Have these and 30 more favorable model of Edifier (Edifier RT1600 Plus 2.0) angetestet. In a direct comparison I noticed that generate R1900 TII significantly more defined bass. Favor right away me! Can I really recommend. However, a point of criticism: Unfortunately, the boxes without cover look relatively stupid. And they are a bit too big for desktop use (ie computer speakers). In terms of size, the RT1600 were yet more comfortable and are also saw chicker without cover. I opt for the R1900 TII because me the image Kling very responsive - looks balanced and the bass is pretty good for 2.0er boxes.
