More info

The 8¾” transducers SW223BD02 (4 ohm) and SW223BD03 (8 ohm) were designed specifically for high performance compact subwoofer applications where sound quality and low distortion are the priorities.

  • Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
  • Extremely large linear stroke, Xmax = ± 10.7 mm, ensuring low distortion at high output levels
  • Very rigid black aluminium cone to ensure piston motion at high levels and for better heat transfer at high continuous power levels
  • Rigid die cast alu chassis with extensive venting for lower air flow speed reducing audible distortion
  • 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 plated cone and 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
