BlieSMa T25S-6 25mm Silk fabric dome tweeter 6 Ohm

Main feature of Bliesma T25S-6 tweeter is extremely low moving mass (0.16 g), offering better transient responce and higher efficiency.

Flush mounted surround (also made of fabric) and rear mounted magnet system result flat frequency response and wide off-axis diagram.

Neodymium motor has copper sleeve for low non-linear and modulation distorsions. No ferrofluid is used for better dynamics. Underhung CCAW-voicecoil is wound on titanium former.

Mounting flange and rear chamber are made of aluminium. Rear chamber is filled with natural wool for better damping.

Characteristics :

• 25mm silk fabric dome and silk fabric surround.
• Special proprietary material for dome and surround to ensure the best possible sound.
• Extremely low moving mass for improved dynamics, response and higher efficiency
• Fully saturated copper-capped neodymium motor for low non-linear distortion and exceptionally low intermodulation distortion 2 mm linear excursion and large vent channel for undistorted reproduction at low frequencies
• Narrow surround for less tone coloration through soft elements.
• Sound generation only through the aluminum membrane, which is rigid up to 35kHz
• Flush-mounted surround and rear-mounted magnet system for a flat frequency response and a wide off-axis response.
• No ferrofluid for improved dynamics
• Copper-coated aluminum underhung voice coil on titanium bobbin
