These are not really the same size class, and that is the honest framing here. The B&O Beosound 2 ranks #5 of 5 powered desktop speakers by sound quality at $4000; the JBL Authentics 300 ranks #32 of 75 boombox speakers by sound quality at $299.95.

The case for the B&O Beosound 2: A beautifully made, compact Wi-Fi speaker with omnidirectional playback, Chromecast, AirPlay, Bluetooth with AAC/aptX, optical and aux inputs, app EQ, voice control and Beolink multiroom. The tradeoff: Its bass-forward balance can recess the mids, and its 94dB maximum level is modest for a speaker intended to fill larger spaces.
The case for the JBL Authentics 300: Integrates both Amazon Alexa and Google Assistant simultaneously (rare for smart speakers). The tradeoff: Narrow sounding, bass not as deep as others.
Buy the B&O Beosound 2 at $4000 for a powered desktop speaker, or the JBL Authentics 300 at $299.95 for a boombox speaker instead.

The Two Speakers In Full
B&O Beosound 2: $4,000.00 each Amazon eBay
Pros: A beautifully made, compact Wi-Fi speaker with omnidirectional playback, Chromecast, AirPlay, Bluetooth with AAC/aptX, optical and aux inputs, app EQ, voice control and Beolink multiroom. Reviews praise its even scaling at low volume, spacious room-filling presentation and convincing bass for a single 4.1kg enclosure. Measured bass extension of ~45Hz (-10dB).
Cons: Its bass-forward balance can recess the mids, and its 94dB maximum level is modest for a speaker intended to fill larger spaces. There is no battery or water rating, so this is a mains-powered indoor product; its luxury design and streaming feature set matter more than outright value or neutral hi-fi accuracy.
