Midsize Tri-Amplified 3-Way High Directivity Line Array Element

The VT4888 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.


·Advanced technology components: Differential Drive®, neodymium magnet, dual voice coil, Direct Cooled cone transducers for low weight and high output.

·Direct Cooled™ cone transducers for low weight and high output.

·HF Waveguide units couple to create precision vertical slot aperture.

·Radiation Boundary Integrator® (RBI): Patented technology integrates output of individual bandpass elements.

·Advanced construction techniques using PlyMax® 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® system models.
