TECHNOLOGY: SHOWCASE Large-venue loudspeakers
Covering every inch of a venue to ensure a loudspeaker system performs optimally is essential to any install. James McGrath looks at how different speaker models cope with issues such as problematic room acoustics
{ }Community Pro’s versatile R2
The R-series from Community Professional is an all-weather range of high-performance loudspeakers comprising eight models. Representing the core of
the range is the R2, which can typically be deployed in outdoor as well as indoor environments thanks to its all- weather qualities. The outer enclosure forms part of a double wall construction, with the internal bass horn acting
as the second layer, providing a completely weather-sealed chamber for the LF drivers. The R2 is available in
three symmetrical and two asymmetrical coverage patterns with 400W continuous power handling and 130-133dB maximum output. The array of coverage patterns means the range is suitable for installation in numerous locations. The system is suitable for both

certification enables audio consultants and installers to deliver a single system for information, entertainment and fire alarm systems.

{ }{ }Funktion-One widens dispersion
The d&b audiotechnik passive V-Series has been created to meet the demands of a wide range of application requirements. The Vi8, Vi12 and Vi-SUB, which differ only in mounting hardware from their live counterparts, are designed for permanent installations. With weather resistance and colour options these
line array loudspeakers can be made to blend with their surroundings, while d&b technical features ensure impressive results. The cardioid subwoofer suppresses energy towards the rear, while the two horizontal dispersion options of 80° and 120° for the three- way passive Vi8 and Vi12 respectively are controlled down to 250Hz. Constant directivity and ease of use are particular concerns at d&b; the operation of the Vi loudspeakers is simplified by a workflow comprising d&b ArrayCalc simulation software, R1 Remote control software and amplifiers. ArrayCalc predicts the electroacoustic
performance of a system in a given venue, even with curved walls, before the export function generates an R1 Remote control file. This software offers all features and functions available on the front of a d&b amplifier, and these can be remotely controlled and monitored from anywhere in the network. All settings are saved, meaning the user knows that on start-up all functions will be recalled and the system will perform consistently.

Following the launch of the MST1040 in early 2013, British loudspeaker manufacturer Funktion-One recently extended the MST (Modular Stadium Technology) Horn range with the addition of a wider dispersion option. It means the large-format loudspeaker range boasts the MST1040 (20º vertical, 60º horizontal) and the MST160 (20º vertical, 60º horizontal). The MST Horns have been designed for expansive
environments, such as arenas and stadiums, where audio performance is integral to the audience’s enjoyment and its safety.
Both models are said
to deliver excellent low- frequency dispersion control without recourse to impact-compromising delay techniques. By using MST Horns in acoustically challenging environments, sound can be focused where it’s needed, without exciting
the reverberation space. The company says such levels of control, combined with ultra- low distortion and exceptional pattern control, result in clear message transmission and intimate, intelligible and involving sound. Large waveguides that completely control all the relevant frequencies – including low-mid – enable audio to be directed solely at audience areas.
