Bliesma Audio beryllium dome tweeter, Neo magnet 6Ohm, T25B-6

Bliesma Audio beryllium dome tweeter, Neo magnet 6Ohm, T25B-6

Features :

• 25mm beryllium dome with 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 2.2kHz-40kHz
