About this product

VT4887

The VT4887 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 fixed venue installations.
The VT4887 is a compact, lightweight enclosure housing two 8” woofers, four 4” midrange radiators, and two high frequency compression drivers. 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 tubes made of hard-black anodized 6061-T6 Aluminum. Hinge bars made from premium-grade chromoly alloy steel, with epoxy powder coating over zinc-plated surfaces. Cadmium-plated hinge pins and stainless steel quick-release pin lanyards to resist corrosion and weather damage.
VERTEC arrays are rigid for maximum support strength, yet flexible in design and application. The VT4887’s suspension hardware relies on quick-release pins and endmounted metal tubes to couple adjacent VT4887’s together. Enclosure ships with integral front and rear hinge bar set. Protective grille cover/wheel board and soft cover to ensure handy transport for rough road conditions, purchased separately as VT4887-ACC.

Features
  • Advanced technology components: Differential Drive, neodymium magnet, dual voice coil, Direct Cooled cone transducers for low weight and high output.
  • Waveguide units couple to create precision HF vertical slot aperture.
  • Radiation Boundary Integrator (RBI): Patented technology integrates output of individual bandpass elements.
  • Advanced construction techniques and hybrid materials provide exceptionally rigid, lightweight enclosure construction.
  • Rugged DuraFlex exterior finish weatherized components.
  • Patented, integrated S.A.F.E. suspension system: premium heat-treated alloys provide high-strength, reliable hanging arrays.
  • Pre-engineered to accept optional JBL DrivePack amplified electronics package. Rear-panel mechanical attachments and electrical connections ensure upgrade path to self-powered system.
  • For use in stand-alone arrays or in combination with other VERTEC DP SERIES system products.

VT4880

The VT4880 Dual 18" Subwoofer Line Array Element is designed to deliver high quality sound reinforcement of sub-low frequencies for a wide variety of live music and A/V support applications. Typical uses include concert audio and multi-media presentations of all types.
The VT4880 is a rugged, lightweight, centrally-vented enclosure housing two 18" woofers. These advanced components, each fitted with dual voice coils, provide a high output power-to-weight ratio.
The PlyMax enclosure features: foambacked perforated steel grille; speaker cones treated with weather-resistant compounds. Protective end-caps safeguard the suspension hardware while allowing vertical stacking of multiple enclosures on end using integral end-mounted, scuffresistant pads, keyed for aligning surfaces and preventing slippage.
VERTEC suspension systems are engineered for maximum support strength, and flexibility. The VT4880’s suspension hardware (same as the full range VT4889) relies on quick-release pins and endmounted metal frames to couple adjacent units together in rigid arrays. Suspension frames are made from premium-grade chromoly alloy steel with plated surfaces; hinge bars are plated and quick-release pin restraining lanyards are stainless steel to resist corrosion.
The low-frequency capabilities of a multienclosure VT4880 array will be determined by the total number of units coupled. The directivity of a subwoofer line array at any given frequency is proportional to the product of frequency and length of the array. The beamwidth will be inversely proportional to the product of the array’s length and the frequency of interest, typically 20-80 Hz for subwoofer applications.
The more subwoofer elements that are used in the array, the greater directivity will be at lower frequencies, enabling better pattern control. Medium to large arrays can generate extreme amounts of sub-low frequency energy.

Features
  • Advanced Technology Components: Differential Drive® Neodymium Magnet, Dual Voice Coil, Direct Cooled™ cone transducers
  • JBL PlyMax engineered wood materials provide rigid, yet lightweight enclosure
  • Rugged DuraFlex exterior finish; weather-resistant components
  • Patented, integrated S.A.F.E. suspension system with premium heat-treated alloys
