Short answer: the Bose SoundLink Max. It ranks #17 of 120 large speakers by sound quality (rated 4.3/5); the Teufel Rockster Cross 2 ranks #22 (rated 4.2/5).
The SoundLink Max has deep, rich bass, reaching about 48Hz with fairly neutral tuning, but it has a big upper bass peak, a dipped midrange and distorts above about 80% volume. The Cross 2 sounds almost identical to the original Cross, which is fairly neutral and vocal focused with punchy bass, and its app EQ adds bass punch.
Battery: Bose claims 20 hours and real world testing found over 40. Teufel claims 38 hours, or 46 in Eco Mode.
Toughness: the Max is IP67 against the Cross 2’s IPX5. Both have an aux input and a USB-C power bank. The Max weighs 4.9 lbs (2.2 kg), the Cross 2 5.3 lbs (2.4 kg).
Connectivity: the Cross 2 adds AAC, multipoint and a USB-C sound card. The Max is SBC only.
