Short answer: the Soundcore Boom 2 if sound quality matters most, the W-King D9 if price matters most. The Soundcore Boom 2 ranks #10 of 77 large speakers at $99.99. The W-King D9 ranks #65 at $71.24, $28.75 cheaper.
What the Soundcore Boom 2 offers: Pretty deep bass for the size. Cool lights in the side passive radiators. For the best sound quality use Oluv’s EQ or Alan Ross’s EQ. With the stock tuning, this speaker would rank around #24, due to the boosted bass and rising treble. Watch for: Only a single midrange driver, so you only get stereo for the tweeters. Sound processing issues with inconsistent bass notes that disappear at low levels like the Soundcore Boom and Soundcore Boost, not great for listening at low levels. Quite bass heavy with BassUp turned on, I’d recommend turning it off. A little bit of a bright tuning in the treble, about +5db.
What the W-King D9 offers: 60W RMS output, 106dB max volume, exceptional 40-hour battery life, power bank function, IPX6 waterproof, MicroSD and AUX support, dual drivers with passive radiators, Bluetooth 5.3, USB-C charging, EQ button, shockproof design Watch for: Very rolled off treble.
Buy the Soundcore Boom 2 when sound quality outweighs the price for you, and the W-King D9 when the price outweighs sound quality instead.
Skip the W-King D9 if sound quality matters to you. It ranks near the bottom of the 77 large speakers.
If battery life is a priority, the W-King D9 is rated for 40 hours versus 24 hours for the Soundcore Boom 2.
