The GT 8 is a versatile point source speaker engineered for precise sound coverage in high-powered professional audio applications. Its enclosure is constructed from durable, highquality marine-grade plywood, housing two 8” neodymium woofers in a symmetrical configuration and a central 3” titanium-dome neodymium compression driver mounted on a rotatable magnetic constant-directivity TRW waveguide. The magnetic grille allows for easy waveguide rotation without tools, with easy inspection of the orientation from a lateral window. For scalable, high-performance sound reinforcement and a perfect match with GTX signature sound, it integrates seamlessly with XPS 16K amplifiers, supporting up to three speakers per amplifier channel or two speakers for high-performance output.

HIGH-PERFORMANCE ACOUSTIC DESIGN

Developed using Finite Element Analysis and validated in TT+ Audio’s anechoic chambers, the GT 8 incorporates the innovative TRW (True Resistive Waveguide) to deliver efficient driver loading and precise pattern control. Its phase-coherent symmetrical arrangement of the cone transducers ensures optimal time alignment, while the passive crossover network is finely tuned to maximize dynamic response across frequency bands. Leveraging FiRPHASE optimization via the XPS amplifier’s internal DSP, the transducers' radiation combine and emerge as a single 0º linear phase wavefront. This significantly minimizes off-axis distortions, enhancing clarity and delivering outstanding performance over the entire frequency range.

BUILT FOR HEAVY TOURING

GT 8 is built to endure the rigors of touring, featuring a robust plywood cabinet coated with a durable polyurea finish that provides exceptional waterproofing and scratch resistance. Ergonomic die-cast aluminum handles with rubber grips on the top and bottom ensure comfortable and secure handling. A magnetically detachable grille enables quick access to the internal components, while the rotatable TRW waveguide—secured by a high-force magnetic assembly—can be adjusted without tools. A side inspection window allows easy verification of the selected coverage pattern. Quick-Fit M10 sockets on the top and bottom provide integration with various accessories, including horizontal and vertical brackets, subwoofer stack mounts, and pole mount adapters. The connection panel features two SpeakON STXX Series 4-pole IP54 heavy-duty metal connectors.
