FAQs 

How do I connect the WiiM Sub Pro to my system? 
You can connect wirelessly to WiiM streamers, amplifiers, and speakers, or use the RCA input for any third-party device with a subwoofer output. 

Can I use the WiiM Sub Pro with non-WiiM audio gear? 
Yes. The Sub Pro works with any receiver, amp, or soundbar that has a standard RCA subwoofer output. 

Is the WiiM Sub Pro truly wireless? 
Yes. It supports wireless pairing with compatible WiiM devices via Wi-Fi 6 (and Bluetooth 5.3 via software update). No cables are required for signal transmission in those setups — just power. 

Does it support multi-room audio? 
Yes. When connected wirelessly to a WiiM device, the Sub Pro can sync as part of a multi-room setup via the WiiM Home App. 

How does RoomFit™ auto-calibration work? 
RoomFit™ uses your mobile device’s microphone or external one attached to your mobile device to analyze your room acoustics, then automatically adjusts bass output for optimal performance. 

Can I fine-tune bass settings manually? 
Absolutely. The WiiM Home App lets you adjust EQ, crossover frequency, phase, level, and latency for custom sound tuning. 

What’s the benefit of Wi-Fi 6 and Bluetooth 5.3? 
Wi-Fi 6 ensures stable, high-bandwidth, low-latency wireless audio. Bluetooth 5.3 with LE Audio support provides low power consumption and improved streaming quality. 

Can I pair more than one Sub Pro in a setup? 
Yes. If using compatible WiiM streamers or amps with stereo pairing, you can assign a Sub Pro to each channel for a fully immersive 2.2 system.
