WF168WA05/06     6½” glass fibre cone mid/woofers, 4/8 ohm

 

 

 

 

WF168WA05/06 are mid/woofers designed for demanding bass and midrange applications. They work equally well for high-end hi-fi, high quality home theater systems, and top multimedia setups, etc.
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 new optimized woven glass fibre cone ensures large bandwidth and low distortion. Distortion is further reduced by efficient venting and by adding an internal alu shorting ring to  stabilize the magnetic field in the air gap.

Important!
Please observe that these text files for download are actual measurements of the drivers measured in infinite baffle and without any enclosure. Measuring the drivers in a finite baffle (like the baffle of most speaker cabinets) and in any size of enclosure will lead to different response curves.

FEATURES

  • Glass-Fibre-coneNew optimized glass fibre cone design
  • Rigid steel chassis with extensive venting for lower air flow speed reducing audible distortion
  • Vented center pole with dual flares for reduced noise level at large cone excursions
  • Vented voice coil former
  • Heavy-duty fiber glass voice coil former to reduce mechanical losses resulting in better dynamic performance and low-level details
  • Large motor structure 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 plated motor parts for better heat transfer to the surrounding air

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.
