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 inter-locking 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 quick-release pins and endmounted
metal frames to couple adjacent units
together in rigid but flexible arrays.
