Hanging out above a wide stage, a big line array can be as impressive in sight as well as sound. Physically-adjustable throw and dispersion offer the versatility needed for venues with adjustable seating or challenging acoustics. With appropriate installation tuning and the right front of house DSP, a line array can deliver amazing sound quality. Here are some of the current features and innovations from the engineers and designers of these critical products.
1. Adamson E15
This array has been receiving recognition in the touring market this year, traveling on some high profile tours and picking up industry awards. The E15 is a three-way, true line source enclosure incorporating proprietary transducer and waveguide technology to reduce the cabinet’s weight and overall footprint. The core is the aluminum E-Capsule; its patent-pending skeletal structure provides an accurate and rigid frame for mounting the modular aircraft-grade steel Autolock rigging system, while simultaneously housing a series of efficient mid-high components coaxially mounted on Adamson’s Co-Linear Drive Modules.
2. Alcons LR18/120
Last month, Alcons announced the launch of this three-way format line-source sound system, combining a 120-degree wide dispersion sound quality with SPL capabilities and throw. The LR18/120 features power handling of 1500W with an RMS-to-peak power handling ratio of 1:15. A horn-loaded 6.5-in midrange transducer is included, coaxially mounted behind the HF driver with the LF section consisting of two reflex-loaded 8-in woofers with 3-in voice-coil Neodymium motor structure. System drive is provided by two channels (bi-amp) of the Sentinel amplified loudspeaker controller, featuring LR18 specific drive processing and feedback for each array configuration, with new presets including “VHIR processing” to allow for phase-matching with any Alcons system. Signal integrity sensing prewiring is included, allowing for cable/connector compensation between the LR18/120 and ALC. The rigging system also allows users to enable angle-setting on the cabinets without lifting the array, with a working load limit of 24 cabinets under 10:1 safety.
3. Bose ShowMatch DeltaQ SM20
These full-range array modules allow precise alignment for custom tailored sound coverage with its 20-degree nominal vertical angle and its field changeable waveguides for 70 or 100-degree horizontal dispersion (optional 120-degree). For odd shaped rooms or unusual seating layouts, one waveguide can be changed for asymmetrical horizontal coverage patterns. These 2-way modules provide a frequency range from 59Hz to 18kHz using an external 2-channel amplifier. Each unit is composed of four Bose EMB2S compression drivers and two 8in. neodymium high-power woofers to produce output as high as 145 dB SPL. Up to 24 modules can be stacked using 3-point “quick pin” rigging. Long term LF power handling is 400W while HF power handling is rated at 100W (1800W peak).
4. Clair Brothers C-Series
At InfoComm, Clair Brothers introduced a custom configured variable waveguide 10-inch option to it’s C-Series, the C10-TrueFit (the TrueFit option was already available in the 8-inch and 12-inch line arrays in the C-series as well as in the 12-inch curved arrays). TrueFit waveguides are custom-configured, continuously variable waveguides and designed to order. The idea is to reduce energy wasted on walls, and to extend the stereo image over a greater audience area. A TrueFit array is designed collaboratively with the customer, utilizing proprietary progressive azimuth design software that yields a fluid-form waveguide with continuously variable geometry. Finished waveguides are CNC-milled in-house. Clair’s C-series speakers introduced new transducer and digital beam-steering technology. Clair Bros. describes the C10 as the only 15° vertical, dual 10” format line array available with Clair TrueFit technology. The C10 is available with a variety of horizontal waveguide patterns. Standard waveguide is 110°H x 15°V, with horizontal waveguides 70°-to-120° (10° increments) also available. The C10, like the C12 and C8 (the 12-inch and 8-inch speakers in the C Series), features new transducer technology offering significant weight reduction and reduced amplifier channel requirements.
5. d&b audiotechnik KSL
A new addition to d&b’s family of line array products is the KSL System; its got the same broadband directivity, low frequency extension and advanced rigging options of the larger GSL line. The KSL8 provides 80-degree horizontal dispersion while the KSL12 has 120-degree coverage. They use twin, front aligned 10in. drivers along with two side firing 8in. drivers to allow carefully controlled directivity from the whole unit. For the mid-range it has an 8in. horn with an 8in. driver and the HF section is a pair of 3in. voice coil drivers mounted in a wave shaping device. The subs in this line, the SL-SUB (flown) and SLGSUB (ground), are equipped with two forward facing 21in. drivers and a single, rear facing 21in. driver that extend the LF response down to 30Hz.
6. DAS Audio AERO-20.120A
This two-way powered line array from DAS Audio features the AX rigging system and low-profile fly-bar that reduces the space needed between the upper rigging point and the top of the array. For low and mid-range coverage there is a 12in. 12AN4 DAS speaker incorporating a light aluminum voice coil bonded to a new fiberglass reinforced cone. On the HF side, there is the M-75N compression driver, titanium diaphragm and 3in. voice coil. This is attached to an aluminum waveguide with 120-degree horizontal coverage. The whole enclosure is constructed using birch plywood and finished with the ISO-flex coating. The low frequency amplifier outputs 800W continuous power while the HF amp has 400W. The unit uses top of the line AD/ DA converters and remote monitoring and control is provided by way of DASnet.
7. EAW KF810P
This compact installation line array from EAW incorporates many key features desirable for installation units including black or white finish, hidden wiring, concealed 3-point rigging and a weather option. The module is composed of twin HF compression drivers with 3in. voice coils along with four 5in. MF drivers and two 3in. voice coil 10in. LF drivers. The integrated horn brings all these elements together using Concentric Summation Array (CSA) technology to output up to 145dB SPL. With CSA, multiple subsystems sum coherently, without interruption to either HF or MF wavefronts. There is an option for 80 or 120-degree horizontal dispersion. The unit is equipped with bi-amp LF, MF/HF amplification and tuned spacing of LF components for extended LF pattern control. Dynamic Optimization actively tracks input spectrum and power delivery, continually maximizing output and fidelity at any drive level.
8. JBL VLA901i
This three-way full range loudspeaker for line array installation has two JBL 2265H, 15in. diameter, dual 3in diameter voice coil, neodymium LF drivers.
