Unbelievable what was for a sound comes out! In December 2013. I bought speaker of the brand Canton for my newly furnished 5.1 system, a couple Rear. That reminds me of the sound had not fallen, I swapped it for the next day and decided to go for the Harman Kardon HK S4. These are about the same size and similar performance. However, the sound they are worlds apart. I did not think that there are such differences in comparable loudspeakers. For testing, I have my two front speakers replaced by this Harman Kardon HK S4 and was there absolutely loved it. In connection with a separate active subwoofer, this speaker would even ideally suited as stereo front speakers. The speaker terminals are located on the bottom case. The speaker cables are connected via clamp connector to the speakers. The included wall mount also makes a decent and stable impression. The anchors supplied I have been replaced by more stable Hilti anchors. I am fully satisfied with the rear speakers and they may hesitate to recommend! Real horny boxes!
