    Wavecor SW118WA01 10 cm subwoofer 4 ohm

     

    4½” High Performance Steel Frame Subwoofer Units.
    Suitable for dedicated subwoofer applications  and as low frequency transducers in 2½-, 3- and multi-way speaker systems.

    • Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
    • Large linear stroke, ensuring low distortion at high output levels
    • Rigid paper cones to ensure piston motion even at high levels - for reduced distortion
    • Rigid steel chassis’ with extensive venting for lower air flow speed reducing audible distortion
    • Heavy-duty fiber glass voice coil former to reduce mechanical losses resulting in better dynamic performance and low-level details
    • Large motor structures for better control and power handling
    • Built-in alu field-stabilizing rings 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
    • Delivered with foam gasket attached for hassle-free mounting and secure cabinet sealing
