HDL 28-A
ACTIVE TWO-WAY LINE ARRAY MODULE
DESCRIPTION
The RCF HDL 28-A is a compact bi-amped 2way active touring system for a wide range of
applications, both indoors and outdoors, with
an emphasis on vocal intelligibility. It features
two 8-inch woofers and an impressive 3-inch
titanium compression driver. The time
coherent waveguide is the result of in-depth
research and design. Following the HDL 30-A
philosophy, the HDL 28-A shares the
composite material cabinet, the zero-degree
phase and ultra-linear amplitude response.
The built-in 2200 watt class-D amplifier
delivers excellent playback clarity and up to
135 decibels SPL max. The RCF HDL28-A
features state of the art RCF transducers with
lightweight neodymium magnets. Considering
its acoustical power, it has a remarkably low
weight for easy handling and flying.
The HDL 36-AS is the ideal flyable bass
complement for the HDL 28-A array system.
