The field has become quite competitive in the area of line-array loudspeakers. In an effort to gain the edge, companies have introduced a new level of soundscaping through hardware rigging, multi-amplifier control, and software sound-tailoring applications. Smaller enclosures packing more punch are showing up everywhere, and the specs on these systems have reached a new plateau for efficiency and power handling.

From Adamson Systems Engineering, the Metrix is a light, ultra-compact two-way true line-array system. Designed for medium SPL for small to mid-size venues or as an under-hanging side and front or balcony fill in arrays of six or more elements, the Metrix offers two rigging system options. It also incorporates a newly designed Adamson ND8-ML 8.5in. Kevlar neodymium low-mid frequency driver and the B&C DE800 1.4in. high-frequency compression driver with a patented high-frequency wave-shaping chamber. Each enclosure has a 5-degree vertical and 120-degree horizontal coverage pattern.

Alcons Audio offers the LR14, a passive, two-way line-source loudspeaker system as a vertical array either stacked or flown for both touring and permanent installation. The unit features an RBN401 pro-ribbon HF driver, and it is SignalIntegritySensing (SIS) pre-wired for very high damping and reduced distortion. The horizontal dispersion is 120 degrees and the vertical dispersion is 15 degrees with a maximum RMS power-handling capability of 400W and maximum peak power spec of 1000W. For extended bass response, the LR14 can be combined with the pressure-bass LR14B, the deep sub-system BF181, or both.

The 2"×10" AL10 line-array system from A-Line Acoustics features Line Source Replication for maximum projection and detail, and it uses dual 4-pin or optional 8-pin Speakon connectors for a high-power solution in a small package. The frequency response spec is 75Hz to 18kHz with an 800Hz crossover through 10in. neodymium woofers. The AL10A is available as a powered version and hybrid-active line-array version using the AL10X unpowered slave enclosure. The unit uses XLR connectors — those used by all ICE modules in the A-Line Acoustics product line.

The ALA-9 — the largest of the ALA line-array series from Apogee Sound — is a triamped three-way, electronically coupled system with 1200W LF, 600W MF, and 450W HF response. The unit exhibits a vertical dispersion of 10 degrees and a horizontal dispersion of 90 degrees. The nominal impedance on the low-frequency section is 8Ω and 4Ω on the mid- and high-frequency sections. The ALA-9 provides a maximum SPL of 136dB continuous and 142dB peak. In either a flat-pack or tight-pack configuration, the enclosures are joined together with connecting bars for the desired angular relationship and secured in place by aircraft-grade retention pins.

For delivering speech intelligibility in a live acoustic environment, Bose offers the Panaray MA12, deployed either singly or in stacked arrays for tight high- and mid-band pattern control. The MA12 reproduces the entire critical vocal range from 155Hz to 112kHz with no crossover required. Depending on the specific type of configuration, the MA12 can be matched in optimum frequency response with the Panaray System Digital Controller for active equalization. The unit has 12 2 1/4in. drivers per enclosure, 300W continuous power handling, and 160-degree horizontal coverage with a maximum acoustic output of 130dB SPL at 3.28ft.

The Q-Series array loudspeakers from d&b audiotechnik are a group of four models using conventional rotatable CD horns, dipolar driver arrangements, and low-compression vented designs with high-excursion drivers and toroidal wave-shaping devices. The Q7 is a passive crossover, two-way enclosure with a 1.3in. exit HF driver and two 10in. LF drivers exhibiting a 75-degree horizontal spread. The 40-degree vertical dispersion angle is maintained down to 400Hz. For extra versatility in mounting applications, the horn can be rotated 90 degrees without removing the metal grille. The various components available from d&b audiotechnik present a wide array of combinations and mounting options.

The Aero-38 externally powered medium-format line-array module from D.A.S. Audio incorporates wide-frequency response in a compact enclosure by integrating low-, mid-, and high-frequency transducers in a single unit. Two 12in. loudspeakers use 4in. voice coils to handle the low end. Two 10in. cones with 3in. voice coils provide the midrange and one ND-10 large-format compression driver pushes the highs. This uses a 4in. titanium diaphragm, copper-clad aluminum EFW voice coil, and a 1.5in. exit throat coupled to a Serpis high-frequency plane-wave generator. This combination allows a frequency range at -10dB points of 50Hz to 18kHz. The horizontal dispersion figure is 90 degrees.

For touring and theatrical applications, Duran Audio offers the Axys Target system with Digital Directivity Synthesis (DDS). At the heart of the system is the Axys Target U-16 line-array module with a vertical slot-diffraction HF horn coupled to a 1in. neodymium compression driver. The self-amplified unit also has two 6.5in. direct radiating low-mid drivers. An internal class AB amplifier provides 530W RMS into 4Ω for the low-mid and 200W RMS into 8Ω for HF performance. The Axys Target U-16 has a total frequency response of 160Hz to 20kHz ±3dB and a 90-degree horizontal dispersion pattern.
