WF138WA02 is 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. WF138WA02 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
