Sonos Sub Mini
Score: 76/100
Marshall Acton III Midnight Blue
Score: 77/100Rankings

The midnight-blue Acton III offers the same 60 W RMS performance as its black counterpart, wrapped in a stylish, eco-friendly cabinet with tactile analog controls. It excels in Bluetooth convenience and sound quality for modest spaces, but lacks advanced codecs, Wi-Fi, and any form of portability.

The Sonos Sub Mini is a compact, wireless subwoofer that adds surprisingly deep bass to Sonos setups, ideal for small-to-medium rooms.

“automatic reconnection when moved”




Professional reviewers praise the Acton III for its premium build, iconic brass knobs, and warm, detailed sound signature that stays true to Marshall's rock heritage. They also commend the Placement Compensation and Dynamic Loudness features delivered through the Marshall app, but criticize the lack of advanced Bluetooth codecs and consider the price high for the feature set.
Everyday users love the speaker's ability to fill modest spaces with rich audio, its eye-catching vintage look, and the tactile satisfaction of the analog knobs. Common complaints revolve around the missing AAC codec on iOS, occasional app instability, overpowering bass at high volumes, and the absence of a battery for portable use.
