Overview
Connecting wirelessly rather than through a subwoofer cable, the WiiM Sub Pro is a floor-standing subwoofer with a 250 watt amplifier and 12.7 inch driver. It measures 15.7 x 11.8 x 12.7 inches and weighs 35.2 pounds in black.
Because it links wirelessly instead of through a subwoofer cable, this sub is built to pair with WiiM's other wireless audio gear, such as its soundbars or amps, without running a wire across the room. The floor-standing design and 35 pound weight point to a permanent placement rather than something moved often.

Who it's for
Owners of WiiM's wireless audio components looking for a matching subwoofer without a cable run, or anyone who simply prioritizes wireless bass over a wired connection, are the intended buyer. Lowest possible latency of a hardwired sub is not what this delivers.
Strengths and trade-offs
Drawn from this product's published specifications.
- Wireless Bluetooth and Wi-Fi pairing
- Large 12.7 in driver
- 250 watt power rating
- Heavy at 35.2 lb
- Wireless connection may add slight latency versus wired
Performance notes
The 12.7 inch driver and 250 watt power rating are sized for real low-frequency output in a living room rather than background bass, and Bluetooth or Wi-Fi pairing removes the need to route a cable back to a receiver. Wireless subwoofers can introduce a small amount of latency compared to wired ones, though WiiM's platform is built specifically around this kind of pairing.
