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.

GTS 16C adopts a dual-woofer, dual-amplified architecture engineered to deliver controlled cardioid performance at low frequencies. The 16” neodymium front woofer provides the primary forward output and impact, while the 14” neodymium rear woofer is purpose-designed to generate the opposing rear wave required to attenuate emission behind the enclosure.

Both transducers are optimized for high linear output with low distortion. Lightweight aluminum-core voice coils, high-damping cellulose cone material, composite spiders, and a 4-layer inside-outside coil design enable ultra-long excursion and fast acceleration under high power. TT+ Audio Hypervented cooling further limits thermal buildup, reducing power compression and distortion to maintain stable, repeatable performance under sustained high-level operation.

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.

BUILT FOR GTX 7C CARDIOID ARRAY

Engineered as the dedicated low-frequency partner for GTX 7C arrays, GTS 16C integrates into the same cardioid system concept and shared rigging ecosystem for predictable results in flown or stacked deployments. GTX 7C is a compact cardioid line array module with digitally controlled directivity, designed to go beyond traditional cardioid approaches by combining acoustical design with active DSP optimization. Its front and rear radiating sections are independently powered on separate amplifier channels, with extensive digital processing managed by the XPS amplification and DSP platform, enabling consistent pattern control and significant rear attenuation across scalable array configurations.
