[5] The Sonos One features two Class-D amplifiers, a woofer, a tweeter, and six far-field microphones.
The speaker communicates with the companion app and music streaming services through Wi-Fi.
The second generation of the Sonos One increased the memory, added Bluetooth Low Energy (which can not be used for audio playback) and updated the processor.
Based on the outside design and its functionality the SL version is the same as the Gen 2 but without microphones, making it incompatible with Alexa or Google Assistant.
The SL is intended as the replacement for the Play:1 speakers and addresses the concerns that some users have with smart technology.
