Short answer: the Turtlebox Grande on measured sound quality, the ION Pathfinder 320 on price, though neither ranks well in its class. The Turtlebox Grande ranks #81 of 113 boombox speakers, rated 2.6/5, at $730. The ION Pathfinder 320 ranks #100, rated 2.2/5, at $129.99, $600.01 cheaper. Both are rated below 3.0/5 among the 113 boombox speakers, and the Tribit Stormbox Blast, ranked #2 at $199.99, is a better place to start if sound quality matters.
The Turtlebox Grande is the better-sounding, tougher pick. A rugged, submersible, crush-proof speaker with a 10 inch woofer and a battery that lasts for days. It is rated IP67 against IPX5 for the ION Pathfinder 320. It links with other speakers (Turtlebox Party Mode), which the ION Pathfinder 320 cannot. It plays in stereo from a single unit, unlike the ION Pathfinder 320. 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 ION Pathfinder 320 is the longer-running option. A wheeled party speaker with an enormous battery, splash resistance, FM radio and ports for charging phones. 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 is not as deep as competitors.
Buy the Turtlebox Grande if sound quality is the priority over the price, or the ION Pathfinder 320 if the price is the priority over sound quality.
