Negative falls directly on the processing. In a loudspeaker the reflex tube was loose so I could still be alive. Happened already times during transport. But spots on the beads of the speaker suggest improper storage. The processing of the "spikes" is wrong.
Now the sound. Unfortunately succeed the speakers not to excel in a discipline. Neither heights are still deep reflect satisfactorily.
Despite various settings on the AV receiver, the bass is too thin, and at higher tones the sound consumed unfortunately very.
My conclusion. Neither to use for home theater nor music.
