The bass range is the foundation of any audiophile experience. Precise, powerful bass can bring music and movies to life, while uncontrolled booming can quickly spoil the overall listening experience. With the Sub Pro, WiiM, the manufacturer known for its smart streaming solutions, is now presenting its first subwoofer, which promises to usher in a new era of bass reproduction thanks to intelligent technology and powerful hardware.
Technical sophistication meets intelligent control
The WiiM Sub Pro is far more than just another bass speaker. At the heart of this compact powerhouse is a specially developed 8-inch long-throw woofer driven by a powerful 250-watt Class D power amplifier. This combination enables the subwoofer to reproduce frequencies down to an impressive 25 Hz, providing a noticeable and deep bass foundation. The technical data is promising and indicates a performance that you would otherwise only expect from much larger and more expensive models.
| Feature | Specification |
|---|---|
| Driver | 8-inch custom woofer |
| Amplifier power | 250 W RMS (Class-D) |
| Frequency response | 25-200 Hz |
| Connectivity | Wi-Fi 6, Bluetooth 5.3, Ethernet, RCA Mono In |
| Special features | AI RoomFit™, app control, 10-band EQ |
However, the real innovation of the Sub Pro lies in its intelligent side. With AI RoomFit™ technology, WiiM offers automatic room calibration that adapts the frequency response of the subwoofer to the acoustic conditions of the listening room. The subwoofer is calibrated via the WiiM Home app to minimize booming frequencies and standing waves - a feature that was previously often reserved for more expensive high-end devices. In practice, this means a much more precise and homogeneous bass that blends seamlessly into the sound of the main speakers.
Seamless integration and flexible use
As you would expect from WiiM, the focus is on user-friendliness. The Sub Pro can be integrated into any existing setup either wirelessly via Wi-Fi 6 or classically via cable (RCA Mono In, Ethernet). Setup and control are carried out entirely via the intuitive WiiM Home app. Here, users can not only adjust the volume and crossover frequency, but also access a 10-band equalizer, phase and latency settings. These extensive intervention options allow perfect tuning to personal preferences and the existing chain.
In the listening test, the WiiM Sub Pro delivered an impressive performance. In music with complex bass lines, such as Yello or Daft Punk, it reproduces the low tones precisely and contoured without being intrusive. It also provides the necessary foundation for action-packed movie scenes and creates an immersive atmosphere that puts the viewer right in the middle of the action. The AI RoomFit™ calibration does a great job here and ensures remarkably clean and dry bass reproduction, even in acoustically demanding rooms.
Conclusion: An intelligent bass revolution?
The WiiM Sub Pro is an impressive first for the company in the subwoofer segment. It combines powerful hardware with intelligent features at an extremely attractive price-performance ratio. Especially for owners of a WiiM amp or other WiiM components, the Sub Pro is a logical and sonically convincing addition. But it is also a clear recommendation as an upgrade for existing stereo or home cinema setups thanks to its flexible connection and excellent room calibration. The WiiM Sub Pro is proof that smart, precise and powerful bass doesn't have to be prohibitively expensive.
