Wavecor Speaker Driver - WF146WA02 - 8 Ohm 5¾" Paper Cone Mid-Woofer
Description
The Wavecor WF146WA02 is an 8 Ohm 5¾" paper cone mid-woofer engineered for demanding bass and midrange performance
in high-end hi-fi systems, home theatre installations, and high quality multimedia setups. Designed for exceptional clarity
and wide bandwidth, it features an optimised paper cone that ensures smooth frequency response and low distortion across
its operating range.
Powered by a robust 90 mm magnet structure and a large 32 mm voice coil, the WF146WA02 delivers outstanding thermal and mechanical power handling. Distortion is further minimised through effective chassis and voice coil venting, combined with an internal aluminium field-stabilising shorting ring that stabilises the magnetic field within the air gap. The WF146WA02 is an excellent driver choice for compact 2-way speaker designs or as a dedicated midrange unit in multi-way speaker systems.
Features:
- Aluminium field-stabilising ring inside magnet assembly for reduced high-level distortion
- Vented voice coil former to minimise distortion and power compression
- Vented chassis design for lower airflow velocity, reducing audible air turbulence
- Heavy-duty black fibre glass voice coil bobbin for increased power handling and reduced mechanical losses
- Large motor system with 32 mm (1¼") voice coil diameter and 90 mm magnet for precise control and high efficiency
- Black-plated motor components for enhanced thermal dissipation
- Progressive suspension featuring a specially designed Conex spider for long-term durability under high excursions
- Gold-plated terminals to prevent oxidation and ensure long-term, reliable signal connection

Specification Notes:
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°C.
Note 5: Standard coil models simplify voice coil inductance. Wavecor utilises the advanced Wright empirical
model (TSL model in LEAP-4) using parameters Krm, Erm, Kxm, and Exm for increased simulation accuracy.
Note 6: Specifications after burn-in are measured 12 hours after driving the transducer with a 20 Hz sine
wave for 2 hours at 14.1 Vrms. Transducers are not burned in prior to shipping.
