Overview GLADEN ZETA ZM 80
The GLADEN ZETA ZM 80 is an 80 mm midrange driver developed for active 3-way systems. Unlike the wider-band ZM 70, the ZM 80 is focused specifically on the midrange.
Its lightweight NPC diaphragm, 25 mm voice coil, and neodymium motor are designed for fast and controlled reproduction. Voices and instruments remain clearly structured with natural tonal balance.
DEDICATED MIDRANGE
The ZETA ZM 80 is designed specifically for the midrange section of an active 3-way system.
Its defined operating range allows the driver to focus on voices, instruments, and the midrange information that is essential to a stable soundstage.
NPC DIAPHRAGM
The Nomex-paper compound diaphragm combines low moving mass with controlled internal damping.
This allows the diaphragm to follow rapid signal changes while limiting unwanted resonant behavior.
25 MM VOICE COIL
The 25 mm voice coil works with the motor system to maintain controlled diaphragm movement during dynamic musical passages.
NEODYMIUM MOTOR
The push-pull neodymium motor provides strong magnetic force in a compact design.
Its dimensions support installation in vehicle locations where available space is limited.
ALUMINUM BASKET
The aluminum basket provides a rigid mechanical foundation for the diaphragm, voice coil, and motor assembly and helps maintain precise alignment of the moving components.
