Short answer: the JBL Xtreme 4 on measured sound quality, the W-King D8 on price. The JBL Xtreme 4 ranks #37 of 77 large speakers at $380. The W-King D8 ranks #43 at $79.98, $300.02 cheaper.
What the JBL Xtreme 4 offers: Removable battery. Slightly deeper bass than Xtreme 3. Use this EQ for the best sound quality. Watch for: High priced. Some bass boost. Dip in the upper bass to midrange makes it sound strange which cannot be EQd out. Some upper mids and treble boost at high levels.
What the W-King D8 offers: Decent sounding. Watch for: Slightly recessed mids. Distorted at high volumes.
Buy the JBL Xtreme 4 when sound quality outweighs the price for you, and the W-King D8 when the price outweighs sound quality instead.
