Developments: 8. Marshall’s June–July rollout of new Bluetooth speakers continued into mid‑July. On 12 July the company confirmed the official launch of the Acton IV and Stanmore IV home speakers, reiterating the €299 and €399 price points for black or cream finishes in Europe. Both models retain the retro vinyl‑style grille and brass knobs, now equipped with upgraded tweeters, optimized waveguides, revised bass geometry, the Dynamic Loudness system, Auracast™ multi‑room linking, LDAC high‑resolution Bluetooth, and a companion app for EQ and placement adjustments. They also continue the interchangeable‑component, repair‑friendly design using FSC‑certified wood. The same period saw a price reduction for the Emberton III portable speaker, now offered just under €130 in Europe while keeping its IP67 rating, 32‑hour battery life and guitar‑amp aesthetic. On 26 July Marshall marked the 60th anniversary of Jimi Hendrix’s partnership with a limited‑edition Action III speaker. The compact unit, finished in a distinctive purple‑black hue, features Bluetooth and AUX connectivity, dual 15 W class‑D tweeters, a 30 W class‑D subwoofer, and must be mains‑powered. The release includes complementary merchandise such as T‑shirts and a guitar‑amp head, extending the brand’s heritage‑focused promotion. These developments broaden Marshall’s Bluetooth‑speaker portfolio across home, portable, and special‑edition segments, adding pricing clarity, new acoustic enhancements, and heritage‑driven product launches. ## Timeline ### 2026-07-26: Marshall launches Hendrix‑anniversary Action III speaker Marshall, the legendary UK amp maker, honored Jimi Hendrix with a limited‑edition purple‑black Action III speaker featuring Bluetooth, 15 W tweeters, a 30 W sub, and related merchandise. 2 sources. https://clstr.news/cluster/marshall-launches-hendrixanniversary-action-iii-speaker ### 2026-07-12: Marshall launches Acton IV and Stanmore IV speakers with improved sound and Auracast Marshall’s Acton IV and Stanmore IV speakers launch with upgraded tweeters, better bass, Auracast multi‑room Bluetooth, LDAC support, and prices of €299 and €399. 3 sources. https://clstr.news/cluster/marshall-launches-acton-iv-and-stanmore-iv-speakers-with-improved-sound-and-auracast ### 2026-07-10: Marshall unveils Acton IV and Stanmore IV speakers, cuts Emberton III price Marshall launched Acton IV and Stanmore IV home Bluetooth speakers with upgraded sound and repairable parts, priced €299/€399, and lowered the Emberton III portable speaker price to around €130. 2 sources. https://clstr.news/cluster/marshall-unveils-acton-iv-and-stanmore-iv-speakers-cuts-emberton-iii-price ### 2026-07-06: Marshall launches Acton IV and Stanmore IV home speakers Marshall unveils Acton IV and Stanmore IV speakers with upgraded tweeters, LDAC, RCA input, Auracast multi‑room sync and a customizable “M” button; prices start at £260/£350. 6 sources. https://clstr.news/cluster/marshall-rolls-out-acton-iv-speaker-and-minor-iv-earbuds-with-new-audio-upgrades ### 2026-07-01: Marshall launches Bromley 450 compact party speaker Marshall introduced the Bromley 450 portable party speaker with 360° sound, 40+ hrs battery, stage lights, IP55 rating, priced at ₹79,999 and on sale from July 2; 1% of purchases aid grassroots music venues. 3 sources. https://clstr.news/cluster/marshall-launches-bromley-450-compact-party-speaker ### 2026-06-24: Marshall Emberton III Bluetooth Speaker Discounted on Amazon Prime Day Amazon Prime Day discounts the Marshall Emberton III Bluetooth speaker to $99.99 in the US and under €130 in Germany; the unit features 32‑hour battery life, IP67 rating, and Marshall’s signature sound. 2 sources. https://clstr.news/cluster/marshall-emberton-iii-bluetooth-speaker-discounted-on-amazon-prime-day ### 2026-06-10: Marshall launches Stockwell III Bluetooth speaker with 40‑hour battery life Marshall unveiled the Stockwell III portable speaker, adding a user‑replaceable 40‑hour battery, IP55 protection, True Stereophonic sound and power‑bank capability; priced at $249.99 US and A$359 AU. 2 sources. https://clstr.news/cluster/marshall-launches-stockwell-iii-bluetooth-speaker-with-40hour-battery-life ### 2026-06-09: Marshall launches Stockwell III portable Bluetooth speaker with 40‑hour battery Marshall unveiled the Stockwell III portable Bluetooth speaker, offering 40‑hour battery life, IP55 protection, True Stereophonic 360° sound, modular replaceable parts and a USB‑C power‑bank feature, priced at 5 sources. https://clstr.news/cluster/marshall-unveils-stockwell-iii-portable-speaker-with-40hour-battery-and-360-sound --- Cite as: Marshall Bluetooth speaker lineup updates.
