The Kilburn III is Marshall's mid-size portable Bluetooth speaker, built around a 4-inch woofer, two tweeters and a bass-reflex cabinet. It stands out with physical bass and treble knobs, a media jog dial and the M-button for recalling EQ presets, plus Bluetooth 5.3, an aux input and USB charging for a phone. It suits people who want room-filling rock-friendly sound and Marshall's amp-style look in a grab-and-go box. Against rivals like the JBL Charge and Sonos Roam it trades smart features and a speakerphone for tactile controls and a bigger, warmer sound.
