The monitor has an updated 5-inch woofer with a stronger magnet assembly and an aluminium shorting ring designed to reduce distortion. The updated 1-inch silk-dome tweeter sits in JBL's Image Control Waveguide. The waveguide provides a wide listening area and a stable stereo image. Unlike the previous generation, the Slipstream bass-reflex port is on the front panel. This makes it easier to place the monitor near walls where space is limited.

Two Class D amplifiers drive the woofer and tweeter separately, with a total output of 86 W. According to JBL, the new design provides more headroom and lower self-noise. Four DSP controls offer 81 setting combinations to match the monitor's position, distance from walls and bass/treble balance. The monitor connects through a balanced Neutrik XLR/TRS combo input. The cabinet uses 15 mm MDF and has eight M4 mounting points in a 75 × 75 mm pattern for compatible mounts.
