The quality is also good in advance. Made entirely of metal. Heavy and larger than expected, the speakers come well packaged with instructions and wall mount. This is easy to install and the speakers are rotating / tilting. The cable connectors are very high quality, well characterized metal. There are no screw terminal connections and, probably due to the limited space.
The sound is stunningly good for the size. The little ones have to be made sure to "Small" in the receiver but. There are of course only effect speakers but that they do really well.
For testing purposes I have ever heard in stereo mode, and here they are, physically understandable, totally overwhelmed and have no depth. I can thus thoroughly recommend it as a pure effect speaker for the rear. They fit quite unobtrusively and harmoniously into the living room one, are good to hide.
Overall, far better than other plastic Brüllwürfel and for the price you can strike without hesitation. However, not as front speakers because they really have no depth and space wealth.
