The Marshall Kilburn II is a portable Bluetooth speaker designed for those who want a rich, stereo sound experience they can carry with them. It delivers a total output of 36 W through a two-way system, combining two 8 W speakers with a 20 W driver to cover a frequency range from 52 Hz to 20,000 Hz. You can connect your devices via Bluetooth 5.0 using SBC or aptX codecs, or use the 3.5 mm auxiliary input for a wired connection. Wrapped in a blend of wood and synthetic leather, the speaker features a classic horizontal design and a sturdy carrying strap for easier transport. Its physical interface consists of analog knobs that let you manually adjust the volume, bass, and treble to suit your listening preference. Weighing approximately 2.5 kg and measuring 24.3 cm by 16.2 cm by 14 cm, it balances a substantial build with portability. The internal lithium-ion battery provides up to 20 hours of playback on a single charge, while an IPX2 rating offers basic protection against light splashes, making it a reliable companion for indoor and outdoor gatherings.
