Connection Mode

The WiiM Sub Pro is a wireless smart subwoofer designed to deliver deep, distortion-free bass to your audio system. The WiiM Sub Pro seamlessly integrates with WiiM devices to unlock wireless streaming capabilities and smart features for a personalized listening experience. It can also connect to specific WiiM devices or third-party audio systems via an RCA cable, offering flexible installation options.
