## About

The entry point to JBL's MkIII redesign of its best-selling nearfield: a 5-inch woofer and 1-inch soft dome in the Image Control Waveguide, bi-amplified at 43 W a side. The port fires forward through JBL's Slipstream slot, so it tolerates a wall or a console bridge right behind it, and four front controls combine into 81 room-EQ presets. Announced November 2026, shipping in North America from January 2027.
