Short answer: the Stormbox Blast, and it’s the cheaper one. It ranks #2 of 113 boombox speakers at $199.99; the X20 ranks #43 at $229.99.
The X20 leans on raw specs: a 7.5-inch subwoofer, 330W peak power, and a 24-hour battery with a built-in power bank. Its own cons note a rising frequency response with rolled-off upper treble and peaks at 700Hz and 1.2kHz.
The Blast wins on the tuning that actually matters for sound. Bass almost as deep as a JBL Partybox 100, a neutral default and xbass mode, and a reviewer EQ that became the factory default in firmware 3.5.
Buy the Stormbox Blast. It’s both cheaper and dramatically better measured.
Still deciding? The full Portable Bluetooth rankings cover every ranked option.
A boombox with bass and volume that rival bigger party speakers, quite neutral sound, and a 30 hour battery.
A loud stereo party speaker with a large subwoofer, a 24 hour battery with power bank, and water resistance.
