The JBL VT4881A is a professional arrayable subwoofer for very-low frequencies (VLF). VLF applications include music recording and sound reinforcement. With an 8″ (200 mm) low frequency driver, active 3-way system and selectable settings like the KickBack and the RoomFeel function, you obtain a powerful and adjustable sub bass system. You can even make adjustments remotely using the optional IR wireless remote.

Each subwoofer has a self-cooling aluminum voice coil, flux-efficient VAST magnet system, which provide highly dynamic bass performance with minimal weight, and linear Xmax control.

Normally two or more VT4881As are used together, with their bass coverage being adjusted using JBL’s ArrayCalc software.
