Density (Kg/m3): The mass of an object divided by its volume.

Stiffness / Young's Modulus (Gpa):  Indicates the resistance of a piece to deformation under the action of an external force. The higher the stiffness, the lower the elasticity.

Resonance Frequency (Hz):  Number of vibrations per second. Each piece has a resonance frequency that characterizes its tone.

Sustain (Q Factor):  How long a piece will keep on ringing after being hit.

Acoustic Radiation Coefficient:  How much energy is necessary to excite a piece in vibrations. The lower the amount of energy, the higher the coefficient

Maderas Barber's new Alpine Spruce tops have undergone a rigorous sound analysis that will allow you to choose the one that best suits your needs based on its sound properties. This analysis has been carried out individually for each top.

When you choose a Top for your guitar, you are choosing the sound of your instrument. That's why we have created a sound catalogue where you can appreciate the acoustic beauty of each piece.
