Passive Hi-Fi Subwoofer Box

■ Newly optimized external suspension (surround) to improve large signal handling
■ Extremely rigid aluminum diaphragm to ensure piston movement at high levels, with better heat dissipation and high continuous power levels
■ Two internal aluminum rings for stabilizing the magnetic field, leading to lower high-frequency distortion
■ Heavy-duty black glass fiber voice coil reducing mechanical losses, resulting in better dynamic performance and low-level detail retrieval
■ Black anodized magnetic structure steel parts for increased heat dissipation and power handling
■ Special designed CONEX dampers (sprung spiders) for durability under extreme working conditions
■ Four-layer voice coil design increases control and provides better performance in small enclosures
