Short answer: the JBL Authentics 300 if sound quality matters most, the W-King T11 if price matters most. The JBL Authentics 300 ranks #44 of 98 boombox speakers, rated 3.5/5, at $499.95. The W-King T11 ranks #53, rated 3.3/5, at $116.57, $383.38 cheaper.
The case for the JBL Authentics 300: Integrates both Amazon Alexa and Google Assistant simultaneously (rare for smart speakers). It links with other speakers (Wi-Fi Multi-Room), which the W-King T11 cannot. The catch: Narrow sounding, bass not as deep as others.
The W-King T11 is the louder, tougher option. A capable, weather-resistant party speaker with dual 5.25-inch woofers, a measured -10dB bass point around 43Hz, 112dB maximum output, mic/karaoke input, USB/microSD playback, TWS pairing and low-latency aux. Alan Ross Reviews measured it at 112dB at full volume, against 100dB for the JBL Authentics 300. It is rated IPX6, while the JBL Authentics 300 has no water resistance. It keeps a wired aux input, which the JBL Authentics 300 lacks. The catch: The tuning can sound hollow through the mids, so deep bass does not always translate to natural vocals or instruments.
Buy the JBL Authentics 300 if sound quality is the priority over the price, or the W-King T11 if the price is the priority over sound quality.

W-King T11: $116.57 Amazon $169.99 AliExpress $116.57 Lowest eBay
Pros: A capable, weather-resistant party speaker with dual 5.25-inch woofers, a measured -10dB bass point around 43Hz, 112dB maximum output, mic/karaoke input, USB/microSD playback, TWS pairing and low-latency aux. Its deep bass and 5.1kg size make it a strong option when punch and portability matter more than audiophile refinement. Measured bass extension of 43Hz (-10dB).
Cons: The tuning can sound hollow through the mids, so deep bass does not always translate to natural vocals or instruments. There is no app-based fine EQ, battery life is only a claimed 10 hours, and the external power brick is less convenient than USB-C charging.
