Short answer: the Turtlebox Grande for better sound quality, the Monster Rockin’ Roller 270 for the lower price, though neither ranks well in its class. The Turtlebox Grande ranks #81 of 113 boombox speakers, rated 2.6/5, at $730. The Monster Rockin’ Roller 270 ranks #104, rated 2.1/5, at $208.99, $521.01 cheaper. Both are rated below 3.0/5 among the 113 boombox speakers; for better sound, the Tribit Stormbox Blast ranks #2 at $199.99.
The Turtlebox Grande is the better-sounding, lighter option. A rugged, submersible, crush-proof speaker with a 10 inch woofer and a battery that lasts for days. At 18.8 lbs (8.53 kg) it weighs noticeably less than the Monster Rockin’ Roller 270 at 28.7 lbs (13 kg). It is rated IP67 against IPX4 for the Monster Rockin’ Roller 270. It links with other speakers (Turtlebox Party Mode), which the Monster Rockin’ Roller 270 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 Monster Rockin’ Roller 270 is the longer-running choice. A wheeled party speaker with an enormous battery, sound spread wide around it and a wireless phone charging pad. It is rated for 100 hours of battery against 25 for the Turtlebox Grande. It has an adjustable EQ, which the Turtlebox Grande lacks. The tradeoff: Bass not as deep as competitors, less neutral than ION speakers.
Buy the Turtlebox Grande if sound quality is the priority over the price, or the Monster Rockin’ Roller 270 if the price is the priority over sound quality.
