Short answer: the W-King D8 is decent, and the Kilburn II’s flaws are worse documented. The D8 sounds decent, though its mids are slightly recessed and it distorts at high volumes. The Kilburn II adds a 20W Class D amp, dual 8W tweeters and 20+ hours of battery, but has boosted upper bass, limited detail, shallower bass, an upper mids peak, IPX2 water resistance and AC charging.
Buy the Marshall Kilburn II if sound quality matters more than the price. Buy the W-King D8 if the price matters more than sound quality.
Water resistance is not close: the W-King D8 is rated at IPX7 (brief submersion), well ahead of the Marshall Kilburn II at IPX2 (light drips).
