Line arrays keep big crowds at even volume

Curving a stack of cabinets steers sound further without blasting the front rows A line array hangs many identical cabinets close together in a vertical curve. Coupling between them throws sound further, while the curve aims the top boxes at the back of the field and the lower ones at nearby listeners.
