The JBL VT4886-SF is a compact, high-performance line array module designed as part of JBL's VTX Series, with the "SF" denoting the "Short Frame" version. This design makes it a versatile tool for applications where a full-size line array box is too large or heavy, but the superior sonic performance and directivity control of a line array are still required. It is engineered to deliver exceptional output and clarity from a small enclosure, making it ideal for front fill, under-balcony delays, side fills, and compact main arrays in theaters, houses of worship, and mobile production. The cabinet incorporates JBL's advanced Differential Drive® dual-voice-coil low-frequency transducers and patented annular diaphragm high-frequency compression drivers for high efficiency, low distortion, and extended bandwidth.

The Short Frame design allows for tighter stacking and more versatile rigging options compared to standard frames. It features integrated rigging hardware that is compatible with the VTX series array frames, allowing it to be flown safely or ground-stacked. Despite its compact size, it offers sophisticated pattern control to ensure even coverage and minimal interference. The VT4886-SF is a solution for sound designers and system engineers who need to deliver big, clean, and controlled sound in spaces with physical or aesthetic constraints, without compromising on the audio quality expected from a top-tier professional loudspeaker system.
