Short answer: the Turtlebox Grande if sound quality matters most, the Pioneer PBM5 if price matters most, though neither ranks well in its class. The Turtlebox Grande ranks #69 of 89 boombox speakers, rated 2.6/5, at $730. The Pioneer PBM5 ranks #89, rated 2.0/5, at $149, $581 cheaper. Both are rated below 3.0/5 among the 89 boombox speakers, and the Tribit Stormbox Blast, ranked #2 at $179.99, is a better place to start if sound quality matters.
What the Turtlebox Grande does well: 10-inch woofer. The tradeoff: In YouTube sound samples it sounds only okay, and bass is shallow for a 10 inch woofer, only down 10dB at about 55Hz.
Why pick the Pioneer PBM5: Loud for its size: Williston Audio Labs measured about 105 dB at 2 meters, louder than the Turtlebox Original Gen3 and Kicker Bullfrog BF400 in the same test. The catch: Williston Audio Labs was not impressed with its sound: there is very little bass below 100Hz, and the amplifier’s output has a big dip from 1.6kHz to 10kHz that leaves the upper mids and treble recessed.
Buy the Turtlebox Grande if sound quality matters more than the price. Buy the Pioneer PBM5 if the price matters more than sound quality.
There is a real battery-life gap here: the Turtlebox Grande is rated for 25 hours, the Pioneer PBM5 only 13 hours.

The Two Speakers In Full
Turtlebox Grande: $730.00 Amazon eBay
Pros: 10-inch woofer. IP67 submersible shell with crush-proof ABS exterior. 158Wh battery provides ~3 days of playback. Bluetooth 5.4, party mode (100+ speakers). Measured bass extension of ~55Hz (-10dB).
Cons: In YouTube sound samples it sounds only okay, and bass is shallow for a 10 inch woofer, only down 10dB at about 55Hz. It is rated at just 86W, and like the smaller Turtleboxes it won’t reach its claimed 126dB at a standard one meter distance. Expensive for what it delivers. It charges only from its own barrel plug adapter, not USB-C.

Pioneer PBM5: $149.00 Sam’s Club eBay
Pros: Loud for its size: Williston Audio Labs measured about 105 dB at 2 meters, louder than the Turtlebox Original Gen3 and Kicker Bullfrog BF400 in the same test. Two 5.25 inch woofers and two 2 inch tweeters with a port tuned to 48Hz, two microphone inputs plus a guitar input with bass, treble and reverb controls for the mics, aux and USB playback, IPX5 splash resistance, RGB lights, a shoulder strap, Bluetooth 5.4 with Auracast, and charging from either USB-C or the included AC cord. A rated 13 hours at 60% volume.
Cons: Williston Audio Labs was not impressed with its sound: there is very little bass below 100Hz, and the amplifier’s output has a big dip from 1.6kHz to 10kHz that leaves the upper mids and treble recessed. None of the EQ presets fixed it, and a 1990 JVC boombox sounded cleaner. The amp measured about 90W in total, not the claimed 300W, and only about 23W per woofer channel on battery. USB playback is MP3 only, there is no audio output and no microphone in the box, and it is sold only at Sam’s Club.
