Large-format line arrays deliver in terms of output, and in many cases, are now much more than simply loudspeakers, better described as integrated systems. The vast majority of the models we’re presenting here incorporate dedicated power and DSP packages (onboard or rack mounted), and are outfitted with sophisticated control, networking, and optimization capabilities. Integral rigging is user-friendly and marked by precision and ease of use.

It’s still surprising to some that line arrays have been around for more than half a century in the guise of column loudspeakers, and most of them in earlier days were voice-range only. Their application was generally for highly reverberant spaces, where a narrow vertical dispersion avoided exciting the reflective room boundaries and, as a result, improved intelligibility of the spoken word.

V-DOSC from L-Acoustics was the first (in the mid-1990s) to show the concert sound world that more level and smoother frequency response can come from fewer drivers in a line array. Now, large-format line arrays (which we loosely identify as models with 12-inch and larger woofers) exist in a wide range of types and options.

Driver configuration and enclosure design remain defining factors. Some models employ dual woofers with a center high-frequency section to provide horizontal symmetry. The simplest systems may just have a single cone and high-frequency driver. Quasi 3-way solutions use dual woofers, but low-pass one woofer at a lower frequency than the other, thereby eliminating lobing at higher frequencies where the drivers become displaced with relation to the frequencies being reproduced.

True 3-way designs operate separate low-, mid- and high-frequency drivers, each in their own band. There are several approaches to horn loading, which can provide higher sensitivity for additional power. And now, we’re seeing some 4-way systems, with the mid-frequencies subdivided into two sections.

In the listings that follow, note that the horizontal dispersion spec is provided for all models. Vertical dispersion varies, dependent on array structure and configuration.

Keep in mind that several companies present more than one choice in this category. Several of them also offer complementary array elements with wider angles of coverage that perform better as the lowest near-throw enclosure(s) in vertical arrays. Enjoy this look at the latest large-format line arrays.

Adamson Systems Engineering E15
adamsonsystems.com

The Adamson E15 is a 3-way true line source enclosure incorporating proprietary transducer and waveguide technology that reduces weight and minimizes the footprint. The heart of the E15 is the E-Capsule, precisely engineered and constructed of lightweight aluminum. The 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 pioneering Co-Linear Drive Modules.

Two vector corrected low-excursion 7-inch Neodymium midrange transducers paired with two next generation 4-inch HF compression drivers energize the drive modules and provide seamless mid-high energy with minimized distortion at very high SPL levels. Critically optimized waveguides based on a prolate-spheroidal geometry ensure precise pattern control and minimum THD, producing a nominal (-6 dB) dispersion pattern of 90 x 6 degrees (H x V).

The E-Capsule is flanked with two separate, vented birch ply enclosures, each containing proprietary Neodymium 15-inch woofer, capitalizing on the advantages of Adamson’s Advanced Cone Architecture and optimized heat dissipation management of the 4-inch voice coil.
