Vizio SB3620n-H6
Score: 60/100
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 VIZIO SB3620n-H6 is a compact 2.0-channel sound bar that adds virtual surround with DTS Virtual:X and dialogue enhancement to small-to-medium rooms. It offers HDMI-ARC, Bluetooth 5.0, and voice-assistant support in a sub-$100 package, but lacks a subwoofer and smart Wi-Fi features.

Products in the top-left offer the best value (high score, low price).

Professional reviewers praise the V20-J8 for delivering surprising spatial audio and dialogue clarity at a budget price, noting its reliable HDMI-ARC and solid construction. However, they point out the design trade-off of omitting a subwoofer and smart Wi-Fi features, making it less appealing for audiophiles or large-room setups.
Everyday users rate the bar highly for its sound improvement over TV speakers, ease of installation, and useful dialogue mode. Common complaints focus on the thin bass response, occasional echo with optical audio, and the non-backlit remote.

“Game-changer for dialogue clarity”

“Easy setup, works right away”

“No deep bass”




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.
