Zeta 10

Discover the Gladen Zeta 10, a 10" (25 cm) Subwoofer, known for its outstanding sound quality and impressive performance. This Subwoofer delivers powerful bass reproduction and is perfect for precise tones and impressive acoustics. It impresses with its high level stability and low distortion, while its aluminum diaphragm and long-stroke drive system ensure effective heat dissipation and stable cone movement. With a robust aluminum die-cast basket and a dual 2-ohm voice coil, the Zeta 10 allows for flexible system concepts and minimizes airflow noise. Thanks to the optimized outer suspension and Conex spider, this Subwoofer offers consistent performance and durability. Ideal for sealed enclosures starting from 17 liters.

The Zeta 10 is a powerful 25 cm Subwoofer chassis designed for high level stability, low distortion, and long-lasting durability. Its construction is consistently focused on controlled diaphragm movement and thermal stability.

The extremely stiff aluminum diaphragm ensures clean cone movement even at high excursions and simultaneously supports effective heat dissipation under high continuous load. A newly developed, optimized outer suspension complements this and ensures secure guidance of the diaphragm during large strokes.

The reinforced aluminum die-cast basket is fully ventilated and offers high mechanical stability. Additional venting openings in the area of the diaphragm neck reduce air compression and contribute to low-distortion reproduction. The low airflow speed in the basket area minimizes audible airflow noise.

The drive system features two integrated aluminum short-circuit rings that stabilize the magnetic field and significantly reduce distortion at high levels. The oversized motor with a 2-inch voice coil and 145 mm magnet ensures high control and efficiency.

The voice coil is built on a robust fiberglass carrier, reducing mechanical losses. This improves both dynamics and the reproduction of fine details at low levels. A 4-layer voice coil further increases control and allows for use in compact enclosures.

The linearly designed centering spider made of CONEX material ensures a long lifespan and consistent performance, even under extreme operating conditions. The long-stroke motor design allows for high linear excursions with low distortion.

Thus, the Zeta 10 is the ideal foundation for high-quality Subwoofer systems where precision, durability, and control are paramount.
