Classic Design with Modern Enhancements
One of the most striking features of the Marshall Kilburn III is its timeless design. Drawing inspiration from classic guitar amps, the speaker features textured vinyl covering, a solid metal grille, and the signature Marshall script logo. The gold-accented control knobs on top offer tactile control over volume, bass, and treble—adding to the analog charm that sets it apart from most plastic Bluetooth speakers on the market.
Despite its retro look, the Marshall Kilburn III is packed with modern features. The design includes a rugged build and water-resistant construction (IPX4 rating), making it durable enough for outdoor use without compromising its sleek appeal.
Powerful Sound That Fills Any Space
What really makes the Marshall Kilburn III shine is its exceptional sound quality. Equipped with three dedicated class D amplifiers powering dual tweeters and a subwoofer, it produces rich, multidirectional sound that feels immersive and balanced. The speaker boasts a frequency range of 60Hz – 20kHz and an output of 36 watts, delivering powerful audio without distortion—even at high volumes.
Thanks to the new multi-directional sound technology, the Marshall Kilburn III provides a wider soundstage, making it ideal for both indoor listening and open-air gatherings. Whether you’re enjoying classic rock, hip-hop, jazz, or podcasts, the speaker adapts beautifully with adjustable bass and treble dials.
Extended Battery Life for All-Day Playback
Another area where the Marshall Kilburn III excels is battery life. Marshall claims up to 20+ hours of portable playtime on a single charge, which easily outperforms many other speakers in its class. Additionally, the fast charging feature gives you 3 hours of playtime from just 20 minutes of charging.
The battery indicator on the top panel ensures you’re never caught off-guard, and the USB-C port makes charging convenient, whether at home or on the road.
Connectivity and Usability
The Marshall Kilburn III offers seamless Bluetooth 5.1 connectivity, delivering a stable and quick connection with minimal latency. It pairs effortlessly with smartphones, tablets, and laptops. While there’s no app required, the speaker is compatible with Marshall’s Bluetooth app for firmware updates and EQ customization.
It also includes a 3.5mm aux input for users who prefer a wired connection, giving it extra versatility. Pairing is intuitive, and once connected, the speaker remembers previously paired devices, making the user experience smooth and hassle-free.
Portability Without Compromise
Weighing just under 2.5 kg (5.5 lbs), the Marshall Kilburn III is built for travel. The vintage-style carry strap with a guitar-inspired design adds to its rugged charm while making it easy to transport. Whether you’re headed to a beach day, road trip, or backyard party, this speaker is built to move with you.
Thanks to its IPX4 rating, the Marshall Kilburn III can withstand splashes and light rain, so it’s well-suited for outdoor use. It’s not fully waterproof, but it’s durable enough for everyday adventures.
