JBL 70J-1

JBL 70J-1

Another manufacturer providing both column and line source elements is JBL. The CBT series features the 70J-1 model that uses a 70cm "J"-shaped column array with patent-pending Constant Beamwidth technology. The driver complement is 16 1in. tweeters and four 5in. woofers that provide a frequency response of 60Hz to 20kHz. The system provides an asymmetrical vertical coverage pattern that is switchable between 25 degrees or 45 degrees; horizontal coverage is 150 degrees. Maximum SPL is 127dB peak.

One of the more recent players is K-Array. The KK100 features 16 2in. neodymium transducers mounted in a 41.02in. tall stainless steel chassis. The impedance is selectable between 8Ω or 32Ω, and the operating frequency range is 150 Hz to 20 kHz. The coverage is 100 degrees horizontal and 7 degrees vertical with a peak SPL of 125dB. The system weight is 8.38 lbs. Additional products such as the KKS50 or the KL12 sub can be used to extend the operating frequency range.

L-Acoustics KARAi

L-Acoustics KARAi

From L-Acoustics comes the KARAi modular line source element, which is a two-way biamplified system comprised of two 8in. neodymium low-frequency drivers and a 3in. neodymium diaphragm high-frequency driver coupled to a DOSC waveguide. Horizontal coverage is 100 degrees and maximum SPL is 139dB. The frequency response is 55Hz to 20kHz. Addition of the SB18i low-frequency extension lowers the response to 32Hz.

Mackie HDA

Mackie HDA

New from Mackie is the HDA arrayable powered loudspeaker, which incorporates Class D Fast Recovery amplification with a switch-mode power supply. Amplifier power is 500W RMS for the lows and 100W RMS for the highs. An EAW-designed 12in. low-frequency transducer and two 1.7in. compression drivers provide a frequency response of 57Hz to 20kHz and a maximum calculated peak SPL of 134dB. Horizontal coverage is 110 degrees and the vertical coverage is 20 degrees.

Martin Audio OmniLine

Martin Audio OmniLine

Coming in at just 7.9lbs. for one module, Martin Audio's OmniLine micro line array is perhaps the smallest of the modular systems. The frequency response of one two-way element is 85Hz to 20kHz from complement of two 3.5in. low-frequency drivers and five 0.55in. soft dome tweeters. Coverage is 100 degrees horizontal and 5 degrees vertical and maximum SPL is 110dB peak from a single element. The system is scalable from four to 32 modules.

Meyer Sound Mina

Meyer Sound Mina

Meyer Sound's product line up also includes column array loudspeakers and line array elements. The self-powered Mina compact curvilinear array loudspeaker is the smallest within the Milo family at a little more than 20in. wide with rigging. The frequency response is 66Hz to 18kHz and the maximum peak SPL is 128dB. The system uses two 6.5in. low-frequency transducers, one 3in. diaphragm, and 1.2in. exit compression high-frequency driver, which is coupled to a proprietary Ribbon Emulation Manifold (REM) and a 100-degree horizontal constant directivity horn.

Nexo S805

Nexo S805

The Geo line from Nexo includes the S805 array module, which is loaded with an 8in. long-excursion neodymium woofer and one 1in. throat neodymium driver mounted on a Hyperboloid Reflective Wavesource. Coverage in the non-coupling plane is configurable to 120 degrees or 80 degrees. The frequency response is 67Hz to 19kHz. The weight is 28.6lbs. The Geo S805 can be used in arrays in conjunction with the Geo S830 and CD 12 Sub-Bass cabinets.

Outline Mini-COMPASS iMode

Outline Mini-COMPASS iMode

Packing a lot of technology in a relatively small package, Outline's self-powered Mini-COM.P.A.S.S. iMode boasts onboard DSP and a built-in web server for system control via standard web browser. Also featured is variable asymmetrical horizontal directivity, which allows coverage to be set in steps of 15 degrees from 60 degrees to 150 degrees. Frequency response is 100Hz to 20kHz from a driver complement of four 5in. vented-loaded woofers and two 1.75in. compression drivers. Peak SPL is 131dB.

Peavey SSE LA

Peavey SSE LA

Peavey Electronics offers line source modules and a column system through its Architectural and Sanctuary series divisions, respectively. The SSE LA column comprises 16 2in. drivers on a compound-radius curved line array, which provides dual coverage 20 degrees vertical for long throw and 40 degrees vertical for the near field. Horizontal coverage is 130 degrees. Frequency response is 174Hz to 18kHz and maximum SPL 122dB peak.

QSC KLA 12

QSC KLA 12

QSC's KLA 12 is a self-powered two-way system with a 12in. cone transducer and a 1.75in. compression high-frequency driver mounted in an ABS enclosure. Ar-Q (Arquate Equalization) processing allows for array tuning for the number of cabinets used in the array. Coverage is 90 degrees horizontal by 18 degrees vertical and maximum SPL is 131dB. The amplifier design allows for up to five KLA 12s (or any combination of KLA 12s and its companion subwoofer, KLA 181) to be powered off a 15-amp/120V electrical circuit.

Renkus-Heinz Iconyx IC Live

Renkus-Heinz Iconyx IC Live

Another manufacturer with line source elements and column designs is Renkus-Heinz. The Iconyx IC Live digitally steerable line array allows the user to define the opening angles for up to four beams per array module. Eight Class-D amplifier channels with integral DSP drive five 6.5in. low-frequency transducers and three 1in. compression drivers. The frequency range is 80Hz to 20kHz and peak SPL is105dB at 100ft. Horizontal coverage is 150 degrees to 3kHz and 120 degrees above 3kHz. Vertical opening angles for a single module are 20, 25, and 30 degrees with an adjustable aiming angle of ± 30 degrees.

WorxAudio TrueLine V5T

WorxAudio TrueLine V5T

The TrueLine V5T from WorxAudio incorporates dual 5in. cone drivers and a 1in. exit compression driver coupled to a FlatWave Former wave-shaping device. The horizontal coverage pattern is 120 degrees and the vertical coverage is 10 degrees. Exterior color options available are black or white.
