Line Arrays

One of the biggest steps forward in line arrays has been software with configurable DSP and system dispersion prediction, but there have been advances in the physical boxes themselves.

Advances in speaker technology have brought line arrays a long way in just a few years. These systems have never been more adaptable, controllable, and capable of customization in so many parameters. One of the biggest steps forward has been software with configurable DSP and system dispersion prediction. There have also been advances in the physical boxes themselves including steerable sections and some very imaginative rigging systems. Included here are some examples of the new array technology and the customization features that have come with it.

The E12 line source enclosure from Adamson Systems Engineering features the e-Capsule, an aluminum skeletal structure that provides a solid framework for the modular aircraft-grade steel Autolock rigging system. The enclosure houses a 7in. Kevlar neodymium midrange transducer and a 4in. HF compression driver. Aimed by a precision waveguide, they produce a dispersion pattern of 110°x8°. On either side are birch ply enclosures each containing Adamson’s Kevlar neodymium 12in. woofer.

Atlas SoundAL123A-B

For self-powered performance and wide coverage, Atlas Sound designed the AL123A-B large-format line array system with 3600W and network-controlled DSP. Using the integrated EZAL rigging system, one or two people can individually aim up to eight boxes under load while flown or stacked. The boxes are made of birch plywood with threaded attachment fittings and they house a three-way, full-range speaker system with two 12in. woofers, four 6in. MF drivers, and two 1.4in. HF drivers.

Bose RoomMatch RM5540

The Bose RoomMatch RM5540 array module uses six EMB2 extended midband, high-frequency compression drivers with 2in. voice coils and two LF10 ultra-linear 10in. woofers with 3in. voice coils to produce a frequency response of 60Hz to 16kHz (±3dB) and a nominal coverage pattern of 55°x40°. The unit is constructed of Baltic birch plywood on a steel frame and provides two NL4 Neutrik Speakon connectors wired in parallel.


The compact and weather-resistant Entasys line array from Community Professional has a constant vertical beam width from 800Hz up to 16kHz and is available in black, white, and custom colors. Incorporating six 3.5in. neodymium LF drivers, 18 2.35in. midrange drivers and 42 1in. HF drivers, the ENT-FR full-range three-way column has a configurable baffle for straight, curved, or asymmetric curved operation. The ENT-LF low-frequency column has six 3.5in. low-frequency drivers in a straight baffle form.

d&B Audiotechnik V12

d&B Audiotechnik has included two 10in. LF drivers, one horn-loaded 8in. MF driver and two 1 1/4in. exit HF compression drivers in the V12 array loudspeaker. The three-way design exhibits a 120° dispersion pattern down to 250Hz, and the unit can be stacked in arrays of up to 24. It can also be combined with V8s and V-Subs. The enclosure is marine plywood with a PCP (polyurea cabinet protection) finish. The front is protected by a metal grille backed by an acoustically transparent foam layer.

D.A.S. Audio Aero 40A

The Aero 40A advanced line array system (ALAS) from D.A.S. Audio is a three-way, Class- D powered unit using one 12in. woofer, one 8in. midrange, and two D.A.S. M-75N compression drivers attached to a new BPS-2912 waveguide. Monitored and remote controlled over a range of parameters via DASnet, the Aero 40A is constructed of birch plywood and incorporates a two-piece injected aluminum heat sink housing the amplifier and related electronics on the rear of the cabinet.

dBTechnologies DVA T12

The DVA T12 is an active three-way system that is designed by dBTechnologies to serve in long-throw applications and to be scalable for any size setup. It includes a high-end DSP unit and can be set up in sequentially configurable array segments. A neodymium 12in. woofer extends low-end response and midrange uses two 6.5in. neodymium drivers while three 1in. HF drivers with 1.4in. Mylar diaphragms project the highs. With 1500W RMS power, the DVA T12 extends frequency response from 60Hz to 19kHz (±3dB) and provides a maximum SPL of 136dB.


Compact enough for either touring or permanent installation when coupled with its companion subwoofer, the JFL118, the EAW JFL213 two-way line array module is equipped with two 10in. cone transducers and three horn-loaded, 0.75in. exit/1.75in. voice coil compression drivers. Switchable between single or bi-amp powering modes, the JFL213 also has a rigging system that allows it to be mounted in an array of up to five modules or pole-mounted with two units.

Electro-Voice X-1

Premiering at InfoComm 2014, the new X-Line of line array speakers from Electro-Voice features a new integrated rigging system, FIR-Drive optimization, and improved Hydra wave-shaping devices. The X-1 is a 12in. compact module for small-and midsize venues with its SMX 12in. woofer coupled to an EV-exclusive Mid-Band Hydra device. There are two new ND2R ring-exit, high-output 2in. titanium compression drivers coupled to a pair of WCH constant energy planar wave generators on a 90° waveguide for HF linear response.

Designed by JBL to put more power into a lighter and more compact line array system, the VTX series offers eight models to suit a range of sound environments. One of the line’s primary features is the D2 Dual Driver, which uses two voice coils and merges two compression drivers into one transducer with a single acoustical output. The V25 full-size, three-way, high-directivity line array has two 2000W Differential Drive woofers, four midrange transducers, and three of the new D2 Dual-Diaphragm Dual-Voice- Coil compression drivers.

The KP102 line array element, variable beam speaker from K-array is a passive system comprised of 12 3.15in. neodymium magnet cone drivers mounted in a stainless steel enclosure. This model can be used to fit a variety of difficult coverage situations using its linking and hanging options. Each one can be set for 8Ω or 16Ω to vary the number of elements to be run on a single amp channel. Available in black, white, or custom colors, the KP102 can reproduce the entire vocal range from 100Hz. The unit is IP54 rated for outdoor use, as well.

Nexo STM

Nexo’s STM (Scale Through Modularity) array system can be arranged like Legos in any combination of modules to suit the venue and the type of show. Through their PistonRig and REDlock rigging, the units can be set up in a simple ground stack, double column, or triple column in any combination of main, bass, sub, and omni modules. Up to 12 of them in groups of three can be powered by the versatile Nexo Universal Amp Rack.

Outline GTO C-12

One of the stars of the Outline array family, the small but powerful full-range line source GTO C-12 packs two 12in. LF drive units, four 6.5in. MF drivers, and two 3in. diaphragm HF drivers to provide a frequency range from 65Hz to 17kHz (±3dB) and a horizontal dispersion of 90°. The Outline V-Power concept is based on the V-shaped front baffle, which allows individual array-coupled line sources to be placed very close together for smooth HF response.
