overview Gladen Zeta 08
The Zeta 08 is a 22-cm subwoofer driver designed for controlled, low-distortion, low-frequency reproduction. Its design emphasizes linear cone motion and stable motor behavior, making it ideal for compact subwoofer applications.
The rigid aluminum cone ensures clean, piston-like movement across the operating range, supporting accurate bass reproduction, even at higher output levels. Its robust, die-cast aluminum chassis provides high mechanical stability and features extensive ventilation to reduce air compression during operation.
The motor system incorporates integrated magnetic field stabilization to maintain consistent magnetic flux under increased drive levels. This reduces non-linear distortion, especially during larger cone excursions.
A powerful motor with a 2-inch voice coil ensures controlled force transfer in the low-frequency range. The voice coil is wound on a heavy-duty fiberglass former to reduce mechanical losses and support precise cone control.
Thanks to its large linear excursion, the Zeta 08 can deliver clean, controlled bass reproduction, even at high sound pressure levels. This makes the driver an excellent choice for applications requiring precision, control, and reliability.
