Nostalgia Audio TESSERACT

Tesseract boasts 10 Balanced Armature drivers and 6 of Sonion's latest Electrostatic drivers. Not only is the shell designed with care, but the internal modular structure of Tesseract is also fully built using 3D Printing. This ensures consistent sound quality across all Tesseract units, meeting the demands of high-end audiophiles. With a 5-way crossover design, Tesseract allocates 2 BA drivers for low frequencies, 2 for low-mid, 4 for mid, 2 for high, and 6 Electrostatic drivers for ultra-high frequencies. To further enhance low-frequency performance, we have integrated Low-Pass Labyrinth technology into Tesseract. The result is an expansive soundstage and an airy sound that audiophiles who pursue perfection will truly appreciate.
