Short answer: the B&O Beosound Level on measured sound quality, the W-King D9 on price, though neither ranks well in its class. The B&O Beosound Level ranks #92 of 120 large speakers, rated 2.8/5, at $2,250. The W-King D9 ranks #98, rated 2.5/5, at $89.98, $2,160.02 cheaper. Both are rated below 3.0/5 among the 120 large speakers; for better sound, the JBL Xtreme 5 ranks #2 at $399.95.
Why pick the B&O Beosound Level: A sculptural luxury speaker that works on battery or mains, mounts on a wall, and streams over Wi-Fi with upgradeable modules. Watch for: Not very deep bass, peaks in midrange.
The W-King D9 is the deeper-bass, longer-running option. A compact, punchy boombox with a very long rated battery, water resistance, and power bank output for casual outdoor use. Its bass reaches about 47Hz before falling 10dB, against 60Hz for the B&O Beosound Level. It is rated for 40 hours of battery against 16 for the B&O Beosound Level. At 4.4 lbs (2 kg) it weighs much less than the B&O Beosound Level at 7.3 lbs (3.3 kg). The tradeoff: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume.
