Tech Showcase: Line Arrays

Here are some of the latest speaker arrays on the market.

This month we take a look at a variety of line array speaker systems. Line arrays are typically made up of identical loudspeaker elements and mounted in a vertical line to create a directable and focused source of sound. This configuration and the spacing between adjacent drivers yield constructive interference, send sound waves further than traditional horn-loaded loudspeakers with more evenly distributed audio coverage. Match physical drivers with electronics and line arrays will become “steerable,” which comes in very handy in many real-world applications.

The S10 from Adamson Systems Engineering is a two-way, full-range line source cabinet containing two ND10-LM Neodymium Kevlar drivers (2x 16Ω) and an NH4TA2 1.5in.exit compression driver (8Ω) with an optimized sound chamber that produces a slightly curved wavefront with a nominal dispersion pattern of 110° horizontal x 10° vertical. According to Adamson, the chamber’s efficiency allows for increased vertical dispersion without sacrificing high frequency presence in the far field. The full range capability of the S10 (from 60Hz) makes it well-suited for applications without a subwoofer. Patent-pending Controlled Summation Technology further eliminates low-mid lob-ing normally associated with two-way line source systems. Increased vertical coverage enables the S10 to cover theater, arena, and stadium environments with reasonable loudspeaker quantities as well as dance clubs, medium-sized festivals, corporate events, and contemporary houses-of-worship.
