The GTS 16C is a high-performance flyable cardioid subwoofer, ideal for installations demanding impactful low-frequency performance with controlled dispersion. Built with a high-quality plywood cabinet, it features a 16” neodymium front woofer and a 14” neodymium rear woofer. With integrated suspension hardware, the GTS 16C can be quickly flown or stacked. Equipped with two SpeakON STXX Series 4-pole IP54 heavy-duty metal connectors and capable of cascading up to three modules per XPS 16K channel, it provides reliable and powerful low-frequency output for professional environments. DIRECTIONAL SUBWOOFER Low frequencies are naturally omnidirectional, which can lead to unwanted energy buildup on stage, excessive reverberation in enclosed spaces, or noise pollution in open-air environments. A cardioid subwoofer, whether ground-stacked or flown, solves these issues by focusing bass energy towards the audience while significantly reducing rearward sound emissions. This targeted dispersion enhances clarity, improves low-frequency impact, and minimizes interference with microphones and stage monitors. By implementing active cardioid technology provided by TT Audio DSP processing, the GTS 16C delivers controlled, high-output bass exactly where it's needed. 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. 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. POLYUREA COATING ADVANTAGES All TT AUDIO enclosures are finished with a highly durable polyurea coating that provides excellent waterproofing and corrosion protection and withstands abrasion, impacts, and mechanical stress. Its extreme elasticity maintains flexibility even in low temperatures – perfect for enclosures prone to vibrations such as high-power subwoofers. It also exhibits strong chemical resistance and does not emit any VOCs (volatile organic compounds), making it environmentally friendly and safe for human health. ENCLOSURE AND RIGGING Housed in a high quality plywood, polyurea-coated enclosure, the GTS 16C features two SpeakON STXX Series 4-pole IP54 heavy-duty metal connectors. It supports cascading up to six modules with one XPS 16K amplifier unit. Designed for unparalleled adaptability, it excels in acoustically challenging environments. Featuring optimized hardware for suspension, two aluminum handles per side with rubber handgrips ensure easy handling.
