FEATURES

TH 1.5 II Violino

• Single-layer 34-mm CCAW voice coil with low weight, stability at low frequencies, and complete absence of musical transient compression.
• Extremely powerful custom N38 "H-grade" neodymium magnet with 1.67 T*m in the magnetic gap for excellent dynamics and very low distortion across the entire frequency range.
• The exclusive air-loading system results in a resonance frequency below 800 Hz, which at the filter setting already starts at 1.5 kHz - 12dB/oct.
• 38-mm natural silk dome, optimized through extensive material characterization, laser vibrometer scanning, and finite element analysis methods for a smooth and extended response.
• Frequency response up to 26 kHz, optimized for off-center placement.
• The TH 1.5 II Violino tuning system features two types of electro-acoustic loads: Bottom Case or Bottom Disk, depending on the goals of highest performance and integration flexibility in the car.
• All-metal construction, with every part exclusively developed and manufactured for the Audison TH 1.5 II.
• FEM (finite element method) optimized front plate and front spokes for improved radiation behavior.

TH 6.5 II Sax

• 50-mm voice coil made of CCAR (Copper Clad Aluminum Ribbon), wound with flat wire to maximize force factor and heat dissipation.
• Low inductance of the moving voice coil to optimize radiation in the mid-high band (2-3 kHz).
• N48 "H-grade" neodymium magnet with excellent thermal stability to ensure optimal dynamic reserve in every situation.
• The geometry of the magnet assembly was designed using finite element simulation software to maximize efficiency by concentrating the magnetic field in the gap.
• The diaphragm is made of TPX®, a transparent material that reduces irregularities in the mid-high frequency response and makes the inside of the speaker fully visible.
• The diaphragm geometry was designed using simulation software to achieve uniform radiation over all listening angles.
• The basket is made from a single piece of die-cast aluminum with four pairs of spokes to optimize heat transfer, avoid turbulent airflow, and ensure maximum structural rigidity.
• Hi-excursion suspension and spider, optimized with simulations of the speaker's multiphysical behavior.
