The VT4886 Subcompact Passive Three-Way
Line Array Element is designed to deliver highquality reinforcement of music and speech in a wide variety of applications including concert
audio and corporate A/V presentations of all types for both portable users and fixed venue installations.
The VT4886 is a very compact, lightweight enclosure housing two 6.5" low
frequency transducers, four 2.5"
midrange components and two 1" high
frequency compression drivers. Advanced component design and density provide an extremely high power-toweight ratio with more
SPL output than other systems in its class.
A proprietary waveguide seamlessly integrates MF and HF section output in a nextgeneration implementation of JBL's patented R.B.I. (Radiation Boundary Integrator) technology, providing precise wavefront control and optimum inter-enclosure coupling. JBL Thermomaster technology improves heat transfer while reducing mid section power
compression. LF transducers feature patented Differential Drive technology and are matched to a low-
frequency diffraction absorber with a tuned resonant-chamber that reduces cavity
resonance and cabinet edge
diffraction effects. A highly refined passive network minimizes insertion loss while ensuring precise
impedance matching between LF, MF and HF sections.
Application flexibility was a key design criterion. Possible uses include: suspended or ground-stacked (standalone or with the companion
VT4883 subcompact
subwoofer) for
FOH, offstage fill,
stereo in-fill, center cluster or
delay cluster use; suspended with
VT4883 enclosures and additional groundstacked VERTEC subwoofers for 4-way
FOH use; underbalcony (1-4 enclosures); distributed front fill (1-2 enclosures); modular, constant curvature horizontal
line array; downfill use with mid- or full-sized VERTEC models; pole mounting (tripod-mounted or with optional extension rod for the
VT4883). For optimum performance,
DSP presets have been specifically engineered for the abovementioned configurations.
