Harman Kardon Onyx Studio Harman Kardon Onyx Studio can put out enough sound, particularly in the low end, to justify its size and price. You’ll notice a bit more focused on bass yet it gives less crisp high end than the adjustable-bass-and-treble, always-plugged-in Marshall Stanmore or the much more portable (but less powerful) Bose SoundLink.

At $199, the Harman Kardon Onyx Studio remains to be very appealing speaker.
