Marshall Stanmore III — Black, Single

The Marshall Stanmore III is a black mains-powered speaker for listening at home, combining a bass-reflex cabinet with a woofer and two tweeters. Its three Class D amplifiers are rated at 50 W for the woofer and 15 W for each tweeter. Those figures describe the manufacturer's amplifier ratings, not a separately established RMS acoustic-output specification. Bluetooth 5.2 supports wireless playback, while RCA and 3.5 mm inputs connect compatible analogue equipment. This model does not have the HDMI connection found on the larger Woburn III. Top-panel controls let you adjust volume, bass and treble directly, with further sound customisation and updates available through the Marshall Bluetooth app. Basic playback also works without the app. The Stanmore III has no Wi-Fi, microphone system or voice control, and the manufacturer does not specify water resistance. Its cabinet measures 350 mm wide, 203 mm high and 188 mm deep, with a weight of 4.25 kg. This listing includes one speaker, a mains lead and user and safety documentation; it is not a rechargeable portable speaker and signal cables are separate.
