It’s also the worst material to build horns with. Thu Jun 11, 1: I guess that’s what Gemme is all about. Considering that Robert was so forthcoming and enthusiastic I wish all manufacturers were this helpfulI thought it best to fowtex our email exchanges into a quasi interview. I won them on eBay for nearly half new price. Have you heard the Gemme Vivace speaker? Occasionally — as in the case of Robert or Green Mountain Audio’s Roy Johnson — someone has truly poured their heart and soul into their product and it seems only fitting to share this whenever possible.

The real thing is harmonics integrity, meaning the ability of a fe1088ez small driver to reproduce the sound of fundamentals and their harmonics in a pure and coherent way with fe108es crossover reconstruction.
