High-excursion design with 5 mm of Xmax
Neodymium motor with underhung voicecoil design
Black anodized-aluminum diaphragm
Cast aluminum frame
Fountek has applied much of what it has learned from designing industry-leading ribbon transducers in creating its line of full-range drivers. These high-performing cone drivers feature thin-foil aluminum diaphragms that shed resonance rapidly, for exceptional detail and smooth frequency response.
The 3" FR89EX model features a high-strength neodymium motor structure with underhung geometry, for low distortion, extended excursion, and excellent transient response. It’s a great choice for compact projects that demand the very best performance from a small full-range driver.
