Wavecor SW275BD01 Woofer 25 cm paper cone

10.75" Ultra-High Performance Subwoofer Unit
When nothing but the most extreme in bass output and performance is required.
Very low distortion from below 20 Hz

FEATURES

Extreme overhung voice coil with +/-16mm of linear stroke to ensure lowest distortion at very high drive levels
FEA optimized suspension for improved symmetry and lower distortion
Very large motor structure with 2.5” voice coil for better control and power handling
Balanced Drive motor for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
Rigid Foamed Paper cone to ensure piston motion even at high levels - for reduced distortion
Dual-spider design for higher mechanical durability and high-excursion stability
Rigid die cast alu 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
Heavy-duty fiber glass voice coil former to reduce mechanical losses resulting in better dynamic performance and low-level details
Built-in alu field-stabilizing ring for reduced distortion at high levels
Low-loss suspension (high Qm) for better reproduction of details and dynamics
Black plated 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
