One of the most important aspects in the process of design at Hornmanufaktur is to avoid standing waves and resonances, which would otherwise spoil the great fidelity of reproduction.The sides of the speaker cases are realized in sumptuous sandwich construction (several layers), restrained using braces and layers of bitumen. This approach yields a high inner density, nipping resonances in the bud. The lavish curves prevent standing waves before they can even develop. Cavities are filled with sound-absorbing material.The resulting precision certainly is one of the keys to success.
