    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
