    Wavecor Speaker Driver - WF168WA02 - 8 Ohm 6" Paper Cone Mid-Woofer

    Description
    Nominal impedance is 4 ohm for WF168WA01 and 8 ohm for WF168WA02. Otherwise the two models are identical.

    WF168WA01/02 are mid/woofers designed for demanding bass and midrange applications. It works equally well for high-end hi-fi, high quality home theater systems, and monitoring setups.

    Powered by a large 90 mm magnet structure that ensures good efficiency and optimal T/S parameters. The large 32 mm voice coil ensures high power handling - thermally and mechanically

    The optimized paper cone ensures large bandwidth and low distortion. Distortion is further reduced by efficient venting and an alu shorting ring stabilizing the magnetic field in the air gap. WF168WA01/02 are very good choices for medium sized 2- way speaker systems

     

    Features

    • Alu field-stabilizing ring inside magnet assembly for reduced high-level distortion
    • Vented voice coil former for reduced distortion and compression
    • New 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 90 mm magnet for better control, power handling, and efficiency
    • Black magnet parts for better heat transfer to increase power handling
    • 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

    Note 4 Measured at 20 deg. C
    Note 5 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 6 After burn-in specifications are measured 12 hours after exiting the transducer by a 20 Hz sine wave for 2 hours at level 10/14.1 VRMS (4/8 ohm version). The unit is not burned in before shipping.
