Short answer: the Turtlebox Cub on measured sound quality, the W-King D9 on price. The Turtlebox Cub ranks #77 of 102 large speakers, rated 3.0/5, at $330. The W-King D9 ranks #89, rated 2.5/5, at $71.24, $258.76 cheaper.
The Turtlebox Cub is the better-sounding choice. A compact, cube-shaped Turtlebox at 5.3 lbs (2.4 kg) with a real two-way layout: a 4.5 inch woofer and a 1.3 inch titanium tweeter. It links with other speakers (Party Mode), which the W-King D9 cannot. Watch for: The evidence so far is listening impressions from two reviews, with no side by side tests against other brands.
The W-King D9 is the longer-running option. A compact 4.4 lbs (2 kg) 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. It is rated for 40 hours of battery against 14 for the Turtlebox Cub. It plays in stereo from a single unit, unlike the Turtlebox Cub. The catch: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume.
Buy the Turtlebox Cub if sound quality is the priority over the price, or the W-King D9 if the price is the priority over sound quality.

The Two Speakers In Full
Turtlebox Cub: $330.00 Amazon eBay
Pros: A compact, cube-shaped Turtlebox at 2.4 kg with a real two-way layout: a 4.5 inch woofer and a 1.3 inch titanium tweeter. Reviewers found it very loud for its size, with warm, bass-forward tuning and a bit more bass than the Turtlebox Ranger. IP67 waterproof and dustproof, crush and drop resistant, stainless steel tie-downs, a claimed 14+ hours from a 49.95Wh battery, USB-C charging with a power bank output, stereo pairing and Party Mode.
Cons: The evidence so far is listening impressions from two reviews, with no side by side tests against other brands. One reviewer found it loses bass at high volume, and it is not as loud as the full-size Turtlebox. Turtlebox’s claimed 118dB is a figure the brand’s larger speakers have not come close to at a standard one meter distance. It is also mono from one unit, and its recessed USB-C port only fits slim cable plugs.

W-King D9: $71.24 Amazon eBay
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.
