We found the answer in the two and half ways system we called Duetto. Growing out of the new Mia, Duetto is characteristic for its harmony and plasticity of reproduction. The enlarged working volume of internally separated chambers allows for best extension to low frequencies comparing to the new Mia. Mechanical decoupling from the floor is obtained by a new shaped HPL board with internal aluminium layers. The decoupling spikes will be screwed to this bottom board.
