Neo-fone
by Andrea Ciuffoli - starting in the October 2007

INTRODUCTION

I am starting with this project a full-range drivers test and I will compare many of this drivers in the 2007.

COMPONENTS

	These are full-range  loudspeakers using a single cone driver unit Neo-fone created by diyhifisupply 5.25"(130mm) to surround edge. Cast basket. Alloy cone. 50w power handling. Powerful neodymium magnet (self-shielding) with heat sink. 8 ohm impedance. 6.3mm Xmax. Tube friendly, check the impedance curve. I have found a fast and cheap method to build the chassie: Enclosure Point.
	To extend the band has been used a  Foster ribbon tweeter with lens and a simple filter with a 0.69uf MKP cap
