JBL VT-4888 VerTec Midsize Tri-Amplified Three-Way High-Directivity Line Array Speaker
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, lightweight enclosure houses two 12" woofers, four 5.5" midrange radiators, and two high frequency compression drivers. Advanced components provide a high power-to-weight ratio.
VERTEC arrays are rigid for maximum support strength, yet flexible in design and application. The VT4888’s suspension hardware relies on quick-release pins and end-mounted metal tubes to couple adjacent speakers together.
