Bliesma Audio beryllium dome tweeter, Neo magnet 4Ohm, T34B-4

Bliesma Audio beryllium dome tweeter, Neo magnet 4Ohm, T34B-4

Features :

• 34mm beryllium dome with ultrasonic first breakup mode

• Flush mounted surround and rear mounted magnet system for flat frequency response and wide off-axis response

• Extremely low moving mass for better transient response and higher efficiency

• No ferrofluid for improved dynamics

• Underhung voice coil wound on titanium former

• Fully saturated neodymium motor with copper sleeve for low non linear and modulation distortion             

• 3mm linear excursion and large vent channel for undistorted low frequency operation

• Narrow surround for less "soft dome" coloration

• Flexible and lightweight lead wires made in Denmark

‘• Thick aluminium powder coated flange

• Aluminium rear chamber with natural wool damping

• Gold plated wire terminals

• Extremely wide recommended frequency range 1.3kHz-35kHz
