The Two Speakers In Full

Harman Kardon Go + Play 3: $385 Amazon Ebay Refurbished

Pros: Warm sound with boosted bass. Deepest bass out of any speaker in this size. Sound is more natural than the Go + Play2.

Cons: Just a little over half as loud as the higher rated boomboxes. Only 8 hours of battery at medium volume. No water rating.

Setup: Use the hidden EQ modes to adjust the bass up when outside and down when inside. To adjust bass, quickly press the bluetooth and volume down buttons together, the number of light flashes tell you what mode you’re in. To adjust treble, quickly press the volume up and phone buttons at the same time, the number of yellow flashes on the light tell you what mode you are in.

Tribit Stormbox Blast: $179.99 Amazon

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.

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.
