Tribit Stormbox Blast ranking card

Newer model: the Tribit Stormbox Blast 2, ranked lower, rated 3.8/5.

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.
