RCF HDL 38-AS - 3200W 18-inch Powered Flyable Subwoofer with RDNet and 4-inch Voice Coil in Black Finish

The RCF HDL 38-AS is a powerful and compact flyable subwoofer designed to complement the RCF HDL 30-A array system, providing deep, extended bass performance for a wide range of applications, including theatrical events, live sound, and installations. With a robust 3200W peak Class-D amplifier, the HDL 38-AS is capable of producing up to 136 dB SPL, delivering clean, distortion-free bass from 30 Hz to 140 Hz. The subwoofer is powered by a state-of-the-art 18-inch neodymium woofer with a 4.0" voice coil, ensuring maximum linearity and minimal distortion even at high output levels. This combination of high-performance components makes the HDL 38-AS an ideal choice for flown systems in both indoor and outdoor venues.

One of the standout features of the HDL 38-AS is its compatibility with RDNet, RCF's advanced remote monitoring and control system. RDNet allows for intuitive control over every connected device in the RCF audio system, providing real-time monitoring, adjustments to levels, delay, EQ, and advanced subwoofer configurations. This networked management system ensures seamless integration with other RCF devices, such as digital matrixes and amplifiers, making it perfect for complex installations and large-scale events. RDNet also enables fine-tuning of system parameters, ensuring optimal performance in a variety of environments and applications.

The HDL 38-AS utilizes RCF's latest advancements in transducer technology, including cutting-edge neodymium magnetic circuits, innovative voice coil ventilation systems, and direct-drive voice coil assemblies. These developments ensure exceptional sound quality, efficiency, and durability. The Class-D amplifier technology provides ultra-fast attack and realistic transient response, with an incredibly high signal-to-noise ratio. The amplifier is housed in a solid machined aluminum structure that aids in heat dissipation, eliminating the need for a cooling fan and contributing to the system's lightweight design. The system also features SMPS (Switch Mode Power Supply), which optimizes efficiency while minimizing weight.

Designed for ease of use, the HDL 38-AS is equipped with integrated rigging hardware, allowing for quick and reliable setups. The subwoofer is fully compatible with the HDL 30-A rigging system, enabling flexible array configurations. The heavy-duty front grille is powder-coated for durability, and a transparent-to-sound foam backing inside the grille helps protect the transducers from dust. For outdoor and weather-sensitive applications, an optional rain cover is available to protect the system in harsh conditions.

Whether used in conjunction with the HDL 30-A or as part of a larger sound system, the RCF HDL 38-AS delivers the power, clarity, and low-frequency response necessary for creating immersive sound experiences at large-scale events. With its advanced DSP processing, RDNet compatibility, and high-output capabilities, the HDL 38-AS is the perfect choice for demanding sound reinforcement applications that require reliable, high-performance bass.
