Short answer: the Teufel Rockster Cross for better sound quality, the W-King T9 for the lower price. The Teufel Rockster Cross ranks #21 of 78 large speakers at $199.99. The W-King T9 ranks #38 at $130, $69.99 cheaper.
What the W-King T9 offers: 80W output power, 106dB max volume, 24-hour battery life, power bank function, Bluetooth 5.3 with 100ft range, TWS stereo pairing with wireless microphone, dual subwoofers, RGB lighting, MicroSD and AUX support, USB-C charging, karaoke capability Watch for: Peaks in the upper mids which makes it sound a bit harsh.
What the Teufel Rockster Cross offers: 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. Watch for: 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.
Buy the W-King T9 when the price outweighs sound quality for you, and the Teufel Rockster Cross when sound quality outweighs the price instead.
Battery life favors the W-King T9: rated for 24 hours against 16 hours for the Teufel Rockster Cross.
If water resistance matters to you, the Teufel Rockster Cross at IPX5 (water jets) holds up far better than the W-King T9 at no water resistance.
