• 38mm natural silk dome optimized through extensive material characterization, laser vibrometer scanning and finite element analysis methods for consistent 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 objectives of maximum performance as well as the flexibility of integration in the car.
• Full metal construction, with every part designed and manufactured exclusively for the Audison TH 1.5 II.
• FEM (finite element method) optimized front panel and front spokes for improved radiation behavior.

• 50mm CCAR (Copper Clad Aluminum Ribbon) voice coil wound with flat wire to maximize power factor and heat dissipation.
• Low inductance of the mobile 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 group was designed using finite element simulation software to maximize efficiency by concentrating the magnetic field in the gap.
• The membrane is made of TPX® , a transparent material that reduces the irregularities of the frequency response in the mid-high range and makes the interior of the speaker completely visible.
• The membrane geometry was designed using simulation software to achieve uniform radiation across 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 multi-physics behavior of the loudspeaker.
