Short answer: the W-King T11. It ranks #55 of 113 boombox speakers by sound quality, rated 3.3/5, at $116.57; the Turtlebox Grande ranks #81, rated 2.6/5, and costs $730, which makes this an easy call rather than a real tradeoff.
The W-King T11 is the better-sounding, deeper-bass choice. A weather resistant party speaker with deep bass, high volume and a karaoke mic input. Its bass reaches about 43Hz before falling 10dB, against 55Hz for the Turtlebox Grande. At 11.2 lbs (5.1 kg) it weighs much less than the Turtlebox Grande at 18.8 lbs (8.53 kg). It has an adjustable EQ, which the Turtlebox Grande lacks. Watch for: The tuning can sound hollow through the mids, so deep bass does not always translate to natural vocals or instruments.
The Turtlebox Grande is the longer-running choice. A rugged, submersible, crush-proof speaker with a 10 inch woofer and a battery that lasts for days. It is rated for 25 hours of battery against 10 for the W-King T11. It links with other speakers (Turtlebox Party Mode), which the W-King T11 cannot. The catch: In YouTube sound samples it sounds only okay, and bass is shallow for a 10 inch woofer, only down 10dB at about 55Hz.
Buy the W-King T11. It is rated higher for sound quality than the Turtlebox Grande and costs less, which makes it the one to get unless you need something the other one does better.
