JBL VT4889 Fullsize Tri-Amplified Three-Way High Directivity Line Array Element, 45Hz - 16kHz Frequency Response

The JBL 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-to-weight ratio of any speaker system in its class. Enclosure features foam-backed low frequency grilles, dense protective foam inserts for midrange apertures and a fine steel mesh grille to protect high-frequency apertures.

Speaker cones are treated with weather resistant compounds. Rigging frames and hinge bars are made from premium-grade chromoly 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 VT4889s together.
