Short answer: the W-King T11. Both are rated 3.3/5 for sound quality (#55 and #56 of 113 boombox speakers), and the W-King T11 costs $116.57 against $149.95 for the Gemini GRV-650L, and with sound quality even, the cheaper one is the better buy.
The W-King T11 is the lighter pick. A weather resistant party speaker with deep bass, high volume and a karaoke mic input. At 11.2 lbs (5.1 kg) it weighs noticeably less than the Gemini GRV-650L at 15.7 lbs (7.1 kg). It has an adjustable EQ, which the Gemini GRV-650L lacks. Watch for: The tuning can sound hollow through the mids, so deep bass does not always translate to natural vocals or instruments.
Why pick the Gemini GRV-650L: A great value party speaker with an included wireless mic, remote, FM radio and water resistance. The tradeoff: Not quite as deep bass as the top ranked speakers.
Buy the W-King T11. Both are rated the same for sound quality, and it costs $33.38 less than the Gemini GRV-650L.
