Description

The RCF HDL 28-A is a compact bi-amped 2-way 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.

Why active?
The HDL System is composed of HDL 30-A and HDL 50-A, equipped with modern and innovative technology. Each component has been consistently and specially developed by RCF’s experienced engineering teams, with all components carefully matched to each other. This complete integration of all components allows not only superior performance and maximum operational reliability, but also provides users easy handling and plug & play comfort. Besides this important fact, active speakers offer valuable advantages: while passive speakers often need long cable runs, the energy loss due to the cable resistance is a huge factor.
This effect is irrelevant in powered speakers where the amplifier is just a couple of centimeters away from the transducer. An active sound reinforcement system means more than just having amplifiers packed into a speaker housing. The real innovation is when each single component is controlled by individual DSP settings. Scaling a line array is the most important aspect when talking about best performance and coverage.
Where passive systems have limits in impedance load or number of amplifier channels, an active RCF sound system is freely scalable and individually controllable. Having an HDL system gives you the freedom to work at many different locations with the same system, merely changing the number of modules.
The transducers innovators
The RCF loudspeaker line incorporates a vast range of transducers covering the entire audio spectrum. We design our transducers to optimise the relationship between the purity of sound, combining the absence of distortion and the ability to withstand high power levels over a long period of time.
RCF develops advanced transducer technology including the application of high-tech materials such as Neodymium, Carbon Fibre, Pure Titanium, Kevlar, Kapton and Mylar hybrids. With over 70 years of design and manufacturing experience in the market.
RCF has been instrumental in technological inventions such as: carbon fibre cone moulding, double silicon spiders, inside/outside voice coil windings to edge wound voice coil manufacturing and pure titanium diaphragm forming. 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.

Dual silicon spiders
RCF’s original invention of the dual silicone sealed spider design offers many advantages: the two spiders offer double resistance to fatigue. The silicone between the cloth layers, being a very high memory material, provides the best shape stability to the spiders. The system, being sealed, functions as an air pump expelling hot air and drawing in cool air every time the cone assembly moves.

Custom designed waveguide
RCF has developed a unique voice coil, combining the advantages of inside/outside technology to the superior quality of polyimideimide materials (wire resins and formers resins). The inside/outside coil offers many advantages:

  • The dissipation surface is doubled
  • The adhesion area to the former is doubled
  • During thermal expansion the Former is squeezed between inside and outside layers offering the best mechanical resistance.

 

Complex hyper-venting coolings
In our complex cooling designs individual components come together to create an ideal ventilation system. Finned cooling channels dissipate heat efficiently, the dust cap and the sealed spiders function as an air pump, expelling hot air and drawing in cool air every time the cone assembly moves. Many openings are situated directly on the transducer’s side and on the rear plate.

Custom high frequency waveguides
The HDL custom 4PATH designed waveguide allows precise coverage of 90 x 10 degrees (HDL 50-A) and 100 x 15 degrees (HDL 30-A), while also delivering a superb, linear high frequency response. The unique shape of the four ducts forming the guide creates an ideal isophasic load from the crossover frequency to the highest audible frequencies.

Direct drive voice coil assemblies
The top of the former is bent and bonded directly to the edge of the titanium diaphragm resulting in a Direct Drive configuration. Direct Drive guarantees optimal transfer of energy between the voice coil and the dome assembly, providing smoother, extended frequency response beyond 10 KHz, reducing break up modes and lowering distortion. This assembly delivers high power handling along with excellent mechanical and thermal properties that make RCF neodymium compression drivers robust and reliable.
