The VT4886 Subcompact Passive Three-Way Line Array Element is designed to deliver high-quality 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-to-weight ratio with more SPL output than other systems in its class.
A proprietary waveguide seamlessly integrates MF and HF section output in a next-generation 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 ground-stacked 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.
