Marshall upgrades bass and repairability in Acton IV and Stanmore IV Bluetooth speakers

Marshall has unveiled its latest Bluetooth speakers, the Acton IV and Stanmore IV, featuring enhanced bass and improved repairability. Announced on July 7, 2026, these new models focus on sustainability by allowing users to replace several components, including knobs and the iconic front grills, should they become damaged.

Upgraded Features of Acton IV and Stanmore IV

Both the Acton IV and Stanmore IV come equipped with upgraded tweeters and bass ports that enhance sound quality. The Acton IV features a 4-inch woofer and two 0.75-inch tweeters, while the larger Stanmore IV boasts a 5-inch woofer. According to Marshall, these upgrades result in "cleaner and more powerful bass."

Pricing for the Acton IV starts at $299.99, while the Stanmore IV is available for $399.99. Both models are now available for purchase through Marshall’s online store.

Improved Design for Optimal Use

The design of the new speakers has been optimized for better usability. The power cords now connect at the bottom of the speakers, allowing them to be placed flush against a wall. This feature is particularly beneficial for users with limited space.

Additionally, both models support the Bluetooth Auracast feature, enabling seamless connectivity and synchronized playback across multiple devices. They are also compatible with Marshall’s Heddon Wi-Fi streaming hub, which connects directly to streaming services like Spotify and Tidal.

Focus on Repairability

Marshall's commitment to repairability is evident in the design of the Acton IV and Stanmore IV. Users can easily replace parts such as:

• Knobs
• Feet
• Front grills

This initiative not only extends the lifespan of the speakers but also aligns with growing consumer demand for sustainable electronics.
