RCF TTS 18-A II - 1100W 15-inch Powered Bass Reflex Subwoofer with RDNet and 3-inch Voice Coil in White Finish

The RCF TTS 18-A II is a high-performance, compact subwoofer designed to deliver exceptional low-frequency reproduction for a wide range of professional audio applications. Ideal for use with TT+ two-way systems, the TTS 18-A II is a powerful subwoofer module that excels in both indoor and outdoor environments. It features a 18-inch woofer with a lightweight neodymium magnet and a 4-inch voice coil, providing excellent power handling and minimal power compression. The subwoofer's efficiency is further enhanced by the use of silicon double spiders and a water-resistant treated cone, ensuring durability and consistent performance even under demanding conditions.

At the heart of the TTS 18-A II is a 1400W RMS Class-D amplifier, which integrates a low-noise 32-bit DSP circuit for precise control and optimization of the subwoofer's performance. The amplifier offers soft clipping limiters, RMS limits, polarity adjustment, amplitude control, and equalization, all of which are easily accessible via the RCF RDNet network management platform. RDNet provides real-time monitoring and remote control capabilities, allowing for easy integration into large-scale sound systems. Users can adjust levels, delays, EQ settings (including linear phase FiR), and subwoofer configurations, making the TTS 18-A II an ideal choice for dynamic sound reinforcement needs.

The TTS 18-A II subwoofer is built with a high-quality Baltic birch plywood cabinet, which is coated with a durable polyurea finish for weatherproofing and enhanced longevity. This rugged cabinet is designed to withstand the rigors of touring and extended use. The subwoofer also features a vented port system, which is engineered to reduce airflow turbulence and improve efficiency. The laminar airflow design minimizes distortion and ensures that the subwoofer produces clean, tight bass even at high volumes.

To ensure optimal placement and versatility, the TTS 18-A II is equipped with M20 pole receptacles on both the top and side of the cabinet, allowing for both vertical and horizontal positioning. The subwoofer can be easily integrated into stacked or flown systems and is particularly effective when paired with other TT+ components for a complete sound reinforcement solution. The unit is lightweight and features rubber feet on two sides, making it easy to transport and set up. Additionally, the subwoofer can be rigged with ease using the M20 pole mounts and stabilizing brackets, which ensure secure vertical placement.

For maximum portability, the TTS 18-A II is equipped with handles on both sides, making it easy to move and position. The unit also comes with RDNet support for remote monitoring, offering flexibility in large-scale installations. The subwoofer's DSP-controlled input section includes selectable presets, such as cardioid configuration, and allows for easy integration with the rest of the system. With a frequency response of 30 Hz to 400 Hz and a maximum SPL of 137 dB, the TTS 18-A II is more than capable of providing powerful and consistent low-end performance for a variety of professional sound applications.
