WF132TU02    5¼" die cast car woofer, 4 ohm

 

 

 

 

WF132TU02 car mid/wooferWF132TU02 is a mid/woofer designed for demanding bass and midrange applications. It works equally well for most applications but was designed especially for automotive high-end sound systems. The very rigid die cast alu chassis follows the common standard dimensions for easy installation in cars.
WF132TU02 is powered by a large 90mm magnet structure that ensures good efficiency and optimized T/S parameters.
The large 32mm voice coil and the size of the magnet ensure high power handling - thermally and mechanically. The optimized paper cone ensures wide bandwidth and low distortion. Distortion is further reduced by efficient venting of chassis and voice coil.
WF132TU02 is an obvious choice for 2-way car speaker systems.

Ordering info

  • Very rigid die cast alu chassis to withstand challenging car applications
  • Built-in alu field-stabilizing ring for reduced high-level distortion
  • Vented voice coil former and magnet center pole 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 1.25” voice coil diameter and large 90 mm magnet for better control, power handling, 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 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 VRMS. The unit is not burned in before shipping.
