Concerning sound aspects, flexibility ist the key. The HDA 6,5 Amplifier can definitely be called flexible. Via two crossover networks, satellite cabinets as well as the subwoofer can be set in a way that you are able to change from background music to hot party sound with a strong base. To keep everything clean the fan grill is very helpful, as taking it down is very easy.
