JBL VT-4880 VerTec Line Array Subwoofer
This dual 18" subwoofer line array element is designed to deliver high quality sound reinforcement of sub-low frequencies for live music and a variety of applications.
Typical uses include concert audio and multi-media presentations of all types.
The VT4880 is a rugged, lightweight centrally-vented enclosure housing two 18" woofers. These advanced components, each fitted with dual voice coils, provide the highest output power-to-weight ratio of any speaker system in its class.
In line arrays, these speakers can be oriented vertically in suspended arrays or groundstacked in horizontal arrays.
The more subwoofer elements that are used in the array, the greater directivity will be at lower frequencies, enabling better pattern control. Because of line array summation, medium to large arrays can generate extreme amounts of sub-low frequency energy.
