The Edifier is very well made. The subwoofer bawls intense, but not too vigorously or even unpleasant strong as it makes the Creative Gigaworks T3.
The satellites are also very high quality, no plastic but a nice MDF wood. The high and middle tones are very well reproduced.
Actually there is in terms of sound quality no complaints, except maybe the size of the satellite or the amplifier forgets the settings.
This also influences the overall rating of 4 stars only then. Clear, one could argue, only a matter of few seconds is so set the whole again,
but over time it sucks a bit. I use my PC several times a day and adjust it at each start-up is a pain.
If that does not interfere with the Edifier C3 gets a real top product, clean tones, pleasant sounding subwoofer and great design to boot.
Nevertheless, I decided on the Logitech Z623, because my subjective impression is even better with this system. Even the bass of the subwoofer will be even better represented one tick.
Basically, one of their own taste if Edifier C3 or the Logitech Z623. For me personally, the Logitech Z623 is tonally a little bit better, consumes less space, more compact, but more plastic and less quality appearing.
I can only advise all these two systems to compare.
Have fun and good sounds everywhere :-)
