Solitaire S 430

Magnetostatic precision, compact authority.

The Solitaire S 430 brings T+A's magnetostatic technology into a more accessible three-way floorstander. A Mag50 magnetostatic tweeter with WaveArray conductor and Draft Control System handles treble duties, while two 150 mm StarStabilizer midrange drivers and two 220 mm long-throw woofers deliver a rich, full-bodied sound. The Symmetric Directivity System ensures even, controlled dispersion, and the FSR crossover supports bi-amping for those who want to take performance further.

Key Features

Mag50 Magnetostatic Tweeter

A 50 mm magnetostatic driver with WaveArray conductor and Draft Control System delivers the same transient purity as the larger Mag850, scaled for a more compact design.

2× 150 mm StarStabilizer Midrange

Two embossed aluminium midrange drivers with star-pattern stiffening deliver detailed, distortion-free vocal reproduction.

2× 220 mm Bass Drivers

Two long-throw aluminium woofers with die-cast baskets provide deep, controlled bass response down to 29 Hz.

Symmetric Directivity & Bi-Amp Ready

Concentric driver arrangement for even dispersion, with separate FSR crossover boards at 200 / 2,200 Hz enabling bi-amping capability.

Technologies Inside

StarStabilizer Drivers

Piston-perfect cone motion.

T+A's StarStabilizer technology uses a star-shaped centre reinforcement with silicon powder coating and deliberately calculated conical arc geometry to prevent natural modes and self-resonances before they form. The result is a driver that behaves like a perfect piston during demanding playback — lightweight, stiff, and distortion-free across its entire operating range.

A loudspeaker cone should ideally behave as a rigid piston — moving uniformly across its entire surface. In reality, every cone material has resonant modes where different parts of the cone flex independently, creating coloration and distortion. Most manufacturers address this with heavy damping materials that suppress resonances but also reduce efficiency and transient speed. T+A's StarStabilizer takes a different approach: a star-shaped reinforcement structure is bonded to the cone, with each arm precisely calculated to break up the symmetrical resonance patterns that would otherwise form. The silicon powder coating adds controlled damping at the molecular level without adding significant mass. Combined with a deliberately calculated conical arc geometry — where the cone's curvature is optimised to direct vibrational energy toward the surround rather than allowing it to reflect back — the result is a driver that maintains true pistonic motion across its entire operating bandwidth. This means cleaner midrange, tighter bass, and more accurate transient response without sacrificing the efficiency and dynamic responsiveness that lightweight cones provide.

Solitaire Series

The pinnacle of T+A loudspeaker engineering.

The Solitaire range represents T+A's statement in loudspeaker design. The S 540 and S 530 feature the Mag850 — an 850 mm magnetostatic line-source tweeter driven by 64 high-performance magnets — paired with an array of oval StarStabilizer midrange drivers to create a true Cylinder Wave line source. The S 430 uses a Mag50 magnetostatic tweeter with the Symmetric Directivity System. All models employ double-sided FSR crossovers with switchable voicing.
