These are not really the same size class, and that is the honest framing here. The Teufel Rockster Cross ranks #23 of 120 large speakers by sound quality at $199.99; the Soundcore Boom 2 Plus ranks #39 of 113 boombox speakers by sound quality at $169.99.
The Teufel Rockster Cross is the lighter pick. 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 noticeably less than the Soundcore Boom 2 Plus at 8.4 lbs (3.8 kg). It supports aptX Bluetooth, which the Soundcore Boom 2 Plus lacks. The catch: Outdoor mode can sound somewhat harsh due to the 4kHz peak.
The Soundcore Boom 2 Plus is the deeper-bass, tougher pick. A fairly light stereo boombox, easy to carry to the beach or park. Its bass reaches about 39Hz before falling 10dB, against 51Hz for the Teufel Rockster Cross. It is rated IPX7 against IPX5 for the Teufel Rockster Cross. It links with other speakers (PartyCast 2.0), which the Teufel Rockster Cross cannot. Watch for: Warm tuning meaning a rolled off treble and some upper bass boost.
Buy the Teufel Rockster Cross at $199.99 for a large speaker, or the Soundcore Boom 2 Plus at $169.99 for a boombox speaker instead.
