Gemini

At YG Acoustics, our greatest inspiration has always been the relentless pursuit of what is possible in audio reproduction. Every day, our team at the Cambridge R&D centre brings passion and ingenuity to pushing these boundaries forward. Our lab is equipped with some of the world's most advanced acoustic and vibration measurement facilities. Benefitting from cutting-edge simulation technology and five years of detailed research on how human ears perceive musical sound, we've can explore new ideas and technologies faster and more thoroughly than ever before.

Our new Ultimate range embodies this relentless spirit. After three years of dedicated development, we proudly present Gemini, the most ambitious loudspeaker YG Acoustics has ever created. Gemini represents our collective vision, designed not just to demonstrate our newest innovations but to connect listeners deeply and intimately with their music, surpassing expectations and creating experiences filled with genuine emotion.

Standing over two meters tall, each Gemini speaker houses a precisely arranged seven-driver symmetrical array supported by a custom-designed sub-bass driver.

Our revolutionary lattice tweeter is supported by 15cm midrange, 18cm mid and 26cm bass drivers, each as a pair above and below the tweeter. Simulation and listening showed the extraordinary advantages of a carefully designed symmetrical arrangement like this. Every driver is meticulously phase-aligned with its neighbors across an extensive frequency range, ensuring a true point-source listening experience.

This approach provides exceptional sound clarity, realistic imaging, and a remarkably flexible listening area—placing you firmly at the heart of the music, whether whisper-quiet or at concert volumes.

The Gemini cabinet showcases our obsessive attention to detail. Constructed from three layers of specially selected aluminium alloy, each separated by precision-engineered damping materials, it achieves extraordinary rigidity and resonance control. The front faceplates are machined from solid, aerospace-grade aluminium, heat-treated to optimize their crystalline structure, then precisely milled to tolerances of a thousandth of a millimeter. Internally, advanced bracing and strategically placed diffusers/absorbers eliminate unwanted reflections, allowing the drivers to perform flawlessly.

Our crossover design is a true testament to the art and science of speaker engineering. Utilizing the very best components available, it is built on a bespoke multilayer PCB material with advanced dielectric properties and internal resonance damping. Each crossover circuit is precisely milled in-house from extra-thick, high-purity copper, with traces optimised through simulation to eliminate interference and distortion. The crossover itself is housed externally, in an elegant enclosure crafted entirely from a specially selected polymer material, which eliminates any field interactions with the crossover signal.

Technical mastery aside, the true measure of Gemini is how profoundly it moves you. Every innovation, every precise machining step, every carefully selected component—these are simply means to a more significant end: the purest, most immersive musical experience imaginable.

Gemini is offered in three distinct versions:

• Gemini Passive: A fully passive five-way, eight-driver configuration with an external crossover, accommodating from one to five amplification channels per tower.
• Gemini Sub:Combines a fully passive four-way system with a dedicated external 1kW amplifier for sub-bass frequencies, carefully phase- and time-aligned to blend seamlessly with the passive drivers, supporting from one to four amplification channels per tower.
• Gemini Live: A fully integrated audio solution, with each channel featuring an external audiophile-grade amplifier and advanced DSP crossover, all connected via glass optical fibre to the Live Controller, providing Roon-Ready streaming alongside comprehensive digital and analogue connectivity.

At YG Acoustics, the Gemini is more than just a speaker; it's a heartfelt expression of our passion for music and engineering excellence—a benchmark of what is achievable when innovation meets relentless dedication.
