New Aluminium Cone Technology
Current aluminium cone speakers are simply conventional designs with an aluminium cone replacing their paper, polypropylene or other material counterparts. The power capacity of these conventional aluminium cones is limited because of break up problems between the edge of the aluminium cone and the rubber surround. Furthermore there are unwanted resonances on the cone material which cause extremely high distortions shown in some peaks in the upper frequency range. The resulting sound is crisp and metallic.
Our DEGO engineers have solved these problems by developing a totally new aluminium cone:

Our DEGO engineers have solved these problems by developing a totally new aluminium cone:
- We use an ultra-light, rigid and stiff aluminium membrane specially prepared in an anodizing process, which allows a dramatic increase in sound velocity, or what we call “sonic speed”. That means impulses from the voice coil spread radial to the edge of the aluminium cone for times faster than on other cone materials.
- We have optimized the shape of the rubber surrounding. A special adhesive connection the metal cone and the rubber surround guarantee extremely high power handling.
- We have computer designed the shape of the aluminium cone using some exactly optimized R.A.C.E. (Resonance Attenuation Cone Embossment) to avoid breaking up resonances at the high frequencies. Therefore the sound is distortion and coloration-free across the entire audio spectrum. The music reproduction is clearly more dynamic, precise and detailed but without any sharpness and metal sound coloration.
