Designed for use with 1.4” throat horns, the CDX14-3040 is driven by a 75 mm (3") diameter voice coil wound with edge-wound copper clad aluminum wire (CCAW) on a non-conducting former driving a single-piece titanium diaphragm and surround. Celestion also supplied its new 1.4” H14-7050 70°x50° constant directivity horn. This article was originally published in Voice Coil, April 2020.
