SA legend 60.2 silverback fulfill the music lovers dream of greater sound experiences. It does`nt have much in common with a normal loudspeaker. 4 built-in amplifiers with a total power of 560 Watts and a frequency response to 17 Hz tell in their own way that this is something special. The combination of digital signal processing and stunning acoustic craftsmanship enable SA legend 60.2 silverback to meet challenges where traditional loudspeakers give up.
These are the unique benefits: * Experience the sound of all instruments, even when playing at low volume. For most of us this is 95% of the time. The adaptive bass system creates a big sound image where you can even hear the deepest bass when playing at low volume. It's a fantastic experience. Traditional speakers can't do this, regardless of price or brand.
* Enjoy the natural sound. SA legend 60.2 silverback is created in respect for music. It does'nt add or subtract anything from the sound. The special designed drive units and signal processors create an incredibly musical and natural sound balance.
* Enjoy more nuances in the sound. SA legend 60.2 silverback is built without passive components that destroy music nuances in normal speakers. Instead, you find digital circuits that process the sound without loss or limitations.

Product Strengths
