Combining the properties of a horn-loaded, constant or variable curvature array, while meeting specifications for high vocal intelligibility, was the design goal set by RCF when producing the new medium- to long-throw HL series for stadium and arena use. The product was previewed at the 2013 InfoComm show and is now in production. The new two-way passive HL2240, HL2260, HL2290 full range, and HS2200 subwoofer are additions to the Italian company’s Installed Sound System catalog. The series was inspired by a recent stadium installation and a large-scale vocal reinforcement project. The customer requirement was for a constant curvature array with the specific key point of vocal reproduction. To achieve this curvature, the perfect balance was found between a line array solution and a small system made up of several loudspeaker components. Within the product nomenclature, the ‘22’ designates the 22.5-degree horizontal coverage pattern of each loudspeaker, and the 40, 60 and 90, respectively, the vertical angles. All speakers are bass-reflex horn-loaded, symmetrically designed, with the horn in the center. The full-range speakers each house 4in. horn-loaded compression driver and 2 x 12in. horn-loaded sub. The 1 x 18in. HS2200 subwoofer has been designed as the complement for LF extension. The connectors are IP67-rated and the enclosures, constructed in Baltic birch plywood, are finished in Polyurea to make them IP55-rated weather resistant. The different coverage angles are defined in the RCF engineering, which enables the sound beams to be focused differently.
