The characteristics that qualify a line array as medium format, as opposed to small or large format, is somewhat arbitrary. For this overview, we’ve based the selection on the size of the largest driver in the array, considering those with 8-inch to 10-inch cones to be medium format.
In comparison to enclosures with 12-inch or 15-inch LF drivers, smaller enclosures generally allow wider splay angles within the array elements, which can be helpful for applications where long lines of loudspeakers aren’t feasible because of weight or sightline restrictions.
Further, they’re designed to be flown and taken down quickly, often in “blocks” of individual modules, and to be flexibly adjustable to different splay angles – and many can also be groundstacked. This flexibility can be particularly useful in venues where arrays need to be adjusted regularly to accommodate different types of acts.
Within the medium-format category, there’s a lot of variety. Among the represented brands and models in the listings that follow, the horizontal coverage angle varies from 80 degrees to 150 degrees from a single array column, with most ranging between 100 to 120 degrees. Some manufacturers also offer cabinets with the same “footprint” with differing horizontal coverage, allowing the user to better customize coverage for a particular venue.
Enclosure width varies from a bit over 23 inches to more than 30 inches, and weight for each cabinet ranges from slightly more than 30 pounds to over 100 pounds. Many are self-powered, and others have dedicated external processing and amplification.
Most of these systems use one to two cone drivers to produce the lowest frequencies, and sometimes will roll off the upper frequencies of one LF driver while allowing the other to cover the midrange. HF is covered by a compression driver, or occasionally a ribbon driver, with pattern control via a horn or waveguide with a narrow vertical coverage angle. Thus a 3-way system is effectively created, with the coupling of the two cones effectively creating a larger LF radiating surface. (This is sometimes called a “2.5-way.”)
The following Real World Gear overview of recent models covers a variety of designs based around 8- to 10-inch LF components. It’s not all inclusive but is meant as a solid starting point for further homework. Enjoy the tour.
ENHANCED LISTING
Adamson Systems Engineering CS10
adamsonsystems.com
The CS10 is a two-way, full-range intelligent line array intended for use in a wide variety of applications. Utilizing Adamson’s proprietary network platform, it employs a redundant MILAN scheme with the ability to daisy-chain networked audio between multiple sources, an analog XLR input and output, as well as on-board DSP and amplification. All features of the loudspeaker are controlled and monitored through proprietary CS software.
Acoustically, the CS10 contains dual 10-inch Kevlar Neodymium transducers and a 4-inch compression driver. The critically optimized sound chamber produces a slightly curved wavefront with a nominal dispersion pattern of 110 x 10 degrees (H x V). The chamber’s efficiency allows for increased vertical dispersion without sacrificing high frequency presence in the far field. Patented Controlled Summation Technology further eliminates low-mid lobing normally associated with 2-way line source systems.
The cabinet construction uses marine grade birch plywood as well as aircraft grade steel and aluminum and is equipped with a male and female XLR connector, two etherCON connections and an in-and-through powerCON TRUE1 connection.
TECHNOLOGY FOCUS: The series includes the CS Gateway, a 16 x 16 matrix with 16 channels of DSP containing dual-LAN, Milan-ready AVB, AES/EBU, and analog connections; the NDS network and analog patch bay that sends redundant audio and control on a single network cable; the PDS that insures all systems receive ample power regardless of region; and the CS Bridge to integrate the CS-Series into existing inventories by converting dual-LAN, Milan-ready AVB signal to AES/EBU while also offering six channels of DSP per unit.
OF NOTE: CS-Series loudspeakers offer the same form factors as their S-Series counterparts, and their compatible sonic signatures are designed to be uniform to help ensure scalable configurations. A turnkey Upgrade Kit allows any existing S-Series cabinet to be easily converted to a CS model.
