Gladen SIGMA 22

The Gladen SIGMA ST 22 is a high-quality 22 mm silk dome tweeter that impresses with its precise high-frequency reproduction, excellent detail resolution, and high dynamic range. Thanks to its compact design and innovative modular installation system, it is ideal for high-end car audio installations as well as integration into factory speaker locations.

The high-quality silk dome enables natural, balanced, and finely detailed reproduction of high frequencies. The integrated rear coupling chamber facilitates particularly deep coupling with the low-midrange driver, while the excellent omnidirectional dispersion ensures even sound distribution throughout the vehicle interior.

Thanks to its flexible mounting system, which includes various mounting rings, adapters, and grille covers, the SIGMA ST 22 offers a wide range of installation options. Whether in the mirror triangle, the A-pillar, or in original mounting locations—the tweeter offers an ideal combination of sound quality, compact design, and high installation flexibility.
