I had previously a Bose Acoustimass 10 which has cost almost as much as this system here, the Bose system is the hell system a joke with start, I have never in my life seen such a difference in quality (part) that would have Bose speakers purely from the performance and the sound for comparison with this system, no 500 value! The bass of the devil system are bone dry and really hard thanks to the 2 really stark bass boxes that Satellite bring a very beautiful crystal clear sound forth as the two dipoles in the rear area, value of this system is almost too good, I had over 5 years hesitated me to opt for the devil and because you may try it in hell yes, I risked it, and WOW, the Bose system was sold immediately. With Bose now I'm sure that this has only to do with prestige, sonically this Brüllwürfel are just crap ...
