Excellent speaker

I have good ears for music. As such, I look for a speaker system that is music to my ears. The Herman Kardon Onyx speaker is my choice. I previously owned the Onyx 4 that I have been very satisfied with. Confidently, I purchased the Onyx 9 knowing that the sound quality would be excellent. I was not disappointed. The realism of the music from Onyx 9 is impressive--- crisp and immersive, even at a low volume. Aesthetically, the Onyx 9 is solidly built. Its elegance adds to the decor of the room. The only feature I did not see in the Onyx 9 is the telephone capability which the Onyx 4 has. Nevertheless, I love the Onyx 9 (from the bottom of my heart), and would highly recommend it to others.
I would recommend this to a friend!

The prettiest BT-speaker (aesthetically)

I don't even have the speaker I just want to say that it's probably the most attractive Bluetooth speaker I've ever seen.
(The Only exception is the Sony X5.
You know what I'm talking about? The X5 was definitely a pioneer in the luxury Bluetooth speaker game it's only competition was the Bose soundlink mini, and even though the Bose was louder, the X5 definitely edged it out.
The sound quality was just world's better than the Bose.)
