I25 – modular integrated amplifier

• Thiel CS1.2 Loudspeaker Design – The Thiel CS1.2 is a time- and phase-coherent two-way floorstander engineered to deliver precise imaging, natural transient behaviour, and exceptional coherence for discerning audiophiles.

• Coaxial Performance Precision – Leveraging Thiel’s acclaimed first-order crossover topology, the CS1.2 offers seamless driver integration, producing a smooth, uncoloured midrange with excellent detail retrieval across complex musical passages.

• Rigid Cabinet Construction – The Thiel CS1.2 features a heavily braced enclosure designed to minimise resonances, ensuring tighter bass performance, greater articulation, and more stable imaging presentation in real-world listening rooms.

• Neutral and Transparent Sound – Known for its accuracy, the Thiel CS1.2 reveals micro-details with minimal tonal coloration, providing a truthful, reference-style presentation that rewards high-quality upstream electronics.

• Dimensions – Approx. 864 mm (H) × 279 mm (W) × 330 mm (D), a compact yet substantial footprint suited for both medium and smaller dedicated listening spaces.

• Weight – Each speaker weighs about 22 kg, offering improved vibration control and stable coupling to the floor for enhanced dynamic response.

• Thiel CS1.2 Overview – The Thiel CS1.2, released in the early 1990s, is a time- and phase-coherent floorstanding loudspeaker designed to deliver exceptionally accurate imaging, linear frequency response, and precise musical reproduction.

• Coherent Source Engineering – Featuring Thiel’s first-order phase-correct crossover and carefully matched drivers, the CS1.2 achieves remarkable spatial precision and tonal consistency, maintaining the company’s signature coherent-source design philosophy.

• Dynamic and Detailed Performance – The Thiel CS1.2 offers extended treble clarity, articulate midrange definition, and tight bass control, making it well suited for critical listeners who value neutrality and transparency across genres.

• Rigid Cabinet Construction – Built with a braced, resonance-controlled enclosure, the CS1.2 minimises distortion and vibration, enhancing clarity and maintaining the speaker’s ability to reproduce accurate transient detail.

• Dimensions – Approx. 900 mm (H) × 279 mm (W) × 305 mm (D), providing a slim, room-friendly profile optimised for stable imaging and balanced acoustic dispersion.

• Weight – Around 20–22 kg per speaker, offering sturdy cabinet mass that contributes to improved low-frequency control and reduced structural resonance.

• Full-Range Speaker Overview – The Thiel CS5 delivers a time-coherent, phase-accurate full-range design using first-order crossovers, offering exceptionally precise imaging, tonal accuracy and wide-band musical realism for high-performance reference systems.

• Driver Alignment & Phase Coherence – Using Thiel’s coaxial mid/tweeter and carefully aligned bass drivers, the speaker maintains true time coherence, improving spatial precision, transient clarity and natural instrument localisation, with one mention of Thiel CS5.

• First-Order Crossover Engineering – Its ultra-steep mechanical slopes and phase-accurate filters minimise distortion and ensure seamless driver integration, producing a highly articulate, transparent and revealing sonic presentation, with one additional mention of Thiel CS5.

• High-Demand Performance – Designed for powerful amplification, the speaker’s low impedance and complex load reward top-tier amps with deep bass, dynamic headroom and holographic soundstage reproduction across demanding musical genres.

• Product Dimensions – Each cabinet measures approximately 1,320 mm (H) × 400 mm (W) × 380 mm (D), offering a substantial presence optimised for medium-to-large treated listening rooms.

• Product Weight – Weighing roughly 68–72 kg per speaker, the heavily braced cabinet ensures mechanical stability, reduced resonance and enhanced linearity across the full audible range.
