HECO writes :”Paper is not simply paper, even if the material used in loudspeaker construction is legendary. That’s why many of our cones in woofers and mid-range speakers are made of Kraft Papier. This consists of Nordic coniferous wood fibres, as these are particularly strong. By blending in about 5% wool threads, both materials unite to form a solid material with high internal damping. This results in a particularly light but very stable construction when the membrane is pressed. This is precisely what makes a loudspeaker perfect. Kraft Papier can be found in many of our products, including of course our new flagship La Diva.”
