Marshall Acton III vs Klipsch The One II: Which Is Better? (2026)

Q: Should I buy the Marshall Acton III or the Klipsch The One II?

Buy the Marshall Acton III for app-based tone adjustment and the more capable listed driver array. Buy the Klipsch The One II for optical, USB, RCA, and aux inputs at a lower entry point.

Short answer: the Marshall Acton III is the better choice for app control and slightly deeper claimed bass, while the Klipsch The One II is the source-flexible bargain. Marshall’s 60W system uses two dome tweeters and reaches a claimed 45Hz, compared with Klipsch’s 50W, 50Hz specification.

Neither is battery powered or truly wide-stereo, so this is a desktop or shelf decision. The Acton supports bass and treble adjustment through an app plus aux input. The Klipsch drops the app but adds RCA, optical, and USB alongside Bluetooth and aux, which is meaningful for TV, turntable, or computer setups.

Buy the Marshall Acton III for app-based tone adjustment and the more capable listed driver array.

Buy the Klipsch The One II for optical, USB, RCA, and aux inputs at a lower entry point.
