The core of the Solitaire S 430 is the hand-made Mag50 magnetostat, which has been developed and produced entirely in Herford. Although fundamentally based on the TPM 3100 and TPM 2500 headphone transducers, this unit incorporates a large number of innovative developments which make it more than just a unique member of the T+A magnetostat family: it really stands as a symbol of our love of music and our belief in science for the best possible reproduction of sound. Its internal construction consists of a WaveArray conductor - developed specifically for this application - whose conductive aluminium is etched onto a carrier film using a photo-chemical process. The slightly undulating course of the conductors is carefully calculated to prevent harmful linear modes. A Draft Control System, adopted from the Solitaire P-SE and modified for use in loudspeakers, ensures that the flow characteristics in the Mag50 are efficient, and turbulence at the magnets is minimised, so that even the tiniest negative influences are eliminated. In spite of its length of just 50 millimetres, the ten magnets - arranged in two rows - of the Mag50 constantly deliver ample drive power for impressive sound levels, while the harmful distortion normally generated by small magnetostats is eliminated before it can develop, by the deliberate modulation of the magnetic field and refined damping and absorber measures. In terms of sound quality the Mag50 offers the precision, speed and resolution of an electrostat, but without the need for a supplementary power supply.
