The Rockster Cross 2 sounds nearly identical to the original Cross, fairly neutral with punchy bass, and measured about 101dB with EQ. The Cub has only listening impressions so far: loud for its size, warm and bass-forward, with some bass loss at high volume.
Toughness favors the Cub: IP67 and crush resistant against the Cross 2’s IPX5.
Features favor the Teufel: a 3.5mm aux input, a USB-C sound card, multipoint and a claimed 38 hours against 14+. Both have a power bank and stereo pairing.
They weigh the same, 2.4 kg. The Cross 2 is not sold in the US.

The Two Speakers In Full
Teufel Rockster Cross 2: €249.99 Teufel eBay
Older model: the Teufel Rockster Cross (rated 4.2/5).
Pros: Keeps the original Rockster Cross’s sound, which was fairly neutral and vocal focused with punchy, well controlled bass, and the new Teufel Go app EQ gets noticeably more bass punch out of it than the original could manage. Claimed battery life more than doubles to 38 hours, or 46 in Eco Mode. USB-C charging with a power bank output and a built-in USB-C sound card, a 3.5mm aux input, multipoint pairing, AAC, and Party Link for a true stereo pair or up to 100 current Teufel speakers.
Cons: It uses the same drivers and amplifier as the 2018 original, so without EQ the two sound almost identical, even at maximum volume, and it measured about the same 101dB. In a direct comparison it struggles somewhat against the Soundcore Boom 2. aptX was dropped, water protection is still only IPX5 (water jets, not submersion), Party Link does not work with the original Cross, and the app’s bass and treble controls are limited. It is not sold in the US.

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 measurements or 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.
