Short answer: the Gemini GGO-650L, though neither ranks well in its class. It ranks #61 of 76 boombox speakers by sound quality, rated 2.5/5, at $99.95; the Marshall Tufton ranks #63, rated 2.4/5, and costs $378.99, so there is not much of a tradeoff to weigh. Both are rated below 3.0/5 among the 76 boombox speakers; for better sound, the Tribit Stormbox Blast ranks #2 at $179.99.
Why pick the Gemini GGO-650L: At 4.2 kg, Gemini GGO-650L combines 6.5” woofer + tweeter with Bluetooth and aux. Watch for: Bass is limited by its ~56Hz specification.
The case for the Marshall Tufton: 20 hour battery life; 2.5 hour full charge, or 20-min quick-charge for 4 hours of play. Watch for: Not much lower bass, upper bass boomy, boosted treble, not very balanced overall.
Buy the Gemini GGO-650L. It is rated higher for sound quality than the Marshall Tufton and costs less, which makes it the one to get unless you need something the other one does better.
Battery life favors the Marshall Tufton: rated for 20 hours against 10 hours for the Gemini GGO-650L.
Water resistance is not close: the Gemini GGO-650L is rated at IPX5 (water jets), well ahead of the Marshall Tufton at IPX2 (light drips).
