Overview

Fountek FR58EX 2" Neodymium Full Range Speaker Driver

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 2" FR58EX model is the smallest, and features a high-strength neodymium motor structure for low distortion, extended excursion, and excellent transient response. It’s a great choice for desktop multimedia speakers, micro-satellite speakers, or line arrays.
