Lens Resonance System® 

The patented Lens Resonance System® (LRS) is a groundbreaking soundboard technology. Kauko Liikanen and Uwe Florath began developing the system in the 1990s, and after numerous prototypes, they achieved a design featuring thinner, more flexible edges with a stiffer center. One of the key advantages of this structure is the even tone and consistent sound across the fretboard.

LRS produces a colorful, bright tone with delicate, effortless nuances that serve guitarists from beginners to advanced players. Even with minimal effort, plucking the strings results in a strong sound with long sustain. This allows every player to access a rich tonal palette, helping the music come to life through the guitar.

Patented in 2000, LRS has been used in handmade Liikanen Guitars and in factory-made models, now known as Riento® Guitars. The Lens Resonance System® is exclusively featured in all Riento® classical guitars, paired with a solid wood top.
