Short answer: the Marshall Stockwell II. It ranks #11 of 102 large speakers by sound quality, rated 4.5/5, at $229.99; the Turtlebox Cub ranks #77, rated 3.0/5, and costs $330, which makes this an easy call rather than a real tradeoff.
The Marshall Stockwell II is the better-sounding, longer-running pick. Possibly the most natural sounding Marshall speaker, with excellent off-axis sound. It is rated for 20 hours of battery against 14 for the Turtlebox Cub. At 3.1 lbs (1.4 kg) it weighs much less than the Turtlebox Cub at 5.3 lbs (2.4 kg). The tradeoff: Not very loud, and the added DSP reverb may annoy purists.
The Turtlebox Cub is the tougher option. 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 is rated IP67 against IPX4 for the Marshall Stockwell II. It links with other speakers (Party Mode), which the Marshall Stockwell II cannot. The tradeoff: The evidence so far is listening impressions from two reviews, with no side by side tests against other brands.
Buy the Marshall Stockwell II. It is rated higher for sound quality than the Turtlebox Cub and costs less, so only choose the other one for a particular feature it does better.

The Two Speakers In Full
Marshall Stockwell II: $229.99 Amazon eBay
Newer model: the Marshall Stockwell III, ranked lower, rated 3/5.
Pros: Marshall Stockwell II uses 3” woofer, 2x 2” fullrange tweeters. Its 1.4 kg, claimed 20 hours (Manufacturer specified) battery life, IPX4 protection, aux input, up to 96dB and mono playback make it a practical option for its intended room or portable use. Possibly the most natural sounding Marshall speaker, with excellent off-axis sound. Measured bass extension of 44Hz (-10dB).
Cons: Bass is limited by its 44Hz specification. There is no companion app. No EQ adjustment. Not very loud, and the added DSP reverb may annoy purists.

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.
