I have taken these boxes without great expectations in receiving, delivery was quite fast, I wanted to mention well opened the right demolished packaging back to business see as some parts are loose in box I've first thought nothing appraised externally boxes and really very poor processing ok so I but can live as long as the sound is good so infected and nothing ... I've then considered what the problem is the cable Geckheckt etc nothing found .. now that the grid on the box anyway almost loose was screwed off I thought I just look inside and see because the magnet of the box is loose on the ground Canceled probably by transporting not want them assume that they have sent it broke was ok then pretty upset the next day returned which further were Surcharges course close great good 2 weeks later they arrived then repaired functioned also equal properly but the sound is give these 2 boxes to let's say below average the bass is not strong and the treble sound very unclean've really me not expecting much so I was not disappointed by them but I honestly would invest more money rather be back in the future I encourage also all interested!
