JBL 4891 Full Range Loudspeaker
JBL’s commitment of providing audio professionals the best tools for their work continues with the Array Series Stage Monitors. These systems provide ultimate performance for critical monitoring situations that require high quality sound at high SPL. Both models are very compact to allow unobtrusive presence on stage while providing smooth, predictable coverage and response from a single box or multiple boxes. Their linear amplitude and phase response increases the headroom before feedback. Integration of advanced design high power transducers, a new generation of horns, and advanced control electronics provides clearly superior performance. Reliability is designed in without having to rely on intrusive signal processing.
