JBL VT 4881A DP Product Details
The VT4881A is a compact, lightweight vented subwoofer enclosure housing JBL’s exclusive new 2269H Ultra Long Excursion 18" woofer. This woofer features neodymium magnet, dual voice coils, JBL’s exclusive Vented Gap Cooling™ and ultra robust composite cone for high excursion and extra long life. Woofer is capable of a peak-to-peak maximum excursion of 89 mm (3.5") while system weight is only 111 pounds.
Enclosure features: foam-back perforated steel grille; speaker cone treated with weatherresistant compound; rigging tubes and hinge bars made from premium-grade alloy aluminum; plated hinge pins; stainless steel quick-release pin restraining lanyards; and inter-locking rubber feet which allow vertical stacking of multiple units, including reverse ground-stacking for cardioid subwoofer array applications if desired. VT4881A rigging hardware (same as in the companion VT4887A compact fullrange system) relies on quickrelease pins and end-mounted metal frames to couple adjacent units together in rigid but flexible arrays.
The VT4881A can be oriented vertically in suspended arrays or it can be ground stacked in horizontal arrays. The low-frequency capabilities of the multi-enclosure VT4881A array will be determined by the total number of units coupled together. The directivity of a 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 Hz - 80 Hz for subwoofer applications. In summary, the more subwoofer elements that are used in the array, the greater directivity will be at lower frequencies, enabling better pattern control.
The VT4881A Compact 18" Arrayable Subwoofer is designed to deliver high quality sound reinforcement of VLF (Very Low Frequency) musical information for a variety of applications including concert audio and theatrical presentations of all types. Ideal companion to VT4887A or VT4887ADP compact three-way systems.
