Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The B&O Beosound 2 ranks #7 of 10 powered desktop speakers by sound quality at $4,000; the Brane X ranks #4 of 117 large speakers by sound quality at $549.
The case for the B&O Beosound 2: A beautifully made luxury Wi-Fi speaker that fills a room in every direction, with Chromecast, AirPlay, optical input and 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 Brane X is the deeper-bass, battery-powered option. A portable speaker with extraordinarily deep bass for its size, plus Wi-Fi, AirPlay, Alexa and a low latency aux input. Its bass reaches about 31Hz before falling 10dB, against 45Hz for the B&O Beosound 2. Its battery is rated for 12 hours, while the B&O Beosound 2 needs an outlet. It supports aptX HD Bluetooth, which the B&O Beosound 2 lacks. Watch for: 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 ($4,000) for a powered desktop speaker; the Brane X ($549) suits a large speaker instead.
