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 D8 ranks #58, rated 3.5/5, at $79.99, $120 cheaper, which does not close the gap in sound quality.
The Teufel Rockster Cross is the better-sounding choice. A splash resistant speaker with fairly neutral, vocal focused sound and punchy, controlled bass that suits rock and jazz. It supports aptX Bluetooth, which the W-King D8 lacks. Watch for: Outdoor mode can sound somewhat harsh due to the 4kHz peak.
The W-King D8 is the longer-running, tougher pick. An affordable stereo boombox with four drivers, waterproofing, and a long battery for backyard and beach playlists. It is rated for 24 hours of battery against 16 for the Teufel Rockster Cross. It is rated IPX7 against IPX5 for the Teufel Rockster Cross.
Buy the Teufel Rockster Cross. It is rated higher for sound quality, and saving $120 with the W-King D8 does not make up for the sound-quality gap.
