The S 430

Mag50 In-house treble driver

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.

Bass Systems

Symmetric Directivity System

Regardless of whether you are an enthusiast or just an occasional listener: you can rely on T+A loudspeakers to focus on natural sound and music reproduction true to the original. Therefore, the entire mid- and treble range are transmitted by a system consisting of two aluminum mid-range drivers and a concentric magnetostatic tweeter. This system, which we term Symmetric Directivity, combines dynamic advantages with a well-defined sound dispersion behaviour. By using two 15 cm Star Stabilizer midrange drivers, the excursion of each individual chassis is halved, the distortion factor is reduced, and the linearity is increased. The precisely calculated control of the mid-range drivers and the Mag50 tweeter by the FSR crossovers significantly reduces disruptive room influences caused by indirect sound and reflection. As a result, the Symmetric Directivity System ensures a large sound stage, real depth, perfect signal response and precise localization of all voices and instruments.

Cross Over Unit

The Solitaire S speakers are equipped with very complex, double-sided Fast Signal Response (FSR) three-way crossover units. These extraordinary crossovers play a crucial part in the outstanding imaging and dispersion characteristics of the system as a whole. The earth has a dedicated layer in order to ensure that even very high currents and large signals can be processed without distortion. Accurately calculated and optimised for superb transient and transmission behaviour, they effortlessly process even extremely high levels, and ensure that all three frequency ranges are correctly driven. The filter stages and bandpasses are optimised for phase and group timing. We even employ special cable for the internal speaker drive unit connections. Since the magnetostats are capable of handling more than 50 kHz, we use our own co-axial cable which can reproduce even the highest frequencies without losses. Bass, mid and treble ranges can be fine-tuned by means of switches. Since the circuit boards for the bass and mid-range areas are completely separate from each other, the Solitaire S is ideal for use in bi-amping arrangements.
