Tesseract

Nostalgia Audio Tesseract: Precision Redefined in Sound Engineering

The Tesseract is a cutting-edge IEM designed for audiophiles who demand perfection, featuring a sophisticated configuration of 10 Balanced Armature (BA) drivers and 6 advanced Sonion Electrostatic (EST) drivers. Its fully 3D-printed shell and internal modular design ensure unparalleled consistency in sound quality across every unit. Engineered with a precise 5-way crossover system—2 BA for lows, 2 BA for low-mids, 4 BA for mids, 2 BA for highs, and 6 EST for ultra-high frequencies—the Tesseract delivers exceptional clarity, balance, and detail across the entire spectrum. Enhanced by Low-Pass Labyrinth technology for refined bass depth, it provides an expansive soundstage and ultimate transparency, offering an immersive listening experience for those seeking the pinnacle of audio excellence.

Balanced Armature drivers

Tesseract uses ten Balanced Armature Drivers on low, low-mid, mid and high frequencies. Our SFD system is implemented to reduce losses from the tube curvature, presenting a smooth, sweet vocal also detailed highs and extensions.

Electrostatic drivers

 

The Tesseract incorporates six Electrostatic (EST) drivers, delivering unparalleled precision and detail. A built-in voltage transformer ensures that the EST drivers operate seamlessly without requiring an external power source. These six EST drivers excel in providing the most accurate transient response, revealing limitless nuances and details, making the Tesseract a true benchmark for high-resolution audio performance.

LPL - Low Pass Labyrinth

Consisting of Large Composite BA Drivers and a Built-in Labyrinth. By using high-precision 3D printing technology, a 72 mm ultra long bass duct structure is built for a powerful, slamming bass response.

SFD - Spiral Flow Device​

The SFD is specially designed for enhancing the Mid performance in Tesseract. A helical formation incorporated as a ridge serves to induce a spiral pattern of flow, reducing loss caused by the curvature of the nozzle, and polishing up the vocal performance. 

​

Fully 3D-Printed Design
The Tesseract features a fully 3D-printed design, showcasing precision and innovation in every detail. Beyond the shell, a meticulously engineered 3D-printed acoustic tube structure is implemented to optimize driver placement, minimize size, and deliver precise, solid sound. Constructed from medical-grade 3D-printed materials, the design ensures maximum comfort, tear resistance, skin-friendliness, and biocompatibility, making it suitable for extended wear.

 

E.S.C. Technology
Equipped with ESC (Electromagnetic Shielding Coating) technology, the Tesseract sets a new standard in audio innovation. This advanced coating, crafted from a unique blend of metal oxides and conductive polymers, is applied to all drivers to provide robust protection against electromagnetic interference. By forming a highly effective shield, ESC technology eliminates distortion and external interference, ensuring a pure and uninterrupted listening experience. Designed for audiophiles and music professionals alike, the Tesseract delivers pristine sound quality with unparalleled clarity and precision.
