Introducing Minirig Subwoofer 4 with our most significant improvements to date. We have invested years of dedicated Research and Development to refine the design, delivering enhanced power and precise control over the custom 3-inch double neodymium driver. Furthermore, we’ve boosted the battery capacity from 28Wh to 33.3Wh.

The true power, however, lies in its connectivity: experience a complete modular wireless system by effortlessly linking the Sub 4 to multiple Minirig 4 speakers and Subwoofer 4s via Bluetooth. These internal upgrades are complemented by USB-C charging and full app control for detailed gain and EQ settings. This evolution results in what we confidently believe is the best, smallest portable subwoofer on the market.
