The VT4883 Subcompact Dual 12" CardioidArrayable Subwoofer Line Array Element is a companion low frequency extension for the VT4886 subcompact 3-way enclosure. Designed to deliver high quality sound reinforcement of sub-low frequencies for a wide variety of live music and A/V support applications, typical uses include concert audio and multi-media presentations of all types.
The low-frequency capabilities of a multienclosure VT4883 array will be determined by the total number of units coupled. The directivity of a subwoofer line array at any given frequency is proportional to the product of frequency and length of the array. The beamwidth will be inversely proportional to the product of the array's length and the frequency of interest, typically 20-80 Hz for subwoofer applications.
The more subwoofer elements that are used in the array, the greater directivity will be at lower frequencies, enabling better pattern control. Medium to large arrays can generate extreme amounts of sub-low frequency energy.
