Short answer: the Gemini GRV-650L for value, the W-King X20 for output and battery life. The Gemini is pretty amazing value for the money, though its bass is not quite as deep as the top ranked speakers. The X20 brings 200W RMS with 330W peak, 112dB max volume, a 24-hour battery with power bank and IPX6 waterproofing, at the cost of a rising response with rolled off upper treble and peaks at 700Hz and 1.2kHz.
Buy the W-King X20. It is rated higher for sound quality, and the $80.04 you would save on the Gemini GRV-650L does not close the gap.
