Horn super tweeter with newly developed ring-shaped titanium diaphragm

The T90A-ST is a horn super tweeter based on the T90A with a newly developed ring-shaped titanium diaphragm to further improve sound quality. Combined with the well-established low distortion Alnico internal magnetic circuit, it has a sufficiently wide reproduction frequency bandwidth with extended high frequency range and excellent transient, and the aluminum alloy horn and equalizer provide clear and penetrating musical expression at a more user-friendly sound pressure. This is a special limited-production unit that can be added to various speaker systems, including back-loaded horn systems, to enjoy a natural, clear, and high-definition sound field.

Features

– Newly developed ring-shaped titanium diaphragm
We have newly developed a titanium diaphragm molded into a ring shape. It has excellent transient and emits clear and penetrating sound.

– Low distortion Alnico internal magnetic circuit
Alnico magnets are used, possessing high magnetic flux density despite their small size. In addition, the surface of the pole piece is copper plated to reduce current distortion and achieve high sound quality.

– Aluminum alloy thick-walled cylindrical horn and equalizer
A precision-machined aluminum alloy thick-walled cylindrical horn and equalizer are installed to provide a delicate and natural sound quality with moderate resonance.

– Gold-plated terminals compatible with banana plugs & copper/silver alloy wire materials
Gold-plated terminals compatible with banana plugs are used for the input terminals. In addition, for the internal wiring, ultra-thick copper/silver alloy single wires of Φ1.4mm are used to achieve high sound quality.
