Recommended by Acousticians
<\/strong>We are very pleased that our diffusers are recommended by numerous acousticians. <\/span>
The product development was a long and intensive way. We would be happy to give you even more information about our diffusers here:<\/span><\/p>

Production with the most modern techniques
<\/b><\/span>Adelsklang diffusers are precisely cut to tenths of a millimeter in Germany using the most modern manufacturing methods and elaborately processed by experts to create the final product.\u00a0<\/span>10 years ago, it would probably have been impossible to produce a diffuser of this type and quality.<\/span><\/span><\/p>

The right material
<\/b><\/span>Two aspects are particularly important for the material of diffusers, the sound hardness and the sonic properties of the material.
<\/span>If the direct sound is reflected by a surface, the tonal properties of the indirect sound are shaped by this surface. This is also one of the reasons why a room with stone walls sounds different from a room with wooden walls.
<\/span>After numerous measurements and listening tests of various materials, birch wood has turned out to be the best material by far. It combines sound hardness and sonic properties in an almost perfect way for an acoustic diffuser.\u00a0
<\/span>To ensure quality and maximize tonal characteristics, we use only cross-laminated premium birch wood from sustainable forests.<\/span><\/span><\/p>

The right material thickness
<\/b><\/span>In QRD diffusers, also known as Schroeder diffusers after the physicist Manfred Schroeder, the so-called fins between the individual chambers play an important role.\u00a0<\/span>For the fins, the general rule is: the thinner, the better. That's why we use only sound-hard birch wood with a thickness of 3 mm for our diffusers.\u00a0<\/span>Due to our elaborate manufacturing process with Comb Joint frame joints, we achieve a rigidity and stability that is second to none.<\/span><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
