    Wavecor Speaker Driver - WF166TU2 - 4 Ohm 6" Die Cast Car Woofer

    Description
    WF166TU02 is a mid/woofer designed for demanding bass and midrange applications. It works equally well for most applications but is designed especially for automotive high-end sound.

    The very rigid die cast alu chassis follows the common standard dimensions for easy installation in cars WF166TU02 is powered by a large 90 mm magnet structure that ensures good efficiency and optimized T/S parameters.

    The large 32 mm voice coil ensures high power handling - thermally and mechanically The optimized paper cone ensures wide bandwidth and low distortion. Distortion is further reduced by efficient venting and a separate alu field-stabilizing ring. WF166TU02 is a good choice for 2-way car speaker systems.

     

    Features

    • Very rigid die cast alu chassis
    • Built-in alu field stabilizing ring for reduced high-level distortion
    • Vented voice coil former for reduced distortion and compression
    • Vented chassis for lower air flow speed reducing audible distortion
    • Heavy-duty black fiber glass voice coil bobbin to increase power handling and reduce mechanical losses resulting in better dynamic performance and low-level details
    • Large motor system with 1¼” voice coil diameter and large 90 mm magnet for better control and efficiency
    • Linear suspension with specially designed
    • CONEX damper (spider) for long durability under extreme operating conditions
    • Gold plated terminals to prevent oxidation for long-term reliable connection - important in a car environment

    Note 6 It is generally a rough simplification to assume that loudspeaker transducer voice coils exhibit the characteristics of an inductor. Instead it is a far more accurate approach to use the more advanced model often referred to as the “Wright empirical model”, also used in LEAP-4 as the TSL model (www.linearx.com), involving parameters Krm, Erm, Kxm, and Exm. This more accurate transducer model is described in a technical paper (PDF) here.
    Note 7 After burn-in specifications are measured at least 12 hours after exiting the transducer by a 20 Hz sine wave for 2 hours at level 10 VRMS. Unit are not burned in before shipping.
