Short answer: the W-King X20 for the higher ranking, the Gemini GRV-650L for the lower price. The W-King X20 ranks #28 of 70 boombox speakers at $249.99. The Gemini GRV-650L ranks #35 at $149.95, $100.04 cheaper.
The case for the Gemini GRV-650L: Pretty amazing value for the money. Set against that: Not quite as deep bass as the top ranked speakers.
What the W-King X20 gets right: 200W RMS output with 330W peak power, 112dB max volume, exceptional 24-hour battery life with power bank, IPX6 waterproof. The catch: Rising frequency response but upper treble rolled off, 700hz and 1.2khz peaks.
