Short answer: the Tronsmart Bang Max. It ranks #52 of 112 boombox speakers by sound quality, rated 3.4/5, at $229.99; the Turtlebox Grande ranks #80, rated 2.6/5, and costs $730, so there is little reason to consider the other one.
The case for the Turtlebox Grande: A rugged, submersible, crush-proof speaker with a 10 inch woofer and a battery that lasts for days. It links with other speakers (Turtlebox Party Mode), which the Tronsmart Bang Max 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.
The Tronsmart Bang Max is the better-sounding, deeper-bass option. A loud, feature packed party speaker with big bass, app EQ, lights, and separate mic and guitar inputs. Its bass reaches about 39Hz before falling 10dB, against 55Hz for the Turtlebox Grande. At 12.8 lbs (5.8 kg) it weighs noticeably less than the Turtlebox Grande at 18.8 lbs (8.53 kg). It has an adjustable EQ, which the Turtlebox Grande lacks. Watch for: Its bass-first tuning prioritizes impact over accuracy: upper mids and lower treble can sound unnatural, while fine midrange and treble detail are limited.
Buy the Tronsmart Bang Max. 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.
