The JBL VT4889 is a professional passive three-way line array speaker. The VT4889’s innovative design incorporates modular components that can be either flown as a line array, or it can be ground-stacked or pole-mounted for front of house applications. Incorporating the latest in transducer technology from JBL’s professional reference systems, the JBL VT4889 produces optimum frequency response from its two side-firing 15-inch woofers, and near theoretical maximum efficiency from its large 1.4-inch compression driver.
JBL’s VT4889 three-way line array element features two 15′ woofers, four 8′ mid-frequency drivers, and three 3’-diaphragm high-frequency compression drivers. These precise and reliable speakers have a frequency range at -10 dB of 40 Hz to 18 kHz.
The appropriate accessories for this line array system include the VT4889-AF and VT4889-SF suspension frames, the VT4889-RIG hinge bars, and the VT4889-DOLLY for transportation.
The VT/VerTec line-array series has been on stages alongside names like Aerosmith, Rush, Alicia Keys, Sheryl Crow, Miley Cyrus, and many more. Its reliability, power, and compact mid-sized form make it excellent for touring shows, short-term events, and fixed installations.
From the Manufacturer
The VT4889 Three-Way Line Array Element is designed to deliver high-quality reinforcement of music and speech in a variety of applications including concert audio and corporate A/V presentations of all types for both portable users and fi xed venue installations. The VT4889 combines time-tested acoustical physics with JBL’s innovative transducer research and design in a premium-grade system package.
JBL’s VERTEC (Vertical Technology) builds on proven line array theory as demonstrated in JBL’s line array systems in the early 1970’s. The VT4889 is a rugged, lightweight enclosure housing two 15″ woofers, four 8″ midrange radiators, and three high- frequency compression drivers. These advanced components provide the highest power-toweight ratio of any speaker system in its class.
Enclosure features foam-backed lowfrequency grilles, dense protective foam inserts for midrange apertures, and a fine steel mesh grille to protect high-frequency apertures. All speaker cones are treated with weatherresistant compounds. Rigging frames and hinge bars are made from premium-grade chromemoly alloy steel, with epoxy power coating over zinc-plated surfaces; hinge pins are plated and quick-release pin restraining lanyards are stainless steel to resist corrosion and weather damage.
VERTEC arrays are rigid for maximum support strength, yet flexible in design and application. The VT4889’s suspension hardware relies on quick-release pins and end-mounted metal frames to couple adjacent VT4889’s together. Enclosure ships with available front and rear hinge bar set (VT4889-RIG), available padded soft bag (VT4889-COVER) and protective grille cover/wheelboard (VT4889-DOLLY) to ensure handy transport for rough road conditions.
