Audison Thesis TH 1.5 II violin

Audison Thesis TH 1.5 II violino - 38mm Dome Tweeter for precise highs in the vehicle

The Audison Thesis TH 1.5 II violino is a 38mm dome tweeter that delivers clean, detailed highs and high dynamics in the vehicle. The combination of a single-layer 34mm CCAW voice coil, powerful neodymium motor, and the TH 1.5 II Tuning System ensures controlled behavior up to the highest frequencies. With up to 200 W peak power handling, 6 Ohm impedance, and optimized off-axis performance, the tweeter is ideal for high-quality 2- or 3-way setups. Audison's eID technology also supports product traceability. Available at Carhifi.shop.

Technical Highlights

• Single-layer 34mm CCAW voice coil: low weight, high control and low distortion even at lower crossover frequencies.
• Powerful neodymium motor (custom, N38 H-Grade) with 1.67 T·m in the air gap for high dynamics and clean transients.
• Exclusive air load system: resonance frequency below 800 Hz, allows filter settings from approx. 1.5 kHz with 12 dB/Oct.
• 38mm natural silk dome made of Tetolon fiber, analyzed by laser vibrometer and FEM - for a smooth, extended frequency response.
• Optimized for off-center mounting with linear response up to 26 kHz.
• TH 1.5 II Violino Tuning System: optional back chamber or back plate for maximum integration freedom in the vehicle.
• Solid metal construction, exclusively developed for the TH 1.5 II.
• FEM-optimized faceplate and spokes for clean dispersion.
• eID technology for unique traceability from the manufacturing process to the owner.

Installation & Compatibility

The TH 1.5 II violino integrates into high-quality front systems, especially if you prefer a clean off-axis installation. The combination of low resonance frequency and stable motor allows for deep coupling to the midrange speaker. Plan the crossover depending on system power and positioning from about 1.5–1.8 kHz with 12 dB/Oct. The TH 1.5 II Tuning System (back chamber or back plate) helps you to integrate the tweeter optimally – acoustically and visually.
