What is LRS?

The “Lens Resonance System^®” (LRS) is a unique patented soundboard construction for acoustic guitars and other musical instruments with a flat or near flat soundboard.

LRS is invented by Kauko Liikanen and Uwe Florath, in the workshop of Liikanen Musical Instruments, Helsinki/Finland. After two years of experimenting and developing, LRS soundboards are used in all “Liikanen Guitars” since year 2001.

Kantare Guitars is a new brand build exclusively with LRS.

 

How does LRS work?

The LRS soundboard is stiffened with a wooden cross-brace grid in the middle of the lower part of the soundboard. A thin plate of wood is glued over the grid. The cross-section of the whole construction is a lens shape and the soundboard around the bridge area is much stiffer and better controlled than in traditional soundboards.

The sound of a LRS guitar is very sensitive and responsive with an exceptional good sustain, because the vibration energy produced by the strings is evenly shared to the soundboard via the stiff middle area. The resonance- curves of   LRS-tops are more even than in traditional built guitars. There are no high-gained amplitude-peaks which yield to an unharmonic sound and often wolf-notes in the discant frequency range.

What does it give to you?

• the sound is more under your control

• you get a beautiful well balanced and clear classical guitar sound with a minimum of unharmonicity

• better sustain

• superior playability

• with a LRS-top you enjoy more about your guitar playing
