Whether hanging from an arena, installed in a house of worship or on a stand for a local coffee-bar gig, P.A. systems are an essential element in any live performance. When looking to upgrade a system, safe and easy rigging, advanced digital control, amplifier integration and great sound are high on the features list—and manufacturers are responding in kind. Here, listed in alphabetical order, is what’s new in line array products for your listening pleasure.

Aiming, speaker curvature and amplification are calculated for each A-Line Acoustics Custom EMMA Curve installation. The company customizes the color, shape and rigging.

The Adamson Metrix W two-way line source array features a 15-degree trapezoidal cabinet design. It has an Adamson ND8-ML 8.5-inch Kevlar neodymium low-mid frequency driver and B&C DE800 1.4-inch HF compression driver with Adamson’s patented HF wave-shaping chamber. A convertible cardioid Sub (a single-sided box that can be arrayed conventionally or in back-to-front pairs) uses the AIR™ System with the Metrix Frame Link Adapter to fly subs behind the array.

Alcons Audio’s LR7 passive two-way line-source system features 90-degree dispersion with seamless coverage due to the ribbon’s all-natural cylindrical (Isophasic) wavefront. Transient response and high peak power handling are 800W/200 ms. It is available in 90- and 120-degree configurations, and can be combined with a pressure-bass or deep-sub system. The LR7Bass double-tuned bandpass bass system features a 12-inch long-excursion woofer with Neodymium magnet structure. The concentric bandpass configuration offers LR7-tuned bass response in full-space (flown) and increased efficiency in half-space (stacked) applications.

The Apogee Sound bi-amped, two-way ALA-3’s modules incorporate two 10-inch cone-type drivers for the LF and dual 1-inch exit compression drivers for the HF. Sharing the same compound trapezoid vented design but larger is the bi-amped, two-way ALA-5, which uses dual 15-inch cone-type drivers for the LF and two 1-inch exit compression drivers for the HF. The tri-amped, three-way ALA-9 uses two 15-inch cone-type drivers for the LF, two 10-inch cone drivers for mids and three 2-inch exit compression drivers for the HF.

The D.A.S. Audio Aero 8A ultracompact enclosure offers a third-generation Class-D power amplifier and digital signal processing. The amplifier offers 250W for the LF loudspeaker and 100W for the HF driver. A two-position HF EQ compensation switch adjusts the HF response for arrays of four, or eight or more units. Low-frequency reproduction is handled by the D.A.S. 8MN 8-inch transducer.

d&b T Series’ T10 cabinet

d&b T Series’ T10 cabinet

d&b audiotechnik T Series includes the T10 cabinet, a passive, two-way design with two 6.5-inch drivers and a 1.4-inch exit HF compression driver. The HF driver is fitted to a waveguide horn, producing vertical line source directivity with a 90-degree horizontal pattern maintained down to approximately 600 Hz. An acoustic lens placed in front of the horn widens horizontal dispersion to 105 degrees; rotation of the horn by 90 degrees relative to this produces an accurate point-source dispersion.

Comprising CROMO 8, 10 and 12 with a power output of 100W, 180W and 300W, respectively, each model from dbTechnologies features asymmetrical CD horns and a mic input on XLR and jack sockets. The Opera 610D compact full-range loudspeaker features a 600W/RMS digital digipro power amp, neodymium components and 24-bit sound processor.
