These are not really the same size class, and that is the honest framing here. The Teufel Rockster Cross ranks #23 of 82 large speakers by sound quality at $199.99; the Soundcore Boom 2 Plus ranks #29 of 76 boombox speakers by sound quality at $179.99.
Why pick the Teufel Rockster Cross: Pretty neutral frequency response. The tradeoff: Outdoor mode can sound somewhat harsh due to the 4kHz peak.
Why pick the Soundcore Boom 2 Plus: Quite a bit lighter than most of the other boombox size speakers. 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 $179.99 for a boombox speaker instead.

The Two Speakers In Full
Teufel Rockster Cross: $199.99 Amazon eBay
Newer model: the Teufel Rockster Cross 2, rated 4.2/5.
Pros: Pretty neutral frequency response. More vocal/midrange-focused than the JBL Xtreme 4, thanks to a larger mid/bass driver - better suited to rock and jazz. Nicer upper-bass detail than the JBL Xtreme 4. Punchy, well-controlled bass that suits rock music, unlike the Soundcore Boom 2 Plus’s overboosted, uncontrolled bass even at stock tuning. Clear, detailed audio with good vocal presence and solid Bluetooth codec support even a couple years after release. Measured bass extension of 51Hz (-10dB).
Cons: Outdoor mode can sound somewhat harsh due to the 4kHz peak. Not as deep or full-sounding in the bass as the JBL Xtreme 4.

Soundcore Boom 2 Plus: $179.99 Amazon B&H Photo Video eBay
Older model: the Soundcore Motion Boom+ (rated 2.9/5).
Pros: Quite a bit lighter than most of the other boombox size speakers. This speaker will likely move up as we get a good EQ tune that makes it a lot more neutral. Measured bass extension of 39Hz (-10dB).
Cons: Warm tuning meaning a rolled off treble and some upper bass boost. Reasonably deep bass, but not as good as the top ranked.
