WF166TU02  6" die cast car woofer, 4 ohm

 

 

 

 

 

WF166TU02 car mid/wooferWF166TU02 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 1” 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.
