Gladen ZETA 165

The Gladen ZETA 165 is a high-quality 165-mm low-midrange driver for high-end car audio systems that impresses with precise impulse response, natural timbres, and powerful low-midrange sound. As a further development of the proven ZERO PRO series, it combines selected technologies from GLADEN AEROSPACE’s development with a particularly controlled and dynamic sound signature.

The innovative Nomex Paper Compound (NPC) diaphragm combines light weight with high stability and excellent internal damping. This ensures that fast bass impulses are reproduced with precision, while voices and instruments retain their natural tonal character. The suspension system with extended cone excursion ensures controlled reproduction even during dynamic musical passages.

A powerful neodymium magnet drive delivers high magnetic efficiency in a compact design. The torsionally rigid die-cast aluminum basket ensures stable guidance of the moving components and supports low-distortion playback.

With a power handling capacity of 150 watts RMS and 225 watts maximum per speaker, as well as a nominal impedance of 3 ohms, the ZETA 165 is ideal for high-power, actively driven two- and three-way systems. When combined with GLADEN ZETA tweeters and midrange drivers, it produces a detailed and harmonious sound.
