Needless to consider having low, a box with a cut of at least 100 Hz is required.
Otherwise, the sound is excellent with very present mids and treble quality off a lot of emotion through music listening. The sound is at rare moments a little metal, but it is negligible.
The appearance is correct: it is plastic, but the quality of plastic. Well, that did not still the Monitor class III for example ...
The supplied wall mount exudes quality.
All good. I recommend, especially at this price!
Beware of references "One Pro Control" or "Control 1Xtreme" swarming. They are also well JBL but often old versions often with a lower sensitivity.
