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.

Tribit Stormbox Blast 2: $299.99 Amazon eBay

Tribit Stormbox Blast 2 ranking card

Older model: the Tribit Stormbox Blast (ranked higher, rated 4.5/5).

Pros: Pretty deep bass. Measured bass extension of 40Hz (-10dB).

Cons: Sounds quite muddy with the boosted lower and upper bass. Boosted treble around 6kHz. Xbass mode makes it sound even more muddy. Nowhere near as neutral and balanced as the first Blast and a big downgrade unless you only care about max volume
