Short answer: the JBL Xtreme 5. It ranks #2 of 120 large speakers by sound quality (rated 4.6/5); the Teufel Rockster Cross 2 ranks #22 (rated 4.2/5).
The Xtreme 5 goes deeper and louder. It reaches well below 40Hz with excellent off-axis dispersion and measured about 110dB. The Rockster Cross 2 uses the same drivers as the original Cross, which reaches about 51Hz, and it measured about 101dB with EQ.
The Cross 2 lasts longer and keeps an aux input. It claims 38 hours, or 46 in Eco Mode, against 28 for the Xtreme 5, and has a 3.5mm aux input and a USB-C sound card. The Xtreme 5 has no aux input. The Cross 2 is also lighter, at 5.3 lbs (2.4 kg) against 6.4 lbs (2.9 kg).
Toughness favors the JBL. The Xtreme 5 is IP68 and has a removable battery. The Cross 2 is only IPX5, which covers water jets but not submersion.
Tuning: the Xtreme 5 needs its custom EQ to sound its best, and has a hole in the upper bass that EQ cannot fix. The Cross 2’s app EQ adds noticeable bass punch, but its bass and treble controls are limited.
Buy the JBL Xtreme 5. It is rated higher for sound quality than the Teufel Rockster Cross 2.
