The RCF HDL 38-AS is the ideal flyable bass complement for the HDL 30-A array system. It features one 4.0” voice coil, 18” Neodymium woofer to handle 136 dB SPL Max from 30 Hz to 140 Hz with maximum linearity and low distortion. The HDL 38-AS is perfect to create flown systems for theatrical and indoor requirements. The built-in 3200W class-D amplifier delivers excellent playback clarity and up to 136 decibels SPL max. Due to its compatibility with RDNet – remote monitoring and control, the HDL 38-AS is part of the professional HDL System.

NETWORKED CONTROL AND MUCH MORE
RDNet is a robust management network and control platform for small, medium, and large arena-sized sound systems, as well as complex and extended installations. Based on a proprietary network protocol, RDNet provides intuitive control and monitoring of every connected device/object in the RCF audio system. Each device has DSP to address specific presets or modifications of parameters to single or groups of objects. A network user can change level, delay, EQ (linear phase FiR as well) and other settings, including advanced subwoofer configurations. RDNet is not only designed for loudspeakers—you can control parameters and routing of multiple RCF devices, such as digital matrixes or amplifiers.
POWERFUL CLASS-D AMPLIFIERS
RCF’s Class-D power amplifier technology packs huge performance operating with high efficiency into a lightweight solution. HDL amplifiers deliver ultra-fast attack, realistic transient response, and impressive audio performance. The amplifier features a solid machined aluminum structure which not only stabilizes the amplifier during transportation but also helps the fan-less heat dissipation. All the HDL amplifiers present SMPS power supply section to produce maximum output and minimum weight.
Our latest developments have resulted in designing state of the art neodymium magnetic circuits, radically new voice coil ventilation systems, and ground-breaking direct drive voice coil assemblies.
CABINET AND MECHANICS
The hardware is designed for an easy and fast setup, completely compatible with the HDL 30-A rigging. The heavy-duty front grille is powder-coated. A special transparent-to-sound foam backing inside helps to further protect the transducers from dust. For weatherproof capabilities, a rain cover is available.
