Purposeful design
Every detail in the SRX800 Series was purposefully designed and thought through with full consideration for its intended use. Ergonomically designed handles support an easy, non-fatiguing grip for streamlined handling. M10 suspension points, indexed feet, and pole/tripod mounts support a wide, flexible array of configurations.

Transducer technology

JBL’s 2432H is the only neodymium 3" voice coil compression driver in this class, delivering very high power levels and smooth, crystal clear sound.
