Short answer: the Zealot ZE41. It ranks #17 of 89 boombox speakers by sound quality, rated 4.1/5, at $259.90. The Pioneer PBM5 ranks #89, rated 2.0/5, at $149, $110.90 cheaper, which does not close the gap in sound quality.
What the Zealot ZE41 does well: The absolute best value for the bass performance, play time and max volume in the boombox class. The tradeoff: The heaviest and biggest boombox speaker around.
What the Pioneer PBM5 does well: 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. Watch for: 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 Zealot ZE41. It is rated higher for sound quality, and saving $110.90 with the Pioneer PBM5 does not make up for the sound-quality gap.

The Two Speakers In Full
Zealot ZE41: $259.90 Amazon AliExpress eBay
Pros: The absolute best value for the bass performance, play time and max volume in the boombox class.
Cons: The heaviest and biggest boombox speaker around. A little rolled off up top and not that balanced through the rest of the range. Clarity isn’t as good as better speakers. Bass EQ is bloated and muddy sounding.

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.
