BlieSMa T25B-6

BlieSMa T25B-6 Beryllium Tweeter

High-sensitivity tweeter with 34-mm beryllium alloy dome.

• Nominal impedance [Zn]: 6 Ω
• Recommended frequency range: 2.2…40 kHz
• Sensitivity [2.83 V⁄1m]: 92.5 dB
• Resonance frequency [fs]: 1050 Hz
• Power [P]: 100 W (IEC 268-5)

Highlights

• 25mm aluminium-magnesium alloy dome with variable thickness for ultrasonic first breakup mode;
• Extremely low moving mass for better transient response and higher efficiency;
• Fully saturated neodymium motor with copper sleeve for low non linear and modulation distortion;
• 2mm linear excursion and large vent channel for undistorted low frequency operation;
• Narrow surround for less “soft dome” coloration;
• Flush mounted surround and rear mounted magnet system for flat frequency response and wide off-axis response;
• No ferrofluid for improved dynamics. Underhung voice coil wound on titanium former;
• Flexible and lightweight lead wires made in Denmark;
• Thick aluminium powder coated flange;
• Aluminium rear chamber with natural wool damping;
• Gold plated wire terminals;
• Recommended frequency range 1.8kHz-40kHz.
