#14 Harman Kardon Onyx Studio 7: $248.90 Amazon eBay

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.

Related speakers: Harman Kardon Onyx Studio 4, Harman Kardon Onyx Studio 5, Harman Kardon Onyx Studio 6, Harman Kardon Onyx Studio 8, Harman Kardon Onyx Studio 9.

How it compares: Just above it: Harman Kardon Onyx Studio 6 - $119 cheaper. Just below it: Harman Kardon Onyx Studio 9 - $59 cheaper.
