Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Tribit Stormbox Blast ranks #2 of 113 boombox speakers by sound quality at $199.99; the Teufel Rockster Cross ranks #23 of 120 large speakers by sound quality at $199.99.
The Tribit Stormbox Blast is the deeper-bass, longer-running option. A boombox with bass and volume that rival bigger party speakers, quite neutral sound, and a 30 hour battery. Its bass reaches about 43Hz before falling 10dB, against 51Hz for the Teufel Rockster Cross. It is rated for 30 hours of battery against 16 for the Teufel Rockster Cross. It is rated IPX7 against IPX5 for the Teufel Rockster Cross. The catch: Lacks a bit of detail compared to the top ranked speakers in other size categories, dip at 5.5kHz.
The Teufel Rockster Cross is the lighter option. A splash resistant speaker with fairly neutral, vocal focused sound and punchy, controlled bass that suits rock and jazz. At 5.3 lbs (2.4 kg) it weighs much less than the Tribit Stormbox Blast at 12 lbs (5.45 kg). It supports aptX Bluetooth, which the Tribit Stormbox Blast lacks. The tradeoff: Outdoor mode can sound somewhat harsh due to the 4kHz peak.
Buy the Tribit Stormbox Blast at $199.99 if you want a boombox speaker. Buy the Teufel Rockster Cross at $199.99 if you want a large speaker instead.
