Got the reviews read before buying and not expecting much. All the more pleased I was when the first music came out of the speakers. For the size and the price, the speakers sound really good! The volume is sufficient for a normal sized room comfortable to sonication. The sound suggests the Mini Speakers my MacBook Pros naturally to classes. Again, there are no high-end speakers, but for the price and the size they sound really good pop music anyway but also classical music comes with swabs to casually listening. Installation: Depp just is mounted just below the Dell monitors. Power is supplied by the monitor, but there is an extra plug behind the Dell monitor. My Dell monitor has audio outputs for 5.1 desktop speaker. The output for the front speakers the audio cable to the monitor via Soundbar.Dann DisplayPort cable was connected to the MacBook Pro and the selected source to monitor. Thus, you need only one cable for audio and picture from the computer to the monitor. Very convenient, thereby one also has less clutter. :-) However, I can no longer affect the volume of the keyboard, but only on the knob on the Soundbar. For me, but bearable. From me a strong buy recommendation (although I use the speaker only 2 days), if you have little space on the desk and a big Dell monitor has since then come sound and picture from one direction.
