GAMMA GT25

Tweeters 1" / 2.5 cm (Pair)

Precision, control, and fine resolution up to the highest frequency ranges.

The GAMMA GT25 has been completely redesigned to meet the sonic requirements of modern, high-end vehicle systems without compromise. The focus was on extremely clean high-frequency reproduction with high detail resolution, controlled dynamics, and minimal distortion, even at high levels.

At the heart of the GT25 is the innovative carbon fiber graphene diaphragm. This material combines exceptional rigidity with an extremely low moving mass. The result is a very fast impulse response and precise reproduction of the finest details, free of harshness or sharpness in the high-frequency range.

The specially developed, pressure-relieved magnet system ensures optimal ventilation of the voice coil. This reduces thermal and mechanical compression effects, which is crucial for maintaining consistent sound quality at higher volumes. The Copper Eddy Current Brake complements this by using eddy currents to minimize distortion (THD).

Exclusive MagForce technology linearizes the magnetic flux in the drive system. Force distribution remains stable across the entire working range, which translates directly into natural, spatial, and finely resolved high-frequency reproduction.

The GT25 is designed for a high-pass filter from 2,800 Hz / 24 dB/octave. Thanks to its extensive range of accessories, it integrates flexibly into OEM positions, A-pillars, or custom installation concepts.

The GAMMA GT25 comes with a system-specific plug connector for a direct, secure link to the GAMMA crossover. This plug-and-play solution greatly simplifies installation, reduces errors, and ensures a reliable electrical connection, even in confined spaces in the vehicle.
