The WiiM Sub Pro is a wireless subwoofer built to add depth and weight to both music and home theatre systems. A 250W Class-D amplifier drives a custom 8-inch woofer, delivering clean, controlled bass down to 25 Hz. Rather than relying on brute force, the Sub Pro uses AI-driven RoomFit calibration to analyse your room acoustics and speaker placement, then tunes its output so the bass stays balanced wherever you sit.
Connectivity is where the Sub Pro stands apart from conventional subwoofers. It pairs wirelessly with WiiM streamers, amplifiers, and speakers over Wi-Fi 6, and an RCA mono input lets it connect to almost any third-party receiver, amplifier, or soundbar with a subwoofer output. Everything is managed through the WiiM Home App, giving you full control over EQ, crossover, phase, level, and latency without touching the unit.

Why Consider the WiiM Sub Pro
Most subwoofers force you to choose between wireless convenience and proper tuning control, but the Sub Pro offers both. It slots effortlessly into an existing WiiM ecosystem for a cable-free 2.1 or 5.1 setup, yet the RCA input means it works just as well with a traditional AV receiver or stereo amplifier. RoomFit takes the guesswork out of placement, and the app gives you room to refine the sound as much as you want. For anyone building a modern, app-controlled system, it is a flexible and future-proof choice.
Ideal For
- WiiM owners completing a wireless 2.1 or 5.1 system
- Home theatre setups needing controlled, cinematic low end
- Music listeners who want tuneful rather than boomy bass
- Anyone who prefers full app control over their subwoofer
