The Peavey Sanctuary Series SSE LA is a dual-radius curved line array with a dual coverage pattern (20-degree vertical, primary long throw, and 40-degree secondary short throw) comprised of 16 2in. neodymium drivers. The horizontal coverage patter is 130 degrees. An attenuation switch reduces the output of the short throw section. The frequency response is 174Hz to 18kHz with a maximum SPL of 122dB.
The Iconyx IC Live ICL-FR from Renkus-Heinz employs digital beam steering technology that provides vertical opening angles of 20, 25, and 30 degrees, and adjustable aiming angle of ± 30 degrees. Horizontal coverage above 3kHz is 120 degrees. Five 6.5in. cone drivers and three 1in. high-frequency titanium nitride compression drivers are powered by eight Class D amplifiers with integral DSP. The maximum SPL is 105dB peak and the frequency range is 80Hz to 20kHz.
RCF’s VSA 2050 features 20 3.5in. full-range drivers, each powered by its own 50W Class D power amplifier, all housed in an extruded aluminum enclosure. Onboard DSP allows the vertical coverage to be adjustable form 10 degrees to 30 degrees, and the vertical steering angle to be adjustable from 0 degrees to -40 degrees. Horizontal coverage is 130 degrees.
From SLS Audio comes the self-powered, bi-amplified Model PLS8695v2 full range line source array column. Featuring eight 6.5in. woofers and nine PRD500 ribbon tweeters, maximum calculated SPL is 130dB, and the frequency response is 70Hz to 20,000Hz with a selectable 80Hz high pass filter. The horizontal coverage is 120 degrees.
Tannoy’s VLS 30 comprises 14 3.5in. woofers and 16 1in. metal-dome tweeters mounted in a 57.5in. tall extruded aluminum enclosure. The loudspeaker incorporates Focused Asymmetrical Shaping Technology (FAST) that provides asymmetrical vertical coverage. The horizontal coverage is 130 degrees. The peak output is 126dB SPL, and the frequency range is 90Hz to 35kHz.
TOA Electronics’ SR-H2 series features the L and S models, each with nine 2.8in. cone drivers. Both models feature 90-degree horizontal coverage. Vertical coverage for the L is equal to the height of the loudspeaker and the S provides vertical coverage of 20 degrees, using a hyper-clothoid concept curved array. The frequency response for the L is 80Hz to 18,000Hz versus 90Hz to 17,000Hz for the S.
