Sony ULT Field 7 vs Tribit Stormbox Blast

Last updated: September 21, 2026

Short answer: the Tribit Stormbox Blast, and it isn’t close. It ranks #2 of 75 boombox speakers against the ULT Field 7’s #42, at $220.01 less.

Sony ULT Field 7 vs Tribit Stormbox Blast

The Stormbox Blast’s notes are genuinely enthusiastic for its size. They call it an amazing speaker given its footprint, competing well with speakers in the larger party size class, with bass almost as deep as a JBL Partybox 100. It measures quite neutral in both default and xbass modes, and the reviewer points to community EQ profiles that Tribit has since folded into its own firmware defaults. Its real flaw is a lack of fine detail next to the top ranked speakers in other size categories, with a dip around 5.5kHz.

The ULT Field 7’s own notes are far more modest. They describe it as better sounding than Sony’s own XG500, but still not reaching the bass depth of the top ranked speakers in its class, with an 8kHz peak noted as a flaw. Its measured bass extension of about 52Hz trails the Stormbox Blast’s 43Hz.

What the ULT Field 7 does add: LDAC codec support alongside SBC and AAC, where the Stormbox Blast is SBC only, plus a slightly higher IP67 rating against the Blast’s IPX7.

Buy the Tribit Stormbox Blast for dramatically better measured sound at a fraction of the price.

Buy the Sony ULT Field 7 only if LDAC codec support for a compatible phone is a hard requirement for you.

Tribit Stormbox Blast: $179.99 Amazon eBay

Tribit Stormbox Blast ranking card

Pros: Amazing speaker given its size, competes well with some speakers in the Party size class, bass almost as deep as a Partybox 100. Quite neutral in the default and xbass modes, but try Oluv’s EQ or Alan Ross’s EQ for a slightly more neutral sound. Oluv has mentioned v3.5 now uses his EQ as the defaults and sounds extremely good. 2 different light modes or can be turned off. Measured bass extension of 43Hz (-10dB).

Cons: Lacks a bit of detail compared to the top ranked speakers in other size categories, dip at 5.5kHz. Without the above EQ this speaker would rank around #4 in the rankings. The curved underside of the handle makes it a little harder to grip and can be uncomfortable to carry long distances.
