      Wavecor Speaker Driver - WF152BD04 - 4 Ohm 6" Die Cast Paper Cone Mid-Woofer

      Description
      These 6" transducer WF152BD04 (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
      • Black coated semi-air-dried paper cone
      • 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 1 Measured in infinite baffle.
      Note 2 Tested in free air (no cabinet).
      Note 3 Measured using a semi-constant current source, nominal level 2 mA.
      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.
      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.
