JBL VT4887A VerTec Compact Bi-Amplified Three-Way High Directivity Line Array Element
This speaker 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.
Its rugged, compact and lightweight enclosure houses two 8" woofers, four 4" midrange radiators, and two high frequency compression drivers.
VerTec’s advanced components provide an extremely high power-to-weight ratio. Enclosure features include foam-backed low frequency grilles, dense protective foam inserts for midrange apertures and fine steel mesh grille to protect high-frequency apertures. Speaker cones are treated with weather-resistant compounds.
