Soundcore Boom 2 vs W-King D9

Last updated: October 12, 2026

Short answer: the Soundcore Boom 2 has the better bass potential if you EQ it, while the W-King D9 is the endurance and input-feature option. Boom 2 produces deep bass for its size and has side passive-radiator lighting, but its stock tuning is boosted in bass and rising in treble.

Soundcore Boom 2 vs W-King D9

It benefits substantially from Oluv’s or Alan Ross’s EQ. With BassUp off, its limitations remain a single midrange driver, inconsistent low-level bass processing, and a bright treble lift of roughly 5dB.

D9 offers 60W RMS, a 106dB claim, a 40-hour battery, power bank, IPX6 protection, MicroSD, AUX, USB-C, and an EQ button. Its very rolled-off treble limits detail, even if the feature list is unusually strong.

Buy the Soundcore Boom 2 if you will apply a recommended EQ and want deeper, more refined bass potential.

Buy the W-King D9 if battery life, playback inputs, and rugged utility outrank treble detail.

If battery life is a priority, the W-King D9 is rated for 40 hours versus 24 hours for the Soundcore Boom 2.

Soundcore Boom 2 ranking card

Older model: the Soundcore Motion Boom (ranked lower, rated 4.5/5). See every Soundcore Boom generation.

Same family: the Soundcore Boom 2 Plus (larger model, rated 3.6/5).

Pros: 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. Measured bass extension of 47Hz (-10dB).

Cons: 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, which is best left off. A little bit of a bright tuning in the treble, about +5db.

W-King D9: $71.24 Amazon $71.24 eBay

W-King D9 ranking card

Pros: A compact 2kg boombox with 60W RMS output, a claimed 106dB maximum level, a measured 47Hz -10dB bass point, IPX6 protection, power-bank output, USB-C charging, aux and microSD playback. Long-term owners praise its loud, punchy character and useful indoor/outdoor voicing for casual outdoor listening. Measured bass extension of 47Hz (-10dB).

Cons: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume. There is no app or adjustable EQ, and its bass does not reach as deep as larger rivals, so it is better suited to energetic background music than neutral listening.
