The GTX 7C is an advanced line array module engineered for precise, high-performance sound reinforcement in demanding applications. Featuring digitally controlled directivity, it surpasses traditional cardioid solutions by integrating advanced acoustical design with active DSP optimization. The front and rear speakers are independently powered through separate audio channels, with extensive digital processing provided by the XPS power amplification platform. Each module achieves an average rear attenuation of 22 dB up to 600 Hz and a maximum SPL of 140 dB. An onboard, passive, phase-optimized crossover at 900 Hz ensures seamless frequency distribution while FiRPHASE and BMC processing deliver precise attenuation in a broader frequency range than competing systems. Available in full black or white coating. HIGH-PERFORMANCE ACOUSTIC DESIGN GTX 7C incorporates a Linear Resistive Waveguide to deliver efficient driver loading and precise pattern control. Its phase-coherent symmetrical arrangement of the cone transducers ensures optimal time alignment. At the same time, the onboard passive crossover network is finely tuned to maximize dynamic response across frequency bands and optimize phase. 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. ACTIVE CARDIOID TECHNOLOGY While the physical configuration of woofers in traditional cardioid designs provides basic rear sound cancellation, it is often constrained by specific frequency limitations and relies on a passive approach—using a single or pair of transducers driven from the same audio channel. In contrast, TT Audio's active cardioid systems feature independently driven front and rear speakers with extensive DSP capabilities. This active configuration provides several key advantages: Ideal Primary Cardioid Attenuation Because front and rear transducers are driven separately, speaker placement can be optimized to achieve the best possible acoustic cardioid cancellation. Precise Rear Wave Rejection Speakers are digitally and dynamically aligned to perfectly cancel rear wave propagation, achieving up to 30 dB front-to-rear rejection levels. Independent Limiters and Protections This ensures maximum output with minimal distortion and allows each driver to operate at its optimal performance level. Wider Frequency Range of Cardioid Radiation By adopting FiRPHASE technology, the cardioid effect is extended across a wider frequency range while achieving 0º linear phase response. FORWARD-THINKING: PUSHING SOUND WHERE IT MATTERS Front-to-rear rejection of 20 to 30 dB, minimizing unwanted noise on stage. Reduced interference with reflective surfaces like walls and buildings. Reduced microphone bleed for cleaner stage sound. Wider frequency range attenuation, powered by FiRPHASE and BMC processing. Independent excursion limiters and protections, ensuring maximum output and system reliability. PRECISION TRANSDUCERS At TT AUDIO, we maintain full control over the design, engineering, and manufacturing of each component, subjecting them to rigorous testing—including 200 hours of continuous musical signals under extreme conditions. TT Audio adopts large format compression drivers for the HF of our products, engineered to withstand lower crossover points than our competitors. This approach offers several advantages: The overall efficiency of the system is improved, resulting in a higher maximum SPL. The range controlled by the horn directivity is extended. Clearer vocal reproduction due to the crossover point. Rear attenuation is improved and distortion at MF is reduced. Linear Resistive Waveguide Our proprietary Linear Resistive Waveguide (LRW) provides broadband directivity and a flat hemicylindrical wavefront. The crossover operates before rear attenuation, ensuring a smoother transition with the woofers' radiation. HIGH FREQUENCY The 4-inch titanium dome compression drivers, equipped with high-current neodymium magnets, are designed to fully leverage the remarkable capabilities of the TRW-4PATH waveguide. As a result, the GTX 7C 120° x 10° coverage is finely matched with the output of its woofers for perfect phase coherence. ENCLOSURE AND RIGGING HARDWARE Housed in a shock-absorbing, polyurea-coated enclosure, the GTX 7C features two SpeakON STXX Series 4-pole IP54 heavy-duty metal connectors. It supports cascading up to four modules with two XPS 16K amplifier channels. Designed for unparalleled adaptability, it excels in acoustically challenging environments. Featuring optimized hardware for suspension, two rear and two side aluminum handles with rubber handgrips ensure easy handling.
