Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The B&O Beosound 2 ranks #5 of 5 powered desktop speakers by sound quality at $4000; the Brane X ranks #4 of 78 large speakers by sound quality at $500.
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 Brane X: The Brane X pairs a dedicated RAD subwoofer with two midrange drivers and two tweeters to achieve extraordinary low bass for a 3.5kg portable: its measured -10dB extension is 31Hz. The tradeoff: The front-facing design has only moderate dispersion, so sound changes noticeably off to the sides or behind it.
Buy the B&O Beosound 2 ($4000) for a powered desktop speaker; the Brane X ($500) suits a large 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.

Brane X: $500 Amazon eBay
Pros: The Brane X pairs a dedicated RAD subwoofer with two midrange drivers and two tweeters to achieve extraordinary low bass for a 3.5kg portable: its measured -10dB extension is 31Hz. Independent testing finds it loud, with well-balanced mids, a smooth treble balance and useful bass-level controls; Wi-Fi, AirPlay, Alexa, quality Bluetooth codecs and low-latency aux pass-through make it unusually versatile. Measured bass extension of 31Hz (-10dB).
Cons: The front-facing design has only moderate dispersion, so sound changes noticeably off to the sides or behind it. Bass response shifts at maximum volume, the default aux mode has very high latency, and some listeners find the upper register edgy or need EQ to achieve their preferred balance. Its claimed 12-hour runtime and premium cost make it more of a compact high-end system than a carefree all-day speaker.
