Wavecor SW182BD03 7" Balanced Drive Black Aluminum Cone Subwoofer 4 Ohm

Key Features

• Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
• Very rigid aluminum cone to ensure piston motion at high levels and for better heat transfer at high continuous power levels
• 4-layer voice coil for increased control and better small-cabinet performance
• Built-in aluminum field-stabilizing rings for reduced distortion at high levels
• Rigid die cast aluminum chassis with extensive venting for lower air flow speed reducing audible distortion
• Vented center pole with dual flares for reduced noise level at large cone excursions
• Vented voice coil former for reduced distortion and compression
