Short answer: the Diamondboxx M3 for better sound quality, the Bumpboxx Flare 6 for the lower price. The Diamondboxx M3 ranks #53 of 75 boombox speakers at $700. The Bumpboxx Flare 6 ranks #58 at $300, $400 cheaper.
What the Diamondboxx M3 offers: An unusually compact 5kg high-output boombox, with a claimed 200W RMS Class A/B amplifier, 114dB maximum level, active crossovers and a choice of large battery packs. It has aux input, USB-C power and TWS pairing, while the aluminum heat sink is designed to sustain loud playback without thermal shutdown. Watch for: Despite its output, bass does not reach as deep as the best large portables and can distort when pushed hard. The treble-forward tuning can sound aggressive, there is no app or EQ to correct it, and the lack of a water rating makes it a poor match for poolside or rough-weather use.
What the Bumpboxx Flare 6 offers: At 5.9 kg, Bumpboxx Flare 6 combines 6” woofer + tweeters with Bluetooth. Claimed 12 hours (manufacturer specified) battery life, ipx6 protection, up to 115db and stereo playback make its feature set practical for its intended room or portable use. Watch for: There is no companion app. No EQ adjustment.
Buy the Diamondboxx M3 when sound quality outweighs the price for you, and the Bumpboxx Flare 6 when the price outweighs sound quality instead.
If sound quality matters at all to you, skip the Bumpboxx Flare 6. It ranks near the bottom of the 75 boombox speakers, so look higher up the list instead.
Battery life favors the Diamondboxx M3: rated for 40 hours against 12 hours for the Bumpboxx Flare 6.
Water resistance is not close: the Bumpboxx Flare 6 is rated at IPX6 (powerful water jets), well ahead of the Diamondboxx M3 at no water resistance.
