Features

• 34 mm CCAW single layer voice coil combining lightweight, stability at lower frequencies, and total absence of musical transients compression.
• Extremely powerful custom N38 “H-grade” Neodymium magnet providing 1.67 T*m in the magnetic gap for superb dynamic response and very low distortion in the whole frequency range.
• The exclusive air-loading system results in a resonance frequency below  800 Hz, for filter set-up, starting as low as 1.5 kHz – 12dB/Oct.
• 38 mm natural silk dome optimized with 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-axis installation.
• TH 1.5 II Violino Tuning System features two types of electro-acoustic load: bottom case or bottom disk according to targets of highest performance as well as the flexibility of in-car integration.
• Full solid metal construction structure with each part exclusively designed and produced for the Audison TH 1.5 II.
• FEM (Finite Element Method) optimized faceplate and front spokes for an improved dispersion pattern.

• 50 mm mobile voice coil in CCAR (Copper Clad Aluminum Ribbon)  wound with flat wire to maximize the force factor and heat dissipation.
• Low inductance of the mobile voice coil to optimize the emission in the medium-high band (2-3 kHz).
• N48 “H-grade” neodymium magnet with superb thermal stability to  guarantee an optimal dynamic reserve in every situation.
• Magnetic group geometry 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 frequency response irregularities in the mid-high band, leaving the speaker interior in full view.
• Membrane geometry was designed using simulation software, to obtain a  smooth emission over all the listening angles.
• The basket is made of a single piece of die-cast aluminum featuring four pairs of spokes to optimize heat transfer, nullify turbulent airflows and ensure maximum structural rigidity.
• Hi-excursion suspension and spider, optimized with simulations of the loudspeaker multi-physical behavior.

• Construction without compromise with the use of high-quality resistors, capacitors, and inductors.
• Use of compensation networks for both woofer and tweeter, which optimize the load seen by the amplifier.
• Best envelopment filtering configuration with a well-distributed vertical scene along the entire height of the passenger compartment.
• 4 emission levels for the tweeter (-4, -2, 0, +1,5 dB) were designed using the L-Pad technique.
• Mid-frequency level control (-3-> 0 dB) centered at 900 Hz.
• Bi-amplification option.
