JBL Line Array – Matrix
Line Array. There’s one for everybody
Line arrays are nothing mystical. The theory and the math of aligning arrays of multiple drivers have been around for more than half a century. Back
in the ‘70’s JBL was already utilising line array technology in the 4682 loudspeaker enclosure. It was not until the ‘90’s that line array technology
as we know it today was seriously experimented with.
The basic theory of line array is the coupling of multiple drivers, albeit that they are in separate enclosures, to better control vertical dispersion
patterns and to increase the SPL at greater distances.
JBL VerTec, (
Vertical Technology), was one of the pioneers in vertical line array. Today VerTec is the number one choice of line array by more
live production companies worldwide than any other line array. In addition, it is also the most permanently installed line array, offering more
performance and accuracy for your money than any other line array available.
It is from the VerTec DNA that the VRX900 Series Constant Curvature Line Array was born. The VRX900 is a cost effective, compact, lightweight
and highly efficient series of cabinets, providing line array solutions for smaller applications. Designed for situations where longer throw and high
performance is required, and the aesthetics of small single, vertical drops as opposed to large multi-tier horizontal arrays, are desired.
On the enclosed catalogue CD you will find a number of white papers on line array theory to help you better understand why line arrays are the way
of the future. Also you will find the VerTec and VRX line array calculators which are designed to assist in system design for almost any application.
Please do not hesitate to contact our Technical Resource Group for any guidance or design assistance you may require.
Below is our “Meet the Family” comparison chart. This chart shows the entire JBL family of line array element specifications, allowing for easy
comparison and a quick reference to each elements component compliment and performance.
