• Double Stacked Magnet Assembly — combined with a long wiring width of voice coil allows for long excursions with reduced distortion
• Kapton® Voice Coil Former — offers higher power handling than aluminum voice coil formers, as well as extremely efficient cooling properties
• 4 Layer Voice Coil — keeps more wire in the magnetic gap for better output
