Short answer: the W-King D8. It ranks #61 of 120 large speakers by sound quality, rated 3.5/5, at $69.98; the DOSS Extreme Boom ranks #115, rated 2.1/5, and costs $75.99, so there is little reason to consider the other one.
The W-King D8 is the better-sounding, deeper-bass choice. An affordable stereo boombox with four drivers, waterproofing, and a long battery for backyard and beach playlists. Its bass reaches about 49Hz before falling 10dB, against 65Hz for the DOSS Extreme Boom.
The case for the DOSS Extreme Boom: An affordable waterproof outdoor speaker with a long rated battery, power bank output, and bass heavy sound for casual parties. The tradeoff: The measured 65Hz -10dB bass point means it lacks true low bass despite its boomy voicing.
Buy the W-King D8. It is rated higher for sound quality than the DOSS Extreme Boom and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
