The Marshall Stanmore III is Marshall’s mid-size home Bluetooth speaker, positioned between the smaller Acton III and larger Woburn III in the Home Line lineup with the same guitar-amp aesthetic Marshall built its brand around. A two-way driver system with a 5.25-inch woofer and dual outward-angled tweeters produces 80W of amplification through the leather-wrapped cabinet. Bluetooth 5.2 supports the wireless connection to phones, and RCA and 3.5mm AUX inputs on the back accept a turntable or a direct wired source.

A portable Bluetooth speaker fit for a rockstar
Guitar amps are what Marshall built its brand on, and the Stanmore III wears that heritage on its sleeve with a leatherette-wrapped cabinet, script logo across the front grille, and a brass control panel on top. The physical controls on that brass panel manage source selection, volume, bass, treble, playback, and skip functions without needing to open an app. A brass power toggle on top powers the speaker on and off with a satisfying click. The overall look reads as an oversized combo amp.
The Stanmore III is made up of a two-way driver system consisting of one 5.25-inch woofer and two 0.75-inch dome tweeters that are powered by three class-D amplifiers for an overall output of 80W. In contrast to the tweeters being mounted side-by-side in the previous generation, they are angled outward from the center axis in the third generation, resulting in a larger soundstage than before. Dynamic Loudness processing keeps the tonality of your music consistent even when you have it turned down, maintaining full low-end response while preventing clipping during loud moments.
