Tip 1 (for installation): Installation on a shelf gives the sound an even more rounded and better sound. Of course, the speaker needs to back a few centimeters of air, so do not put directly in front of books. Is actually clear: The bass comes back out and if this is then reflected forward toward the audience will make the sound.
Tip 2 (for classical music listeners): If for you is a bit exhausting longer classical listening to the speaker and you use the Bluetooth transmission: I have the impression that I can listen to classical music with less fatigue when I and the player via jack cable AUX-in jack Connect the speakers. I suspect that has something to do with apt-X, but I am not busy.
Tip 3 (for Android owners): If it bothers you too, having to worry about getting off the Android device various alarms (notifications, reminders, alarm clock ...) having to disable to hear so smoothly, I recommend the App "Do not break!" to get from Trent Pierce on Google Play, as free version or as a pay app for 1.04 EUR (I have not regretted the purchase).
