Gladen Zeta 10

The Gladen Zeta 10 is a high-quality 25 cm (10-inch) subwoofer designed specifically for powerful, precise, and low-distortion bass reproduction. With a power handling capacity of 300 watts RMS, a maximum power output of 600 watts, and a 2 x 2-ohm dual voice coil, it provides an excellent foundation for high-end car audio systems.

The exceptionally rigid aluminum cone allows for controlled cone movement even at high excursion levels, while also promoting heat dissipation. Together with the optimized NBR surround and the durable CONEX centering spider, it ensures high mechanical durability and precise bass reproduction.

The sturdy, fully vented die-cast aluminum basket reduces unwanted air compression and airflow noise. Additional ventilation openings near the diaphragm neck improve cooling and help ensure low-distortion sound reproduction even at high volumes.

The high-performance magnet system, featuring a 145-mm magnet diameter, two integrated aluminum short-circuit rings, and a four-layer 50-mm voice coil, ensures excellent drive control. The short-circuit rings reduce magnetic field-induced distortion, while the long-throw design with a ±11.5 mm linear excursion enables dynamic and deep bass reproduction.

Thanks to its well-thought-out design, the Gladen Zeta 10 is suitable for both compact sealed enclosures starting at 17 liters and bass-reflex enclosures with a volume of approximately 35 liters. This makes it the ideal choice for sound-oriented car audio systems where depth, precision, and power handling are paramount.
