Marshall releases Acton IV and Stanmore IV Bluetooth speakers with upgraded sound and repairable parts

Marshall announced today the launch of updated versions of its Acton IV and Stanmore IV Bluetooth speakers, highlighting upgraded tweeters, enhanced bass ports and revised internal architectures aimed at delivering fuller room‑filling sound. Both models replace the four‑year‑old predecessors and are designed with repairability in mind, featuring replaceable knobs, feet and front grills that bear the brand’s iconic logo.

The Acton IV is the smaller of the two, equipped with a 4‑inch woofer paired with a pair of 0.75‑inch tweeters, and is priced at $299.99. It becomes available immediately through Marshall’s online store. The Stanmore IV shares a comparable driver configuration but is built for larger spaces, incorporating the same modular components to facilitate easy part replacement should damage occur.

These releases underscore Marshall’s focus on sustainable product design while maintaining the performance standards expected of its speaker line. The new models are now on sale, with further details provided by The Verge.
