Materials

Sabrina V pioneers a groundbreaking addition to the Wilson Audio materials library: H-Material. Developed as a high-density composite with organic and phenolic properties, this front baffle advancement sets a new benchmark in performance engineering. H-Material is similar to X-Material in inflexibility, yet slightly softer with different construction, which lends itself to be more musical in the mid-range than SabrinaX with its use of X-Material as a baffle substrate

Drivers

At the heart of the Sabrina V lies a symphony of advanced driver technologies shared with Wilson Audio’s most celebrated flagships. The Convergent Synergy Carbon (CSC) tweeter, originally developed for the Alexx V, delivers an astonishingly natural high-frequency response. This lightly coated textile dome tweeter seamlessly blends with the AlNiCo mid-range and 8-inch woofer. The CSC offers extended linearity, refined harmonic detail, and a natural sense of acoustic space.

Wilson Audio has integrated its beloved 7-inch AlNiCo (Aluminum – Nickel – Cobalt) QuadraMag mid-range driver into its smallest floorstanding loudspeaker, the Sabrina V. Originally, it was developed for the Chronosonic XVX and utilized in the Alexx V, Alexia V, Sasha V, and The WATT/Puppy. The AlNiCo QuadraMag driver is renowned for its exceptional ability to settle and maintain linearity resulting in greater depth and dimensionality.

The same 8” woofer used in the Sasha V and The WATT/Puppy anchors the low frequencies and foundation of the Sabrina V system. This driver is specifically chosen for its agility and authority resulting in bass that is articulate, textured, and intimately tied to the rhythm of the music.

Hardware & Resistor Access

Refining the rear bass port dimensions and the mid-range vent geometry has revealed deeper, more natural low frequencies while filling your room with warmth and soundstage dimension.

New rear-panel resistor access simplifies service and tuning— a welcome shift from the previous Sabrina bottom-mount approach. Resistors are secured with high quality tool-less thumbscrews, which makes tweeter and mid-range resistor changes swift and intuitive. This new access point on the back of the enclosure is accentuated with a beautifully machined aluminum frame with the Sabrina V logo.

V-MCD

Taking a page from the Wilson Audio Acoustic Diode design, V-Material has been nested and integrated into the bottom of the Sabrina V enclosure where the spike diode interfaces. This upgraded isolation technology (V-MCD) and enhanced vibration control provide an even quieter background, letting your favorite recordings unfold effortlessly. This is music reproduction at its finest — it feels deeper and more alive. If there are room related issues with vibration management, Sabrina V’s spike thread size enables an easy and direct upgrade path to Wilson Audio Acoustic Diodes if one wishes to further enhance the isolation in their system.

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.
