Product Details

Fountek FR88EX 3" 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 FR88EX model features a high-strength neodymium motor structure for low distortion, extended excursion, and excellent transient response. Its advanced design makes it a true high-end contender in small full-range drivers.
