A CONSTELLATION OF PURPOSE

VOLK Audio X Astell&Kern

Astell&Kern represents the precision of modern engineering. VOLK Audio defines the architecture of design and acoustic form. Michael Graves brings the mastery of a five-time GRAMMY Award-winning engineer who understands the line between control and emotion.

Led by VOLK founder Jack Vang, whose decade of experience helped shape a generation of in-ear design, the project evolved through exchange and refinement. Each discipline strengthened the others, creating an instrument defined by proportion, balance, and restraint. Throughout development, the VOLK engineering team worked closely with Astell&Kern to advance both process and performance.

COLLABORATION

Jack Vang, Founder of VOLK Audio

“ This collaboration was both an honor and a challenge that demanded absolute precision. Both Astell&Kern’s and Michael Graves’ standards for excellence mirror our own, and that alignment pushed every part of the process to its limits. The goal was to create something focused, balanced, and precise, an IEM accurate enough for the most demanding mastering environments yet engaging enough for personal listening.
STELLA carries that philosophy forward, a reflection of what’s possible when precision meets purpose. ”

6-Way Crossover Network

12-Driver Quadbrid Design

STELLA is built on a 12-driver quadbrid architecture that unites four transducer technologies within a single, coherent system. Each element was developed for its distinct role and tuned through precise control of phase, pressure, and motion.


Its design reflects the same discipline that governs its form. Every contour, cavity, and circuit exists to serve acoustic integrity. The structure is shaped by performance, the performance defined by structure. Nothing is decorative, nothing is redundant.Every driver operates within its natural range, contributing its character without interference. No forced equalization. No artificial enhancement. Only precision through purpose.

LF-H – VOLK Low Frequency Hybrid System

The VOLK Low-Frequency Hybrid System (LF-H) serves as the starting point of STELLA’s multi-stage architecture, combining VOLK’s M9-R 9 mm subwoofer and dual balanced armatures within a dual-stage chamber designed to regulate phase and resonance.
The chamber’s geometry, alignment, and crossover were co-developed to maintain phase accuracy and pressure balance between both stages. This coordination allows the dynamic driver to deliver depth and force while the armatures add speed, texture, and tonal structure across the lower band.

Operating from 20 to 600 Hz, the LF-H establishes a foundation of weight and control that defines STELLA’s composure and balance.

MID-RANGE ARCHITECTURE

STELLA’s midrange is formed around a tri-armature array tuned for tonal balance and natural presence. The dual balanced-armature drivers operate from 600 Hz to 7 kHz, voiced for energy and density in the 1–5 kHz range. They deliver warmth, articulation, and a vocal character that connects the low and high ranges with quiet precision.

Above them, a single armature extends from 6 to 15 kHz, overlapping to reinforce upper-mid harmonics and refine vocal and instrumental overtones. Its lightweight diaphragm and quick transient response preserve clarity and texture while integrating precisely with the planar and electrostatic systems above, maintaining linearity across the spectrum.

HF-H – High Frequency Hybrid System

The VOLK High-Frequency Hybrid System (HF-H) defines the upper range of STELLA’s architecture, combining VOLK’s MP-2 dual planar magnetic drivers with four electrostatic tweeters in a unified system.
The crossover and acoustic topology were co-engineered to preserve phase accuracy and tonal stability across the transition between the planar and electrostatic assemblies. This balance allows the planars to shape upper harmonics with precision and control while the electrostatics extend bandwidth and atmosphere with speed and composure.

Operating from 9 to 45 kHz, the HF-H maintains coherence and clarity at the limits of extension, completing STELLA’s spectrum with authority and refinement.

Aluminum Shell and Stainless-Steel Frame

VENT ARCHITECTURE

Machined into the aluminum shell and stainless-steel frame, the vent system regulates airflow throughout the enclosure. Its geometry equalizes internal pressure, stabilizing diaphragm motion and maintaining linear driver response. Each aperture is defined by depth, diameter, and damping profile to balance pressure relief and isolation. This prevents standing waves and suppresses low-frequency bloom while preserving the integrity of the acoustic chamber. The vents function as a unified pressure-control system, ensuring consistency between both channels and completing STELLA’s structural and acoustic equilibrium.
