10 1/2" Subwoofer, air-dried paper cone, 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.

  • 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
