Wavecor SW270WA01 10½" air-dried paper cone subwoofer 4 Ohm
The 10½" transducer SW270WA01 was designed specifically for high performance subwoofer applications where sound quality and low distortion are the priorities. It features the Wavecor Balanced Drive motor technology.
FEATURES
Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
Extremely large linear stroke, Xmax = 11 mm, ensuring low distortion at high output levels
Very rigid air dried paper cone cone to ensure piston motion at high levels for reduced distortion
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 black fiber glass voice coil former to reduce mechanical losses resulting in better dynamic performance and low-level details
Large motor with 2” voice coil diameter for better control and power handling
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 platedd 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
