HDL SERIES

REVOLUTIONARY LINE ARRAY

changing the concept of
large format arrays

When searching for a new touring sound system there are essential prerequisites: higher SPL’s, constant directivity and sonic excellence. In today’s competitive world rental companies are looking for more, such as reduced weight, speed of rigging/derigging and ease of transportation. And once the system is in the air, with ever decreasing venue prep times, speed of optimisation using the inherent management software is vital.

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.

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 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.

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.
