Description
Top-quality dome midrange driver with a TeXtreme membrane.
TeXtreme is an ultra-rigid carbon fiber material that, due to its outstanding sonic properties, is already used in several top-of-the-line speaker drivers (SB-Acoustics, Perlisten Audio, etc.).
Compared to the M74A-6, the M74T-6's membrane resonance is shifted to a higher frequency and better damped, the membrane mass is lower, and the efficiency is higher. Only the M74B-6 with its beryllium cone remains unmatched.....
Features:
74 mm TeXtreme dome with a high stiffness-to-weight ratio
Unusually wide dispersion pattern
Excellent transient response and high efficiency (95.5 dB @ 2.83 V)
Recommended frequency range: 400 Hz-6 kHz
Cone resonance at approximately 13 kHz
Extremely low moving mass for improved dynamics, responsiveness, and higher efficiency
Fully saturated neodymium motor with copper cap for low nonlinear distortion and exceptionally low intermodulation distortion
2.4 mm linear excursion and large vent channel for undistorted low-frequency reproduction
Flush-mounted surround and rear-mounted magnet system for a flat frequency response and a wide off-axis frequency response.
No ferrofluid for improved dynamics
Underhung voice coil made of copper-clad aluminum on a titanium bobbin
Flexible and lightweight connecting wires, made in Denmark
Thick, powder-coated aluminum flange
Aluminum rear chamber with natural wool damping
Gold-plated wire leads
