Short answer: the Teufel Rockster Cross. It ranks #23 of 115 large speakers by sound quality, rated 4.2/5, at $199.99. The W-King T9 ranks #50, rated 3.6/5, at $111.23, $88.76 cheaper, not enough of a saving to outweigh the sound-quality gap.
The W-King T9 is the longer-running pick. A loud stereo party speaker with a wireless microphone for karaoke, lights, a long battery and a power bank. It is rated for 24 hours of battery against 16 for the Teufel Rockster Cross. Watch for: Peaks in the upper mids which makes it sound a bit harsh.
The Teufel Rockster Cross is the better-sounding, 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 much less than the W-King T9 at 10.1 lbs (4.6 kg). It is rated IPX5, while the W-King T9 has no water resistance. It supports aptX Bluetooth, which the W-King T9 lacks. The catch: Outdoor mode can sound somewhat harsh due to the 4kHz peak.
Buy the Teufel Rockster Cross. It is rated higher for sound quality, and the $88.76 saving on the W-King T9 is not enough to make up the difference.
