By PSW Staff • September 30, 2012 Take our our Photo Gallery tour of a wide range of compact line array options from around the industry In this Real World Gear installment, we look at compact line arrays, which we’ve defined as those with 8-inch (and smaller) LF drivers. Generally speaking, products in this genre offer a relatively small footprint in terms of size, weight and cost. They’re conveniently portable due to the size/weight factor, but are suitable for fixed installations as well. For dynamic full-range music presentation, compact arrays are usually accompanied by at least one subwoofer. In addition, the vast majority of full-range models are joined by companion subwoofers, many of them designed to fit seamlessly within a flown array structure. Further, compact arrays present a scalable solution – a single unit will provide main coverage to a relatively small space, but with the addition of more loudspeakers, coverage capabilities are easily expanded, and at an affordable level. Some manufacturers also engineer array modules of various sizes to work together. Most commonly, we see compact modules at the bottom of larger arrays, providing commensurate front fill coverage at concerts, festivals and other large-scale events. An ever-expanding selection of line array tools can only serve to enhance the craft. The challenge is knowing what’s available and being able to quickly differentiate them, at least from a specification standpoint. And that’s the point of Real World Gear – enjoy our Photo Gallery tour of a wide range of options from around the industry. In addition to our tour, note the following additional information on several models. NEXO GEO S8 NEXO GEO S8 line array loudspeakers are at the center of a multi-million dollar renovation of the 3,100-seat Township Auditorium in Columbia, SC. Sid Gattis of Gattis Pro Audio, also in Columbia, designed and installed the audio system centered around GEO S8 and CD12 subwoofers. (click to enlarge) “The GEO S8s are insane,” Gattis notes. The loudspeakers are processed with three NX242 processors and hung on custom steel mounts. Designed and built by Gattis Pro Audio crew chief Scott Shealy, the mounts come through the wall to stage left and right. “Once we checked aiming with GeoSoft, we fired up the system, and I can tell you there’s not a bad seat anywhere, not even in the first or second balconies,” states Gattis. “The top seat in the house is as clear as the 10th row. Everyone is amazed that these little boxes can do so much. “The NEXO system is one of the most advanced products in the world, and the sound quality is absolutely phenomenal.” Go here for more about the GEO S8. QSC Audio WideLine-8 WL3082, WL3082-wx Throughout the summer months in Jackson, MO, the Jackson Municipal Band plays free concerts every Thursday evening. (click to enlarge) To insure that the band sounded better than ever for its 92nd season, local systems integrator Unity Pro Audio and Video upgraded the Jackson Municipal Bandshell in City Park with a six-cabinet QSC Audio WL3082-wx Weatherized WideLine-8 line array powered by three QSC PowerLight 3 Series amplifiers and optimized with an SC28 System Controller. Matt Schwartz of Unity Pro AV determined that the optimum solution for the bandshell, which is approximately 50 feet wide, was a center array with a wide dispersion pattern, and then selected WideLine-8, citing its ample coverage and affordable price point. “When I compared other weatherized speakers, in terms of price and power, everything pointed to QSC. I’d heard the WideLine System before and I knew it packed a punch. It’s a great system,” says Schwartz. (The coverage area and array are shown in the photos.) Go here for more about the WideLine-8. Adamson Systems Metrix Metrix is equally well-suited for installation and touring applications, complete with two rigging system options, and it also excels as an under hang, side, front and balcony fill cabinet. (click to enlarge) Metrix delivers clean and even coverage, with a surprisingly high SPL. The lighting-fast rigging can be performed by a single person. Metrix is designed for use in arrays of six or more elements; each enclosure has a 120-degree (h) by 5-degree (v) coverage pattern. A system recently implemented at the 600-capacity sanctuary of Campbellsville (Kentucky) Baptist Church features coverage provided by two arrays, each comprised of eight Metrix enclosures and two Metrix W (15-degree trapezoidal) cabinets. One Metrix Sub is positioned on each side of the floor, joined by a single flown Metrix Sub. “The sound results far exceeded already high expectations,” says Ryan Jackson JCA Media, which provided the design and install. Go here for more about Metrix. JBL Professional VerTec VT4886 Featuring two 6.5-inch Differential Drive low-frequency transducers, four 2.5-inch midrange transducers and two 1-inch-exit compression drivers, the JBL Professional VerTec VT4886 is a true 3-way design that is unique to the subcompact line array category and has the highest component power density and SPL output in its class. (click to enlarge) A proprietary mid/high frequency waveguide assembly seamlessly integrates MF and HF section output in a next-generation implementation of JBL’s patented R.B.I. (Radiation Boundary Integrator) technology, providing precise wavefront control and allowing for proper vertical coupling from 0 to 15 degrees. The waveguide/RBI developed for JBL’s recently-released VTX V25 enclosure shares similar design attributes as the device employed in VT4886. The LF transducers are matched to a low-frequency diffraction absorber with a tuned resonant-chamber that reduces cavity resonance and cabinet edge diffraction effects. Go here for more about the VerTec VT4886. D.A.S. Audio AERO 8A Earlier this year, BamaJam 2012 fired up the area just north of Enterprise with lights, video displays, and music. Located on the 1,600 acre grounds of BamaJam Farms, 35,000-plus music enthusiasts from all over the southeastern United States converged and reveled to the sounds of Tim McGraw, Zac Brown Band, Sheryl Crow, Kid Rock, and a long list of additional artists. (click to enlarge) Smyrna, TN-based Allstar Audio Systems was contracted to handle all staging, sound, lighting and backline for this year’s festival. “From an audio perspective, this year’s BamaJam festival was huge,” notes Mike Borne, president and founder of Allstar Audio. “We had two-plus semi-trucks loaded with audio gear just for the main stage. “D.A.S. Audio loudspeaker systems served as the house mains for each of the three stages, and 12 D.A.S. Aero 8A powered, ultra-compact line array speakers were used for out fills.” Go here for more about the AERO 8A. Martin Audio W8LM Commissioned to provide sound and technical production for the unveiling of the Cutty Sark in London’s Greenwich, following an extensive restoration, SXS equipped the stage in Cutty Sark Gardens with its new Martin Audio W8LM line array system, comprising 12 enclosures in two hangs, with two W8LMD Downfills at the base of each hang. (click to enlarge) Attended by the Queen and the Duke of Edinburgh, the event included a 90-strong symphony orchestra and a 400-strong choir. “I was delighted to use the W8LM for this event,” said Johnny Palmer, Production Manager, SXS Events. “It was time we invested in a system that allowed for accurate and even coverage. The W8LM is great for shows such as this because of its clarity, simple rigging and aesthetics — and it will be our system of choice when entrusted with highly demanding, high quality production.” The 143-year-old clipper, which had been damaged by fire, is now displayed 11 feet above its dry berth on the Thames and the space underneath is home to an interactive museum where visitors can learn about its history. Go here for more about the W8LM. L-Acoustics KIVA KIVA allows even coverage of large environments where the number of elements constitutes the main factor for system throw and coverage of any audience geometry.
