RCF

Description

The HDL 18-AS is a compact high power line array subwoofer that complements the HDL 20-A speaker system. It is the ideal flyable bass complement for the HDL 20-A array system. The bass reflex design guarantees a deep, linear power response while the 4” voice coil vented design woofer offers the minimum of power compression.
The HDL 18-AS’s transducer feature RCF Precision ‘’Inside/Outside’’ voice coils in order to assure long-term reliability and vastly reduced power compression.

The HDL 18-AS features an 18" woofer with a 4" inside-outside voice coil and a powerful magnetic structure that guarantees a fast and accurate sub-bass frequency range. The system is powered from a 1,000-watt digital amplifier that packs huge performance operating with high efficiency into a lightweight solution. The amplifier panel is integrated to the rear central flyware. HDL18-AS amplifiers presents SMPS power supply section in order to produce maximum output and minimum transportation weight. D Line amplifiers deliver ultrafast attack, realistic transient response and impressive audio performance. The amplifier features a solid mechanical aluminum structure that stabilizes the amplifier during transportation and also assists in heat dissipation.

The integrated DSP manages equalization, soft limiter, compressor and user adjustable settings such as High pass, Low pass and phase revers. An easy to reach volume knob on the back allows to set the overall volume of the speaker according to its application. 3 status LEDs—Power/Signal/Status are provided for monitoring the system. The HDL18-AS features strong Baltic birch construction, high-quality mechanics and superior acoustic design delivering a powerful and punchy deep bass for any application. The system provides integrated mechanics compatible with the HDL 20-A array module.

The HDL 18-AS is equipped with two side aluminum handle with rubber handgrip for greater portability.
