Marshall Stockwell III Cream Portable Bluetooth Speaker

The Marshall Stockwell III is a portable Bluetooth speaker in Cream colorway, delivering powerful True Stereophonic 360° sound from a compact, carry-anywhere form factor. It features a three-driver array — one 3-inch woofer and two 1.75-inch wide-band drivers — powered by three Class D amplifiers totaling 127 watts of peak output (65W woofer, 31W per wide-band). Frequency response spans 54–20,000 Hz with a sealed cabinet and passive radiator design.

The Stockwell III runs on Bluetooth 5.3 with Auracast support, multipoint connectivity for pairing two devices simultaneously, and a 10m/32.8ft wireless range. It also offers a 3.5mm AUX input and USB-C for both audio and charging. The top panel features heritage amp-inspired tactile brass controls including bass, treble, volume, a standalone power button, M-button for preset access, and a media jog dial. A dynamic loudness system maintains balanced bass and treble across all volume levels.

Battery life exceeds 40 hours on a single charge, with quick charging delivering 7 hours of playtime from just 20 minutes at 30W USB-C PD. The built-in charging bank lets you charge phones and other audio devices directly from the speaker via USB-C. The battery is consumer-replaceable, and the speaker supports the Marshall Bluetooth app for EQ and preset management.

Built to IP55 standards, the Stockwell III is dust-resistant and protected against water jets from all directions, making it suitable for both indoor and outdoor use.
