The VT4881ADP Powered Compact Arrayable 1-18" Subwoofer designed to deliver high quality sound reinforcement of VLF (Very Low Frequency) musical information for a variety of applications including concert audio, corporate A/V and theatrical presentations of all types. Ideal companion to VT4887ADP compact three-way systems.
The VT4881ADP is a lightweight, vented sub-woofer enclosure housing one Ultra-Long Excursion 18" woofer and a JBL DrivePack DP1 fully integrated power and DSP electronics package. The JBL DrivePack, developed in cooperation with Crown and dbx, brings leading-edge technology to the VERTEC DP Series including patented high efficiency Class-I power amplifier technology and onboard digital signal processing. This provides not only unmatched audio quality and performance but also onboard DSP functionality that communicates readiness and operational status to the user, and monitors fault detection of components and electronics.
A new Ultra Long Excursion 18" VLF component, fitted with dual voice coils, and Ultra Robust composite cone provides high output capabilities with an advantageous power-to-weight ratio. Enclosure features: foam-back perforated steel grille; speaker cone treated with weather-resistant compound; rigging tubes and hinge bars made from premium-grade alloy aluminum; plated hinge pins; stainless steel quick-release pin restraining lanyards; and inter-locking rubber feet which allow vertical stacking of multiple inter-locking units, including reverse ground-stacking for cardioid subwoofer array applications if desired. VT4881ADP rigging hardware (same as in the companion VT4887ADP compact fullrange system) relies on quick-release pins and end-mounted metal frames to couple adjacent units together in rigid but flexible arrays.
