One speaker depends wired on the other, about 3 *

One speaker depends wired on the other. But I wanted for my personal needs 2 have single wireless speaker. This has a radio receiver and a Si'gnal for the other speaker then passes over a speaker cable was for me not apparent why 3 stars. To the sound I can not say that I have not tried. From a processing perspective, the boxing made a solid impression (5 Stars), but that did not help me. One box is active, but there is an external power supply which was also apparently glued watertight. The Neetzteil was quite large, about 7cm x 5cm x 18cm, 1x 230, 1x extra low voltage
