Marshall Kilburn III
Score: 83/100Rankings

The Tribit StormBox Blast 2 is a high-power boombox-style speaker delivering up to 200 W output, IP67 durability, and 30 hours of battery life with rich app-controlled features. Its main drawbacks are the substantial weight and size, plus slow USB-C charging and directional sound. Best suited for party hosts and outdoor events where volume and features outweigh portability concerns.

The Marshall Kilburn III is a premium portable Bluetooth speaker delivering 50 W of tri-amp power and up to 50 hours of playback, highlighted by its robust IP54 construction and analog controls. Its considerable weight of 2.8 kg and ambiguous power-bank functionality are notable trade-offs. Ideal for users seeking loud, long-lasting sound in a durable, amp-styled design.
