A single active monitor with a 4-inch high-excursion woofer and 1-inch silk-dome tweeter, the AIAIAI Unit-4 Gen 2 Wireless+ delivers reference-grade monitoring in a 2.5kg portable enclosure. Bass extension reaches down to 40Hz, providing controlled low-end response alongside detailed highs and articulate mids. The rechargeable battery runs for over 20 hours on a single charge, making this monitor genuinely portable for location recording, field production or simply moving between rooms. An ergonomic carry handle on the rear panel makes transport straightforward. Connectivity includes Bluetooth 5.2 for wireless streaming and analogue audio inputs for wired sources. The Unit-4 Gen 2 integrates with AIAIAI's W+ Link wireless system, enabling ultra-low-latency transmission when paired with compatible transmitters. The flat frequency response ensures accurate audio reproduction across mixing, production and content creation applications. Construction uses modular, repairable components built from recycled plastics, allowing future servicing and parts replacement to extend the monitor's working life.
