The HDL 28-A from RCF is a dual 8” powered line array speaker with two 8” woofers and a 3” titanium compression driver. This compact bi-amped 2-way active touring system offers great acoustical power in a lightweight, easy-to-handle build. Whether temporarily set up or permanently flown, the HDL 28-A is great for a wide range of applications, both indoors and outdoors, with an emphasis on vocal intelligibility.
Other features include its time coherent waveguide, state-of-the-art RCF transducers with neodymium magnets, and composite cabinet with zero-degree phase and ultra-linear amplitude response. In addition, its 2200W class-D amplifier delivers excellent playback clarity and up to 135 decibels SPL max.
More about RCF’s HDL Powered Line Array Systems
Using modern and innovative technology to enhance flexibility and functionality, HDL is RCF’s series of powered line array speakers and subwoofers. Perfectly scalable and equipped for professional applications including live sound rental companies, HDL incorporates transducers to optimize audio purity, reduce distortion, and enhance power handling levels.
Great for venues small and large, HDL features RCF’s innovative dual silicone spider design for maximized stability and increased cooling ability for better ventilation. Meanwhile, RCF’s unique voice coil design is constructed with superior quality. HDL’s custom 4PATH-designed waveguide allows precise coverage while also delivering a superb, linear high-frequency response.
The HDL series also offers a Direct Drive configuration to guarantee optimal transfer of energy between the voice coil and dome assembly to achieve a smoother, more extended frequency response beyond 10KHz while minimizing distortion and breakup modes. These line array speakers deliver high power handling and the excellent mechanical and thermal properties that make RCF’s neodymium compression drivers robust and reliable. Their RDNet Networked Control functionality enables the best listening experience at any venue.
