Tribit Stormbox Blast vs Harman Kardon Onyx Studio 7

The Blast is an amazing speaker for its size that competes with some Party class models with bass almost as deep as a Partybox 100, though it lacks a bit of detail against top ranked speakers and dips at 5.5kHz.

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.

Harman Kardon Onyx Studio 7: $248.90 Amazon eBay

Harman Kardon Onyx Studio 7 ranking card

Newer model: the Harman Kardon Onyx Studio 9, ranked lower, rated 4.1/5.

Pros: The addition of dual tweeters gives the Studio 7 a wider, more spacious presentation than older Onyx models. It delivers strong, deep bass, useful large-room volume and can pair with a second Studio 7 for stereo. Measured bass extension of 37Hz (-10dB).

Cons: Consumer Reports finds the bass prominent and boomy, mids hazy, treble slightly smeared and the soundstage congested. Battery life remains only about eight hours, it has no water rating or advanced codecs, and it is not an especially loud outdoor speaker.
