The VT4881A Compact Arrayable 1-18" Subwoofer 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.
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 weather resistant 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.
