• 15" neodymium woofer offers 400Wrms continuous power
handling and 98dB sensitivity
• Innovative approach to heat management utilises front mounted
(inverted) neodymium magnet assembly
• High-flux motor assembly enables greater sensitivity and higher
damping for dynamic bass/low-mid applications
• 4" high temperature Inside/Outside voice coil efficiently dissipates
heat, preventing sensitivity loss through thermal compression
