Upgraded 70 mm fullrange with extended bass response. Recommended for small systems, where frequency range, neutrality, and low distortion are the highest priorities. Also suitable for high definition full range line sources, with or without subwoofer assistance.
FEATURES
True full-range design with useable frequency range 100 Hz - 20kHz
Dual neodymium magnet structure for high efficiency and almost ideal magnetically shielding
Copper cap on center pole to reduce voice coil inductance and to minimize variations in voice coil inductance as a function of voice coil position
Black anodized alu cone for better heat transfer
Vented polymer chassis for lower air flow speed reducing audible distortion
Vented voice coil former for reduced distortion and compression
Heavy-duty black fiber glass voice coil bobbin to reduce mechanical losses resulting in better dynamic performance and low-level details
Large motor with 26 mm voice coil diameter for better control and power handling
Low-loss suspension (high Qm) for better reproduction of details and dynamics
Black motor parts for better heat transfer to the surrounding air
Conex spider for better durability under extreme conditions
Gold plated terminals to ensure long-term trouble free connection
