25TF - 1inch Tweeter
Ordering code: 25TF-065
• Ultra low distortion
• Frequency range: 1,000 Hz – 30,000 Hz
• Titanium Nitride dome
• Advanced ferrite magnetic structure, with tuned resonant
chamber
• 20.4 mm dia, aluminum former voice coil assembly
• High sensitivity 91.5dB 1 watt / 1 meter
• 20 watt AES / 40 watt program power handling
• Ideal for use in high quality Hi-Fi or proffessional audio
applications, where the low distortion and extended high
frequencies are desired.
The 25TF is a high efficiency, (91.5dB 1watt / 1 meter)
1.0-inch tweeter with incredibely linear frequency response
characteristics, high power handling capability while generating ultra low harmonic distortion artifacts.
