The integrated Crossover at 3.5 kHz allows for a clean and homogeneous sound image. With an impedance of 3 Ohm and an efficiency of 93 dB, the system can be efficiently operated with car radios or amplifiers. It is designed for easy integration into various vehicle types without extensive modifications. With its outstanding sound performance, the Speaker Set offers a clear improvement over standard sound systems.

The GLADEN BETA 165.2 is a 2-way component system designed for precise and natural sound reproduction in vehicles.
It represents an evolution of standard speakers and is positioned within the GLADEN range between Alpha and Gamma. The focus is on balanced tuning and controlled acoustic performance in everyday use.

The 165 mm mid-bass driver works with a classic paper cone. This material is characterized by very good damping behavior and allows for clean, colorless reproduction in the midrange.
At the same time, the combination of cone, surround, and drive ensures a structured and controlled fundamental and bass range.

The 25 mm fabric tweeter complements the system with a uniform and finely resolved high-frequency reproduction.
Thanks to the tuned 12 dB Crossover at 3.5 kHz, a clean transition between the individual frequency ranges and a closed, homogeneous sound image is created.

With an impedance of 3 Ohm and an efficiency of 93 dB|2.83V dB, the system is designed for efficient operation.
This allows the BETA 165.2 to be used both directly with the car radio and in combination with compact amplifiers. Even under these conditions, it offers a significant sound improvement over OEM systems.

The construction is designed for practical integration and allows for use in many vehicle-specific installation situations without extensive modifications.
