Ushering in a new era of technological innovation, Volür is a 10-driver hybrid UIEM, building on the heritage of Nio. The pulsating heart of Volür is made up of two new custom 9mm dynamic drivers in a True Isobaric configuration, delivering unprecedented low-frequency capability. While our tia™ high-driver remains the criterion in high-frequency performance, our new tia waveguide optimizes its efficiency while offering greater tuning control. The six low-mid and single high-mid balanced armature drivers carry through to Volür. Their implementation was re-engineered to maximize space while integrating 3D printed acoustic tuning features.
The isobaric low-drivers’ damping decreases low-frequency smear, lowering the noise floor to a darker background between notes and beats, allowing details to shine. This creates more palpable impact, with subtle sub-bass information revealing the artist’s true intentions, and a full sound at low volumes. Mids maintain that signature rich quality; an almost tube-saturated presentation. Upper-mids enhance holographic center imaging that really shines with vocals. Our tia waveguide plays the biggest role in improving HF response since our invention of the direct-radiating driver; increasing clarity and stereo imaging.
The outer shell remains the same size, while all significant structural changes occur internally. The faceplate now features a sleeker chamfer, seamlessly blending with the matte black-finished aluminum shell. The final cosmetic touch comes in the form of an homage to Nio: a dreamy purple abalone chip made from responsibly harvested New Zealand Paua shell. What is soon to be a new benchmark in acoustic delivery, Volür is capable of visceral bass while leaving room for the rest of the spectrum to shine. The saturated mids continue to evoke a similar analog warmth found in Nio, while the highs propel it into the territory of some of the most resolving audio products in the world.
Our cone-to-magnet isobaric driver configuration consists of two drivers connected by an acoustically inert coupling chamber. One diaphragm is fully sealed off, while only the other contributes sound pressure. This complex application results in better damping, lower distortion, twice the power handling (because there are two coils and two motor structures), and extended LF response.
With the iso-group wired in series, we worked with our suppliers to create a new 9mm dynamic driver with an upgraded n54 magnet and 25μm PU/115°C + 19μm Ti Cone to increase sensitivity. To further shape the sound, we used a high-precision textile mesh acoustic low-pass filter (originally developed for Fourté Blanc).
The direct-radiating tia high-driver is fitted with our new tia waveguide to increase the efficiency and general amplitude of the HF band. In order to refine this HF response, special diffusion windows were integrated to the front and side of the waveguide. The tia waveguide also serves as a mounting mechanism, mating to the mid-driver housing, offering exact driver positioning during manufacturing.
