Fountek - FR89EX - 3" Neodymium Full Range Speaker Driver

Overview:

Fountek’s FR89EX full range driver features an attractive black anodized aluminum cone, robust cast-aluminum frame, and an optimized long-excursion neodymium motor, for low distortion and excellent detail.

Product Highlights:

  • Smooth, extended frequency response from 70 to 20,000 Hz

  • High-excursion design with 5 mm of Xmax

  • Neodymium motor with underhung voicecoil design

  • Black anodized-aluminum diaphragm

  • Cast aluminum frame

Product Description:

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.
