Heavyweight Sound. Road-Ready & Built to Last.

Take the stage wherever life leads you. The Marshall Stockwell III combines iconic stage-amp aesthetics with modern audio engineering, delivering a massive soundstage from a compact, travel-friendly package. Styled with Marshall’s signature brass-accented control panel, tactile knobs, and a plush carrying strap, the Stockwell III isn't just a portable speaker—it's a rock 'n' roll lifestyle essential.

Engineered with sustainability and longevity in mind, the Stockwell III introduces a modular, user-repairable design featuring an exchangeable battery, ensuring your speaker stays on the road for years to come.

Key Features

• 40+ Hours of Unstoppable Playtime: Keep the music rolling from sunrise to far beyond midnight. A single charge delivers over 40 hours of continuous wireless playback—making it the ultimate companion for long weekend road trips, camping, and outdoor sessions.

• True Stereophonic 360° Sound: Marshall's unique multi-directional sound signature ensures complete room coverage. By emitting balanced, full-range audio from both front and back, every listener experiences the same rich, immersive sound profile no matter where they stand.

• Power Bank Mode (USB-C Power Out): Don't let a dead phone battery kill the vibe. The Stockwell III acts as an emergency power bank, letting you plug in your smartphone or wireless earbuds via USB-C to top off their battery while keeping your playlist rolling.

• Built for the Elements (IP55 Rating): Rain, dust, or accidental drink spills won't stop the show. Rated IP55 for dust and water resistance, it’s tough enough to handle everyday knocks and outdoor environments with absolute confidence.

• Dynamic Loudness & Custom EQ: Enjoy punchy, balanced audio at any level. Dynamic Loudness automatically adjusts the treble and bass response so low-volume listening retains full acoustic detail, while physical brass knobs allow you to fine-tune your sound manually.

• Bluetooth 5.3 with Auracast™: Built on future-ready Bluetooth architecture supporting high-quality codecs and Auracast multi-speaker broadcast capabilities, allowing you to stream seamlessly across compatible devices with minimal latency.

Perfect For:

• Travelers & Outdoor Enthusiasts: The combination of a 40+ hour battery, carrying strap, and IP55 weather resistance makes it ideal for life on the move.
