The Marshall Stanmore III is a powerful home speaker designed to fill larger rooms with rich, balanced sound. It utilizes a 2.1 channel acoustic system featuring three-way speakers, where a 50 W subwoofer handles the low end and two 15 W high-frequency drivers manage the treble, resulting in a total RMS power of 80 W. This configuration allows for a wide frequency response ranging from 45 Hz to 20,000 Hz, ensuring that both deep bass and crisp highs are clearly audible. Constructed from a blend of plastic and metal, the speaker maintains the brand's iconic aesthetic while weighing 4.25 kg. Its dimensions of 35 cm in width, 20.3 cm in height, and 18.8 cm in depth make it a substantial presence on a sideboard or desk. For connectivity, you can use Bluetooth 5.2 with SBC codec support, a 3.5 mm mini Jack AUX input, or RCA ports to connect your favorite audio sources. You can manage playback through the physical controls for volume and source selection or via the Marshall Bluetooth app. The inclusion of multi-speaker pairing allows you to expand your sound setup across different rooms. While it primarily relies on an external power adapter for mains electricity, this model also offers 20 hours of battery life and IPX4 water resistance, making it more versatile for different home environments.
