Compact Size, Serious Bass:

The Minirig Subwoofer 4 proves that outstanding bass performance does not require a large enclosure. Measuring just 219mm high and weighing only 1051g, it is easy to carry while producing impressively deep frequencies down to 38Hz. The redesigned 74mm high excursion driver, paired with a powerful double neodymium motor system and efficient 50W RMS amplifier, delivers greater control, precision, and punch across every listening session. Whether you are enjoying music indoors or outdoors, the Subwoofer 4 adds the low-frequency foundation that smaller speakers simply cannot reproduce on their own.

Advanced Wireless Connectivity:

The biggest advancement in the Minirig Subwoofer 4 is its fully integrated wireless connectivity. Designed to work seamlessly with Minirig 4 and Minirig Mini speakers, it allows you to create a scalable Bluetooth sound system without relying on physical cables. Bluetooth 5.0 with AAC ensures reliable wireless audio, while Linkup mode and wireless stereo provide flexible listening options. The dedicated Minirig app gives complete control over gain and EQ settings, allowing you to optimise bass output for different rooms, outdoor spaces or personal listening preferences.

Built for Long Lasting Performance:

Every aspect of the Minirig Subwoofer 4 has been engineered for durability and convenience. The premium anodised aluminium body and high-impact ABS construction offer excellent protection while maintaining a lightweight design. The upgraded 33.3Wh battery delivers up to 100 hours of playback at lower volumes, with USB-C Power Delivery reducing charging time to as little as two hours using a compatible fast charger. Additional features, including power bank functionality, over-the-air updates, integrated microphone, RGB LEDs and Bluetooth receiver mode, make it a versatile companion for portable audio enthusiasts.
