WiiM Sub Pro

Smart Bass. Perfectly Tuned.

Deep, Low Distortion Bass to 25 Hz
8" high-excursion woofer and 250 W Class-D amp deliver room-shaking lows for movies, music & gaming without boom or breakup.

AI RoomFit Auto-Calibration
One-tap tuning analyses your space and tailors bass response automatically—no mic kits or guesswork required.

True Wireless Flexibility
Next-gen Wi-Fi 6 and Bluetooth 5.3 let you place the sub anywhere near power; RCA input adds instant compatibility with any receiver or soundbar.

App-Driven Precision Control
Free WiiM Home App gives 10-band parametric EQ, crossover, phase & latency tweaks, plus firmware updates that keep improving your sound.

Seamless WiiM & Multi-Room Integration
Pairs wirelessly with WiiM streamers, amps and speakers or joins any multi-room group, filling every corner with synchronised, cinema-grade bass.

Please Note: When using the WiiM Sub Pro in wireless mode, a temporary limitation may prevent bass output during playback of Alexa Multi-Room Music, Roon Ready, LMS, and Google Cast. WiiM is actively working on a resolution for this.
