Description: 6.5in. - 4 Ohm - Ferrite - WF166TU02

Wavecor Speaker Driver - WF166TU2 - 4 Ohm 6" Die Cast Car Woofer

Description
WF166TU02 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 1¼” 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 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 Measured at 25 deg. C
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.
