Marshall upgrades the bass and can repair two wireless speakers

Marshall announced new versions of its Acton and Stanmore Bluetooth speakers today with upgraded tweeters, bass ports and internal designs that improve their ability to fill a room with sound. The Acton IV and Stanmore IV replace their four-year-old predecessors with a new focus on repairability. Parts including the knobs, feet and front grilles of the speakers bearing the iconic Marshall logo are replaceable if damaged.

The smaller Acton IV, which features a 4-inch woofer and a pair of 0.75-inch woofers, is available starting today for $299.99 through Marshall online store. The Stanmore IV, which has a similar driver setup but with a larger 5-inch woofer, is priced at $399.99. Both speakers feature redesigned bass ports with a “more aerodynamic shape” that produces “cleaner, stronger bass,” according to a statement from Marshall. Their power cords are also now connected to the bottom of the speakers instead of the back, so the Acton IV and Stanmore IV can be used while placed on a wall.

New speakers carry support for Auracast Bluetooth featuremaking it easy to connect and sync music playback across multiple units, and they both work with it Marshall’s Heddon Wi-Fi Broadcast Center Which launched in January. The hub can connect directly to streaming services like Spotify Connect and Tidal (streaming Apple Music requires a smartphone) and stream audio to an Acton IV, Stanmore IV, or any Auracast-enabled Bluetooth speaker.
