Let’s take a look at the woofer

There is no woofer like the one in SA legend 40.2 silverback. Here you find the main reason for the loudspeaker’s incredibly big sound.

The membrane moves 40% more than normal, and you experience a deeper bass and a richer sound than other speakers of the same size.

The membrane is made of carbon fiber. The lightweight material helps make the sound clearer and more vibrant, and you get a clear sense of being close to the music.

Experience bass down to 20 Hz

For the first time, you can experience bass down to 20 Hz. Together with the built-in amplifiers and digital signal processors, the powerful woofers operate down to 20 Hz.

This is not possible for traditional loudspeakers. The sound is bigger and richer than ever before and the integrated and intelligent electronics even protect the woofers from overload.

Fills the living room with sound

The tweeter in SA legend 40.2 silverback is newly developed with the patented DTX acoustic lens.

This means that the sound covers the entire room. You do not have to sit in a certain place to get the best experience.

The extremely lightweight membrane makes the sound delicate and nuanced so you never miss the magic of the music.
