WiiM Sub Pro - Smart Active Subwoofer

The WiiM Sub Pro is a powerful active subwoofer designed to deliver deep, precise low-frequency performance that enhances music, movies, and games. Built around a custom 8″ long-throw driver and a high-power Class-D amplifier, the Sub Pro extends bass response down to 25 Hz while maintaining clean, distortion-free output — bringing impactful low end that fills the room and blends naturally with your main speakers.

Featuring next-generation connectivity, the Sub Pro supports Wi-Fi 6E, Bluetooth 5.3 (LE Audio) and Ethernet, making it easy to connect wirelessly with compatible WiiM products or integrate via RCA into legacy systems. The built-in AI-powered RoomFit™ auto-calibration intelligently analyzes your room’s acoustics and placement to optimize bass performance, eliminating guesswork and ensuring rich, balanced low frequencies.

Control and tuning are managed via the intuitive WiiM Home App, where you can adjust crossover frequency, level, phase, latency and apply a 10-band parametric EQ for precise bass tailoring. Whether used as part of a WiiM ecosystem or added to a standalone audio setup, the Sub Pro adds a new dimension of depth to your sound, delivering bass you feel as much as you hear.
