Conclusion:

Sound: First class 53 Points
Overall rating: good - very good 72 Points

The combination strikes up airy and precisely and let hear pleasant highs without any underexposure. Even at conventional surround sound the speaker set acquits itself well. ... Especially the exact and effortlessly reproduced spatiality in gauge and base fascinates.... So home cinema really amuses even by watching the row movies. The chase sequence at the beginning of “Quantum of solace”... comes with powerful impulses and satisfies with believably play of space simuation. The speakers from Hannover hit the right tone in stereo mode, too. Here they even more enthuse with their superb spatial presentation due to the fantastic fine resolution of the ribbon tweeter.”

Conclusion:

av-wertung: very good 83 from 100
