T500A Mk III
Horn Super Tweeter-
Development Award
The highest grade horn super tweeter with a newly developed ring-shaped pure magnesium diaphragm, a horn and equalizer made of precision-machined solid brass, and an Alnico magnet internal magnetic circuit with a low distortion design.
Features
Ring-shaped pure magnesium diaphragm
The newly developed ring-shaped pure magnesium diaphragm has minimal metallic characteristic squeal, and the material thickness and surface treatment are optimized to achieve penetrating ultra-high frequency reproduction.
Platinum-plated brass horn/equalizer
Precision-machined solid brass cylindrical horn and equalizer are mounted. Platinum plating on the surface treatment provides fast rise time and natural, highly transparent sound.
Alnico magnet internal magnetic circuit
The magnetic circuit, consisting of two layers of Alnico magnets, has a strong magnetic flux density, and copper plating on the surface of the pole piece reduces current distortion, resulting in reproduction of high resolution sound quality.
Copper machined gold-plated terminals / Copper/silver alloy internal wiring
For the input terminals, gold-plated terminals (copper cutting) compatible with banana plugs are used. The internal wiring uses a single φ1.4mm copper/silver alloy wire with high sound quality.
Tungsten diaphragm ring
The diaphragm ring supporting the diaphragm uses a tungsten sheet with a high vibration-damping effect to reduce sound quality deterioration caused by unwanted vibrations.
Walnut veneer finish tweeter base
A tweeter base is included to securely support the heavy tweeter body. The surface is covered with walnut veneer and colored dark brown for a soothing appearance.
