About the Tesseract

The Nostalgia Audio Tesseract is a high-end in-ear monitor (IEM) designed with a hybrid driver configuration of 10 Balanced Armature (BA) drivers and 6 Sonion latest Electrostatic (EST) drivers per side. It features a 5-way crossover design allocating 2 BA drivers for low frequencies, 2 BA for low-mid, 4 BA for mid, 2 BA for high, and 6 EST for ultra-high frequencies. The shell and internal modular components are fully 3D printed to ensure consistent sound quality. It incorporates advanced technologies such as Low-Pass Labyrinth for enhanced bass performance, Spiral Flow Device to improve high-frequency detail and accuracy, and Electromagnetic Shielding Coating (E.S.C.) on drivers to reduce distortion and electromagnetic interference. The Tesseract offers a wide frequency response from 10 Hz to 45 kHz, an impedance of 18 Ohms at 1 kHz, and a sensitivity of 118 dB at 1 kHz with 1 mW input. It comes with a high purity silver cable and is limited to 150 units worldwide, emphasizing exclusivity and precision in sound engineering.
