On the go with the Kilburn II. This portable Bluetooth speaker offers over 20 hours of playtime on a single charge - without the hassle of cables. The adventurer weighs just 2.5 kg and is the loudest in its class. It offers clear mids, deep bass and extended treble that is hard to find on a speaker of this size. The Kilburn II uses True Stereophonic, a unique form of multi-directional sounds from Marshall. Experience absolute 360° sound that is optimal from any point of view. The Kilburn II embodies the legacy of rock 'n' roll: the solid metal grid pays homage to the steel mesh found on many classic microphones, and its electric guitar-inspired carrying strap makes it easy to carry. With the flush mounted corner caps and waterproof design, it is particularly robust and durable. The Kilburn II withstands even the toughest demands of life on the go.
