Marshall has officially launched the Stockwell III, a third-generation portable speaker featuring a 40-hour battery life and an IP55-rated durable design. According to the manufacturer, the device introduces True Stereophonic 360-degree sound and modular components intended to increase product lifespan. The speaker retails for 2,499 SEK, with an initial release on Marshall.com followed by retail availability.
How does the Stockwell III improve upon previous battery standards?
The most significant technical shift in the Stockwell III is its 40-hour battery capacity. Marshall reports this is double the runtime of its predecessor, the Stockwell II. This shift aligns with broader industry trends toward extended power efficiency in portable audio, where manufacturers are increasingly prioritizing long-haul reliability over ultra-compact, short-battery designs. By integrating a USB-C port that functions as a power bank, Marshall allows users to charge external mobile devices using the speaker’s internal battery, a feature common in high-end portable power solutions.
What is the significance of the “Dynamic Loudness” feature?
Marshall has introduced “Dynamic Loudness” to address the common audio quality drop-off experienced at low volumes. According to technical specifications provided by the company, this feature automatically adjusts the balance of bass and treble as volume levels fluctuate. This ensures that the acoustic profile remains consistent whether the speaker is playing at a low level in a quiet room or at maximum output during a social gathering. This functionality aims to solve a long-standing issue in portable audio: the tendency for sound to lose “fullness” when the decibel level is turned down.
How does the design impact durability and usability?
The Stockwell III features an IP55 rating, certifying protection against dust ingress and water splashes. Unlike the previous generation, the new model adopts a vertical orientation, which Marshall claims improves portability while maintaining the brand’s signature guitar-amp aesthetic. The top control panel has been refined to include more tactile knobs and a dedicated “M-button,” which provides users with faster access to custom presets. These physical upgrades reflect a shift toward more intuitive, hardware-based control interfaces rather than relying exclusively on smartphone app integration.
