Short answer: the Tribit Stormbox Lava. It ranks #3 of 120 large speakers by sound quality (rated 4.6/5); the Teufel Rockster Cross 2 ranks #22 (rated 4.2/5).
The Stormbox Lava plays louder and deeper. It measured about 108dB with bass to about 44Hz. The Cross 2 measured about 101dB with EQ, and the original Cross, which it sounds nearly identical to, reaches about 51Hz.
The Lava needs a light touch on EQ. Its XBass mode can make the low end muddy, and its front-facing design has a narrow soundstage. Its 10-band app EQ is far more detailed than the Cross 2’s bass and treble controls.
The Cross 2 wins on battery, claiming 38 hours against 24, and adds multipoint pairing and a USB-C sound card. Both have an aux input and a power bank.
Weather: IP67 on the Lava against IPX5 on the Cross 2. They weigh about the same.
Buy the Tribit Stormbox Lava. It is rated higher for sound quality than the Teufel Rockster Cross 2.
