Before we can get into the creative stuff, it’s important to share how Zone Array came to fruition along with the general manufacturing process of the system.
The constructive and destructive concept Zone Array adopts to control and attenuate low frequency was first developed in Sweden in 1989 where a variety of different sized speaker drivers were screwed to plywood sheets. In the mid nineties there were some advancements with 2mm mild steel front plates replacing the ply and itchy ISO wool installed to the rear to try and negate any high frequency emitted out of the rear of the drivers.
When Direct Acoustics was founded in 2007, it was clear the previous concept we had seen needed to be evolved to make the system accessible to all venue types, including marquees and temporary structures.
The biggest limiting factor was the weight. The plywood and mild steel concepts were simply too heavy to be installed into many venues safely so we began to develop the Zone Array into a lightweight advancement using 0.7mm aluminium front plates with a 33% open area (acoustically transparent) perforation pattern. Solid aluminum returns now allowed for a back plate to be pop riveted onto the rear encasing the speaker drivers and melamine foam absorption into a complete panel.
We now had a product that could conform with windshear and weight loading calculations placed upon even the smallest 9m wide clear span marquee frame, Tipis & old barns allowing a variety of unique installs to take place over our decade in the industry.
