Kilburn III: The legendary Marshall portable speaker goes to a record autonomy of 50 hours

Among the oldest products in the Marshall catalog, there are Kilburn II. Indeed, despite the fact that it is the most emblematic portable enclosure of the British brand, it has not been renewed since 2018. In the wake of its first sound bar Heston 120Marshall puts an end to a cycle by revealing the kilburn III. Both modernized, updated and improved, this iteration intends to make us forget its elder.

REXIVED Orders and IP54 certification

The Marshall Kilburn III is no exception to the aesthetics and dimensions of its big sister, but immediately stands out by better manufacturing quality. It minimizes assembly marks, incorporates a removable transport strap and introduces a new command interface. Its potentiometers are now supplemented by buttons dedicated to switching on, preselections and reading management.

We also notice a new acoustic grid placed on its rear side, as well as a Bass-Reflex vent repositioned a little lower. Going from an IPX2 to IP54 certification, the Kilburn III is also better suited to outdoor use. Nevertheless, if you are looking for a completely waterproof enclosure, it remains necessary to turn to the Emberton III Or Middletonas for IP67 certified.

Record autonomy and new sound signature

The most significant optimization is on the side of its battery. The kilburn III actually promises up to 50 hours of autonomy, against 20 h for the kilburn II. She therefore seems to be registered as the most enduring Marshall enclosure ever developed. In addition, its tone can now be set using an equalizer within the Marshall application, while a Bluetooth 5.3 receiver the audio makes its introduction (LC3 Codec, Auracast, etc.). Connective level, it retains its 3.5 mm mini-jack input and includes a USB-C port also dedicated to the load of an external device.

The enclosure is also subject to acoustic improvements. It retains its principle of 360 ° sound diffusion True Stereophonic, but adopts the Dynamic Loudness function, supposed to maintain dynamic stable at any volume. In addition, its frequency response now extends from 45 Hz to 20 kHz and its total amplification at 40 W, against 52 Hz – 20 kHz and 28 W for the kilburn II.

The portable speaker Marshall Kilburn III is currently available at a price of € 349, in Cream and Black & Brass finishes. If his little sister Kilburn II is still around € 200, this new model is already rather interesting in views of the modernizations provided.
