Short answer: the Harman Kardon Luna for better sound quality, the W-King D320 for the lower price. The Harman Kardon Luna ranks #22 of 136 medium speakers at $290.99. The W-King D320 ranks #44 at $69.99, $221 cheaper.
What the Harman Kardon Luna offers: Pretty balanced sound besides the boosted bass. Watch for: Not stereo. Boosted bass, not as detailed as higher ranked speakers
What the W-King D320 offers: 40W output power, IP67 waterproof, 24-hour battery life, customizable EQ app with 6 preset modes, Bluetooth 5.3, AUX and MicroSD support, dual tweeters with passive radiators, USB-C charging Watch for: Not stereo. Warm tuning. Lacking some detail. Rolled off treble
Buy the Harman Kardon Luna when sound quality outweighs the price for you, and the W-King D320 when the price outweighs sound quality instead.
There is a real battery-life gap here: the W-King D320 is rated for 24 hours, the Harman Kardon Luna only 12 hours.
