Gladen Zeta 08 subwoofer

Gladen Zeta 08 subwoofer

The Zeta line represents the pinnacle of Gladen's technical approach to car audio, emphasizing maximum accuracy, control and reproduction fidelity. Zeta subwoofers were developed as a natural extension of this concept toward the lowest frequencies. They are not aimed at short-term maximum acoustic pressure, but at deep, accurate and stable bass that integrates smoothly with quality front systems and supports the overall sound without unnecessary dominance. Low distortion, high control and musicality are the fundamental pillars of the entire Zeta subwoofer range.

Long-throw motor and 2" voice coil

The ZETA 08 subwoofer uses a powerful long-throw motor system designed for stable and precise operation even at larger cone excursions. The aerodynamically optimized 2" voice coil is wound on a robust fiberglass former that minimizes mechanical losses and increases overall motion efficiency. This design allows very accurate control of the cone and maintains linear behavior across the operating range. Thanks to the large linear excursion the subwoofer preserves control, quick response and low distortion even at higher volumes and during dynamically demanding passages.

Aluminum cone

A stiff aluminum cone was chosen to maximize piston-like motion and mechanical stability when reproducing deep frequencies. Due to its stiffness and low deformation it contributes to accurate and readable reproduction of the bass band even under higher loads. The stable aluminum pressure basket provides a solid foundation for the driver and is designed with effective ventilation. This reduces air compression, improves cooling and contributes to consistent behavior of the subwoofer during long-term use. The result is high mechanical durability and long life without loss of sonic properties.

Magnetic system

The subwoofer's magnetic system is equipped with integrated magnetic field stabilization aimed at maintaining a constant magnetic flux even at higher cone excursions. This solution significantly reduces nonlinear distortion that commonly occurs under high motor load. Thanks to the stable magnetic field the cone movement is more precise, better controlled and more readable even at the lowest frequencies. The result is bass with higher definition, better dynamics and a more natural character without undesired artifacts.

Wiring flexibility and compact installation

The Zeta 08 is equipped with dual 2 Ohm voice coils, providing high flexibility in wiring design and allowing optimal matching to power amplifiers. This makes it easy to combine the subwoofer with powerful amplifiers in various configurations. The driver's optimized parameters allow use in both sealed and ported enclosures, while the subwoofer maintains control even in smaller volumes. This makes it ideal for demanding installations with limited space where the priority is sound quality rather than just bass quantity.
