      Wavecor Speaker Driver - WF152BD06- 8 Ohm 6" Glass Fibre Cone Mid-Woofer

      Description
      The 6” transducer WF152BD06 (8 ohm) was designed as high performance bass and midrange units for compact monitors and high-end hi-fi speakers.

       

      Features

      • Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
      • Copper cap on center pole to reduce voice coil inductance and to minimize variations in voice coil inductance as a function of voice coil position
      • Cone made of a new paper/glass fiber mix with improved consistency and stability
      • Rigid die cast alu chassis with extensive venting for lower air flow speed reducing audible distortion
      • Vented voice coil former for reduced distortion and compression
      • Vented center pole with dual flares for reduced noise level at large cone excursions
      • Heavy-duty black fiber glass voice coil former to reduce mechanical losses resulting in better dynamic performance and low-level details
      • Large motor with 1¼” 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 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

      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.
