■ Horn Super Tweeter

Introducing the T925A-ST, the first limited edition model of a long-selling horn super tweeter with over 30 years of history, featuring a newly developed ring-shaped titanium diaphragm.
Since its introduction in 1994, the T925A has long been a best-seller, supported by many passionate audiophiles as a horn super tweeter equipped with an alnico magnet. Now, we have developed the T925A-ST, the first limited edition model in its more than 30-year history. Equipped with a newly developed ring-shaped titanium diaphragm, the T925A-ST further enhances sound quality through adjustments to the renowned large, low-distortion alnico inner magnet magnetic circuit. This delivers clear, penetrating musical expression with extended high frequencies and excellent transients at a user-friendly sound pressure level. This special unit can be added to a variety of speaker systems, including back-loaded horn systems, to enjoy a natural, clear, high-definition sound field.

■ Newly Developed Ring-Shaped Titanium Diaphragm
We have developed a newly developed titanium diaphragm molded into a ring shape. It delivers clear, penetrating sound with excellent transient response.

■ Low-distortion Alnico inner magnetic circuit
Using an Alnico magnet, it possesses high magnetic flux density despite its compact size. Furthermore, copper-plated pole piece surfaces reduce current distortion, resulting in high-quality sound.

■ Thick-walled aluminum alloy cylindrical horn and equalizer
Equipped with a thick-walled aluminum alloy cylindrical horn and equalizer that are precisely machined to befit a limited edition model, it delivers delicate, natural sound quality with just the right amount of resonance.

■ Gold-plated terminals and copper-silver alloy wire compatible with banana plugs
The input terminals use gold-plated terminals compatible with banana plugs. Furthermore, the internal wiring uses extra-thick 1.4mm diameter copper-silver alloy solid wire for high sound quality.
