Wavecor

WF138WA04 is the 8 ohm version of WF138WA02, a mid/woofer designed for demanding bass and midrange applications. It works equally well for high-end hi-fi, high quality home theater systems, and top multimedia setups. It is powered by a large 90mm magnet structure that ensures good efficiency and optimal T/S parameters. The large 32mm voice coil ensure high power handling - thermally and mechanically The optimised paper cone ensures wide bandwidth and low distortion. Distortion is further reduced by efficient venting and an alu stabilizing ring. WF138WA04 is a good choice for compact 2-way speaker systems.

Features

  • Built-in alu field stabilising 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 fibre 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 90mm magnet for better control and efficiency
  • Long linear stroke motor for reduced distortion at high levels
  • 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
