VRC

Acora Acoustics VRC – Natural Granite Reference Speakers

At Son Ultime, some speakers are not merely selected for their performance, but for their ability to redefine musical reproduction standards within a complete system. The Acora Acoustics VRC are among these benchmarks.

Manufactured in Canada and machined from solid natural granite, the VRC embody a radically different approach to loudspeaker design: eliminating cabinet resonances to allow the transducers to fully express themselves.

A platform we chose for the Montreal Audiofest 2026

The Acora Acoustics VRC have been selected by Son Ultime as the main speakers for our demonstration system at the Montreal Audiofest 2026.

This choice is significant. It reflects our desire to present a system capable of:

• Revealing the finest micro-information
• Maintaining absolute stability of the soundstage
• Supporting reference electronics without limitation
• Offering an immersive and credible musical experience

In a demanding context like an audio show, where conditions are variable, the VRC stand out for their consistency and their ability to perform at a very high level.

Solid granite architecture – resonance control

The VRC cabinet is entirely machined from solid natural granite, offering exceptional rigidity and inertia.

• Monolithic granite structure
• Almost complete absence of cabinet resonances
• Extreme mechanical stability
• Reduction of structural colorations

Unlike traditional materials, granite effectively dissipates unwanted vibrations, improving the precision and legibility of the acoustic signal.

Transducers and acoustic behavior

The VRC use carefully selected high-end transducers, integrated into an architecture optimized for signal coherence.

• Low-distortion loudspeakers
• Crossover optimized for temporal coherence
• Extended and linear frequency response
• Controlled dispersion

The result is stable, precise, and extremely transparent reproduction, capable of revealing the differences between electronics and sources.

Observed sound behavior at Son Ultime

In our reference systems, the Acora VRC demonstrate remarkable qualities:

• Extremely stable three-dimensional soundstage
• Black background allowing fine reading of micro-details
• Fast, articulate, and perfectly controlled bass
• Absence of perceptible cabinet coloration
• Ability to ramp up dynamics without compression
• Great coherence across the entire spectrum

They act as a neutral platform, faithfully revealing the characteristics of the upstream electronics.

Technical Specifications

System integration according to the Son Ultime approach

The VRC are designed to operate in systems where every element is optimized. At Son Ultime, we integrate them into chains comprising:

• Audio Research amplification
• MSB Technology digital sources
• REL Acoustics subwoofers for bass extension
• Shunyata Research cabling and power
• HifiRose streaming and Silent Angel optimization
• Advanced acoustic correction with Trinnov Audio

Each system is calibrated to exploit the neutrality and transparency of the VRC.

Positioning in the Acora Acoustics universe

The VRC represent a reference approach in the Acora philosophy, emphasizing structural rigidity, neutrality, and acoustic precision.

They form an ideal base for systems aiming for uncolored reproduction and faithful playback of the musical signal.

Son Ultime Approach

At Son Ultime, the Acora VRC are not merely installed. They are integrated into a global system where every parameter is controlled:

• Precise positioning in the room
• Interaction with acoustics
• Optimization of electrical power
• Full system calibration

It is this approach that allows the VRC to reach their full potential.
