The speakers are really at its best. Have they integrated into a 5.1 system, more specifically replaced by my ELAC tower speaker. The sound I feel even better, mainly clearer and with a lot of power. And in quite small size. In addition, things look really chic and high quality. A brand product just made by Harman Kardon! Addendum: In order to let unfold the full power of the speakers also of course heard a corresponding receiver to do so. This work makes me a Yamaha RX-V473.
