These are not really the same size class, and that is the honest framing here. The Tribit Stormbox Blast ranks #2 of 113 boombox speakers by sound quality at $199.99; the Marshall Stockwell II ranks #11 of 120 large speakers by sound quality at $229.99.
The Tribit Stormbox Blast is the louder, longer-running option. A boombox with bass and volume that rival bigger party speakers, quite neutral sound, and a 30 hour battery. Alan Ross Reviews measured it at 108dB at full volume, against 96dB for the Marshall Stockwell II. It is rated for 30 hours of battery against 20 for the Marshall Stockwell II. It is rated IPX7 against IPX4 for the Marshall Stockwell II. Watch for: Lacks a bit of detail compared to the top ranked speakers in other size categories, dip at 5.5kHz.
The Marshall Stockwell II is the lighter pick. A light, strap equipped speaker with some of the most natural sound around, even off to the side, and a long battery. At 3.1 lbs (1.4 kg) it weighs much less than the Tribit Stormbox Blast at 12 lbs (5.45 kg). The tradeoff: Not very loud, and the added DSP reverb may annoy purists.
Buy the Tribit Stormbox Blast at $199.99 if you want a boombox speaker. Buy the Marshall Stockwell II at $229.99 if you want a large speaker instead.
