With only 15 kg super mobile, robust and very leistungsstark.Ich take them with me to the neighborhood party outside, or for party, or the like. You have additional taxes a bit with the sound settings and be careful that the midrange and tweeter horns do not sound too aggressive. This can be uncomfortable. But with the super efficiency, you can then loosely outside sound for a garden party. Consider, for the money! I have the boxing several years (not Amazon) and precisely for the stated purpose, the boxes are ideal. For everyday music enjoyment I have of course other boxes in the house, but I also do not want to compromise with a party. In these, however: nail stuck in the wall, box it and off you go! Would I buy again immediately.
