energy loss, and reduction of potential eddy currents.
A new PC board material has been implemented that has a low dielectric constant at RF. 3.1mm; multiple sheets of this material are adhered to a thick copper layer (4x the industry average, and twice the thickness of previous YG Acoustics crossovers). CNC machines have been used to cut and mill out the PCBs. The Reference 3 series also used proprietary custom capacitors.
New Tweeter: Reference 3 speakers also include a new tweeter (aka Lattice tweeter) with combines a featherweight aluminum insert adhered to the silk dome. This new design lowers distortion above the human hearing range (20 KHz to 45 KHz) by an astonishing 6dB.
This in combination with a new waveguide update maintains at least a 15-degree dispersion pattern all the way up to 45 KHz. This improves the width of the existing listening sweet spot to at least 1.5 listeners.
Phase Matching: In addition to the above improvements, YG Acoustics provides perfect phase matching between the drivers to more than 3.5 octaves above and below each crossover point. This means that the slopes match exactly, extending far into the active range of each driver. This ensures that the phase-linearity of these speakers stands out from the competition.
