Short answer: the Authentics 200. It ranks #2 out of 13, ahead of the Stanmore III at #6, and costs $17 less.
The Authentics 200’s headline feature is WiFi streaming with simultaneous Alexa and Google Assistant support, something rare at its size according to its pros. Reviewers cited in its notes rate its sound as well balanced and close to the pricier Authentics 300, and it measured about 113dB at 1kHz on max volume, matching that bigger model despite its smaller cabinet. Its cons note bass isn’t as deep as others, there’s no TWS pairing, no IP rating, it isn’t as loud as some rivals, and it has no battery.
The Stanmore III is the simpler, wired-only option. Its inputs are limited to Bluetooth, RCA, and aux, with no WiFi and no smart assistant support. Its pros describe a practical 5 inch woofer plus 5 inch midrange and 2x 0.75 inch tweeter setup at 80W, but its cons flag the same kind of bass ceiling, limited by its 45Hz to 20kHz spec.
What the Authentics 200 adds:
- WiFi streaming via AirPlay, Chromecast, and Spotify Connect, alongside Alexa multi-room support.
- Simultaneous Alexa and Google Assistant, letting you use either voice assistant without choosing one.
- A passive radiator (6 inch, down-firing) working alongside its 5 inch full-range woofer.
Buy the Authentics 200 if smart speaker features and WiFi multi-room streaming matter to you, at a lower price than the Stanmore III.
Buy the Stanmore III if you just want a straightforward Bluetooth and aux speaker without WiFi or voice assistants in the mix.
